The UK has a strong affinity with the gambling industry, with casino games a growing part of an ever-expanding market. One of the leading markets in Europe, the online casino sector has been a large contributor.

The number of players has more than doubled in the last decade, with a player base of 36.43 million in 2022/23, compared to 16.53 million in 2012/13. Participation in online casino games only accounted for 3%, with 44% favouring the National Lottery.

The number of players playing casino games online is expected to increase. This page provides detailed information about the types of games available and explains how they are played, with free casino games available for practice.

Different Types of Casino Games

Several different types of casino games are available to players within the UK market. Players can enjoy:

• Slots
• Table Games (blackjack, roulette, baccarat, dice games, craps, poker)
• Live Dealer Games
• Instant Win Games (Scratchcards, Crash Games, Mine Games)
• Bingo
• Keno

In April 2024, 48% of survey respondents (5,126) had revealed that they had participated in some form of gambling within the previous four weeks, with a further 38% participating in online gambling.

The National Lottery continued to remain at the top of the statistics, with 32% playing regularly. Online instant win games accounted for 8%, with fruit and slot games a further 4%. Casino games continued to remain at 3%.

Many of the top gambling games have emerged as popular options due to their simplicity. Players know that they will encounter simplistic gameplay.

This allows them to play games without worrying about rules or strategies, which is particularly beneficial given the limited time they may have due to their busy lives.

According to the National Office for Statistics, the UK population spent an average of 3 hours and 44 minutes on entertainment and socialising as part of their free time, per findings in March 2023.

In March 2020, this figure was higher, as they would spend an average of 4 hours and 30 minutes. With less time available to them, they can focus on the entertainment offered rather than spend it trying to learn complex rules or strategies.

Online casino games are more accessible and convenient. Players can access an online casino at any time from their smartphone or tablet.

This has eliminated the need to visit a traditional brick-and-mortar establishment, which can be challenging due to the lack of daily free time.

With games accessible at the touch of a button, British players can enjoy them from the comfort of their own homes or with friends.

How to Get Started with Casino Games

British players looking to get started with playing casino games can do so by following a straightforward step-by-step process.

Online casinos in the UK market have made it as easy as possible for players to get signed up and start playing, while ensuring that the right protections are in place at all times.

They have not compromised on any step or made shortcuts, ensuring the market remains one of the safest in the world.

To get started playing casino games online, the following steps should be taken:

1. Visit an operator of your choice – those listed at BestOdds are highly recommended, as they have been thoroughly tested by experts to ensure safety. They are licensed by the UK Gambling Commission, meaning you are protected as soon as you sign up.
2. Sign up – once happy with the selected operator, sign up by following the steps that are requested. This will feature KYC (Know Your Customer) steps, which will include information about eligibility. Personal identification details, such as name, address, and date of birth, will be required, along with an email address and phone number. Some may require proof of identity at this point and may request an upload of a passport or driver’s licence, and proof of address. If not already done, it will be necessary when withdrawing any funds; however, it is best to complete it as early as possible to avoid potential delays or issues.

3. Make first deposit – Once signed up, a first deposit can be made. Select a payment option that is available and meet the minimum requirement (more can be deposited if desired). A welcome bonus may be available at this stage and is worth checking out. Some operators allow players to revisit it later and claim, but others will require it to be opted into at this stage of the process. Most casinos in the UK allow instant deposits to be made, but it can be important to check this beforehand.

4. Picking a casino game – After the deposit has been made, players can search for the casino games they want to play. Browse the operator’s library to find a title to play. Most will offer filters that help players to sort games by category, software provider, or even what’s popular or new. Most will also feature a search bar, allowing players to type in the name of a specific title they want to play and find it easily. Some may even offer an opportunity for players to be picked a random title to play.

5. Play the game – The final step of getting started with playing casino games online is to begin playing them! Make sure to understand the rules of the game and how bets are made. Understanding these aspects will ensure a better time, as poor decision-making can be reduced and bankroll can potentially be saved, allowing players to prolong gaming sessions for longer. Each game will have its rules and guides on how to play within it, so be sure to check these out before making the initial bet to get a full understanding of what to expect.

Online Slots

Online slots are growing in popularity with the British public. The UK Gambling Commission noted in a report in 2024 that gross gambling yield (GGY) had increased by 11% year-on-year in the reporting period, jumping to £614 million; this was at a 3% increase of each active player year-on-year.

In addition, the number of spins made on online slots increased by 12% in the reported quarter to 22 billion, marking a new peak. The number of average monthly accounts had also risen, with 4.2 million being active (a 7% increase).

The online slots market is extensive, offering a range of games to play. Variations can include different in-game mechanics (such as Megaways, tumbling reels, and cascades), bonus features (like free spins and pick-em games), and formats (including 3-reel, 5-reel, cluster pays, and paylines).

Slots can come with different volatility levels, which refer to the frequency of payouts. They have nothing to do with return to player (RTP) rates.

Games can be equipped with low, low-medium, medium, medium-high, and high volatility levels. Low volatility titles will see rewards earned frequently, but of a small size; high volatility slots will see bigger possible rewards, but at a less frequent rate of return.

Slots with High RTP

In addition to various mechanics and features, online slots are casino games that can be equipped with different return to player (RTP) rates. Some slots can come with higher RTPs than others. The industry average is set around 96%, but there are some slots with high RTP that can be found that are as high as 98%+.

RTP refers to the mathematical and theoretical returns that a player can expect to receive when they play. This is calculated with a percentage score of 100%, although it is not determined over 100 spins.

Millions of independent and random spins have been made, providing a statistical return over the period. This has then provided a theoretical rate of return that players can expect, using the algorithm that has been implemented to create the RTP.

The algorithm is a random number generator (RNG), and cannot be tampered with by anyone once the software provider has implemented it. A trusted casino will have this tool implemented within their games as it makes the titles as fair and safe as possible to play.

Slot Reviews

Reviewing slots is an important aspect. Showing what to expect and how to play is a critical component in ensuring a positive gaming session can be enjoyed when playing online casino games, whether it be for the first time or the thousandth.

Slots are tested using the following methodology:

1. Go to the slot and click ‘Play’ – Getting a firsthand experience is the best way to show others what to expect from a game. Too many simply look at a slot and give an educated guess based on previous experiences. Our experts test each game for themselves to get a real feel for it, allowing them to understand the nuances and find any potential hidden aspects that can be overlooked by those who don’t play it.
2. Spend time playing – Playing for a few minutes isn’t always enough to gain a detailed understanding of a game. Our experts test each game for a specific period of time, ensuring each reviewed title is given a fair and standardised review process. It allows an informed opinion to be formed, as titles are compared to others on an equal footing.
3. Software providers – The online slots world is filled with numerous casino game developers, which can make it challenging to know where to look or what to play. The experts will take these into account when analysing and reviewing the slots they play, as each one can provide something different regarding gameplay to players. Some may excel in terms of graphics, themes, and visuals, while others may be better in terms of mechanics or payouts.

In the dedicated slot reviews section, experts will focus on each title’s mechanics and the different software providers.

Players can find a directory of all our slot reviews and free-to-play demos there.

It is highly recommended to play the demos available, as this allows them to practice each one and gain their own firsthand experiences to form an informed decision based on their own preferences and playing style before committing to spending real money.

Online Roulette

Table games are hugely popular in the UK, with online roulette being the most popular casino game that does not include slots. According to the UK Gambling Commission, 36% played virtual roulette in 2023, with a further 29% playing the live version of the game.

Several variants exist in the UK market, which is one of the reasons why the game has been so popular. Its simplicity is another factor. The game does not require a great deal of skill, although strategic play can be employed.

Players are required to bet on where they believe the ball will land on the wheel once the dealer has released it.

A variety of bets can be placed at the table, making the game interesting and offering multiple reward sizes for those who are successful.

American Roulette

A popular version of the classic casino game is American Roulette. The game features 38 pockets, as it contains an additional double-zero pocket compared to other options.

The numbers on the wheel are arranged in a specific counterclockwise order, and there are no adjacent numbers of the same colour.

The house edge in American roulette is 5.26%. Of the 38 available, 18 pockets are black, 18 are red, and the two zero pockets are green.

European Roulette

An alternative to American Roulette is European Roulette. This version of the game is very similar to its American counterpart, although it contains one fewer pocket. Numbers 1-36 can be found across the wheel, as can a single zero.

The only pocket that doesn’t exist on this wheel is the double-zero. The house edge of this game is 2.7%, making it a highly popular option for UK players, as they have a theoretically greater chance of winning compared to the American version.

French Roulette

French Roulette is another popular variant that is enjoyed, although not as much as the others. It features a layout identical to the European version in terms of the numbered pockets used, although the table layout and pocket order may differ.

Different rules can exist in this version compared to others, with special rules such as “En Prison” or “Passe-Caisse” that can further reduce the house edge, even below the standard 2.7% it shares with European Roulette.

Roulette Systems

Roulette is one of the casino games that can be positively impacted when using certain strategies. Many will play with hope and gut-feeling, but by using one of the many roulette systems that exist, players can maximise their chances of having a potentially successful time.

D’Alembert Roulette System

The D’Alembert Roulette System is a strategy that focuses on negative progression. Players will reduce their stake after each win that occurs, while increasing it after each loss. A player is required to work in units, which is often a percentage of their starting bankroll.

If £100 is the starting point, then a betting unit will be between £2 and £5 for its maximum impact. If a loss occurs, a player would add between £2 and £5 to their stake for the next one. If it wins, the bet would be reduced by the same stake unit.

Fibonacci Roulette System

An alternative negative progression strategy used by many in the UK is the Fibonacci Roulette System. This strategy uses a system that follows a sequence of numbers that was used by an Italian mathematician called Leonardo Bonacci (commonly known as Fibonacci).

His sequence is: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.

Players would place a stake based on the two previous numbers combined. For example, bet one would be worth 1 unit and if it were to lose, the second would be worth two units.

If that were beaten, bet three would be worth three units as it sees bet one and two added together. Bet four would be worth five, as three and two would be put together, and so on.

If a win is recorded, the sequence would go in reverse for the next bet. If it loses, it will return to the way it was previously being followed. 

Labouchere Roulette System

The Labouchere Roulette System is unlike any other roulette strategy, as it requires players to follow a pre-planned methodology before placing a bet at the roulette table.

• Step 1: Decide on a realistic amount of how much wants to be won. This needs to then be split into numbers. An easy example is to think about £10 as a winning total. This can then be split into numbers like 1, 2, 4, 1, 2.
• Step 2: Combine the numbers together, with the first and last added together for the first bet (1+2). Afterwards, the numbers between can be added together. In this instance, a bet of £3 should be placed.
• Step 3: Place the bet on an even bet to maximise the chance of winning. This may involve betting on odd/even, red/black, 1-18, or 19-36.
• Step 4: Repeat the formula from Step 2. If a win occurs, you can cross off the two numbers that combined to secure the win. If you lose, add the bet made to the end of the sequence and use it for the next bet.
• Step 5: Repeat the process until a win is achieved.

Martingale Roulette System

A famous roulette strategy, the Martingale Roulette System, is hugely popular. It is one of the easiest to follow and understand, which is why many British players continue to use it when playing casino games online.

This strategy involves players doubling each bet they make when it loses. It is a system that is based on recovering losses, although there is no guarantee that it will.

Once a bet is won, players will start betting from their initial stake and start again. Focusing on even-money bets (1:1) is the best way to use this strategy, although risks still exist.

Online Blackjack

Blackjack is another popular online casino game widely enjoyed by British players. Both virtual and online forms of the table game saw 27% of players surveyed in early 2024 state that they had spent money on these options across the previous 12 months.

It’s a simple game to play and one that is just as recognisable and familiar as roulette. In blackjack, the main premise is to beat the dealer by being as close to a value of ‘21’ without going bust.

Players can come under, but they need to have a score that is greater than the hand of the dealer if they are to win.

Several strategies can be adopted when playing online blackjack, and many variants exist that offer different side bets. 

American Blackjack

Also known as Classic Blackjack, American Blackjack is the version of the game most played by British players. It requires players to get as close to 21 as possible without busting.

In this version, the dealer will hit on a “soft 17”, meaning they will continue to deal if they have an Ace and other cards that total 17.

Players can decide whether to hit (draw another card), stand (keep their current hand), double down, or split their hand (if they have two cards of the same rank) in this game.

European Blackjack

European Blackjack is slightly different. While the main premise of the game remains the same, the gameplay rules differ. In European Blackjack, the dealer does not check for Blackjack when showing an Ace or 10, and the player’s bet is lost if the dealer has Blackjack before the player takes any actions.

Restrictions can also exist regarding certain cards when splitting, although doubling down is still possible. Fewer decks are typically used in this version of the casino game.

Spanish 21 Blackjack

Similar to Classic Blackjack, Spanish Blackjack is a variant that can be enjoyed by British players. In this version, the number 10 cards are removed from the game. This means a deck will consist of 48 cards and not the standard 52. Players can hit or stand while playing this game, with a few game features differing slightly from the traditional version.

Blackjack Systems

Blackjack can be played using strategies designed to maximise win potential. Four Blackjack systems can be commonly found.

D’Alembert Blackjack System

The D’Alembert Blackjack System requires bettors to increase their bet by one unit after each loss. Each time you win, the bet will be decreased by one unit. However, if a loss occurs, the next bet would be increased. The approach is based on a strategy of negative progression; much like it is when used as a roulette strategy.

Fibonacci Blackjack System

A Fibonacci Blackjack System can be adopted as a betting strategy. Players following this system will use the same sequence outlined for Roulette (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.), but for each bet they make when playing Blackjack. Players will add their last two stakes together using the sequence for their next bet.

Labouchere Blackjack System

The Labouchere Blackjack System is a flexible betting strategy that can be used. It uses the same steps outlined above, with players needing to follow a process of steps to maximise its effectiveness.

Martingale Blackjack System

Players may choose to use the Martingale Blackjack System when playing this casino game online, as it can be the easiest to follow. They simply need to double their bet on each loss that occurs. When they get a win, they will return to their initial bet and start again.

Online Poker

In 2024, 29% of UK players surveyed participated in online poker over the previous 12 months. It is a game that has enjoyed growing popularity among British players. It combines a mix of skill, strategy, mental toughness, and a level of competitiveness that other online casino games lack.

Online poker comes in various forms, each offering a distinct flavour. Most will involve creating the strongest hand possible. Still, players must familiarise themselves with the rules and strategies that can be employed before playing, as these games can be very taxing on the bankroll.

Draw Poker

Draw poker is a poker variant in which players are initially dealt a complete hand. After the hand is dealt, they have an option to discard cards that have been received and replace them to try to improve their hand.

They can only do this during the initial betting phase, with a final betting round and showdown taking place after. The player with the highest-rated hand will win the pot.

The game is primarily based on decision-making and strategy, offering a distinct experience from other forms of online poker.

Chinese Poker

A very different online poker game, Chinese Poker involves players being required to divide the 13 cards they have been dealt into three hands. This will consist of a front hand of three cards, a middle hand of five cards, and a back hand of five cards.

The aim is to have the best possible poker hands, with the back hand needing to be the strongest, and the front hand being the weakest. No bets are made during this game; points are used to score it.

Omaha Poker

A popular variant of online poker, Omaha Poker is one of the casino games that is widely enjoyed by players of online UK casinos.

This version of poker is very similar to Texas Hold’em, as it features a community of cards that need to be integrated into the player’s hand as best as possible to create a strong hand.

The main difference between this game and Texas Hold’em is that it involves four cards being dealt. Players must use at least two of these cards to form their strongest hand, as well as three of the community cards to make a five-card hand.

Several Omaha variants exist that can suit multiple player preferences and styles.

Stud Poker

Stud Poker can be played with five or seven cards, with both differing slightly.

In this online poker game, players can either receive one hole card and four face-up cards with betting rounds between each face-up card being dealt (five-card Stud) or two hole cards and one face-up card initially.

Three more face-up cards and one final hole card are dealt after a round of betting (seven-card Stud).

Players will form a five-card hand at the end of each game, but in seven-card Stud, they must select the best five from the seven they receive. This requires a focus on strategy.

Texas Hold’Em Poker

The most popular form of online poker in the UK, Texas Hold’em, is a classic casino game that has been enjoyed widely. It is the form most recognised or associated with poker, given its usage in other forms of entertainment.

Like Omaha, it involves a community of cards that need to be paired with to create the strongest hand possible. However, only two hole cards are dealt in this version.

Players can’t add to their hands or change them. They must decide whether to call, raise, or fold with each betting round before showing their hands at the end.

Online Baccarat

Online baccarat is a simple card game that is being enjoyed by British players. The objective of this game is for players to successfully bet on whether the Player’s hand or the Banker’s hand will have a total value closest to nine.

A Tie bet can also be placed. Some versions will feature side bets exclusive to their baccarat variant.

Two cards will be dealt to the player and the banker, although some variants of the game may allow a third to be dealt. Each card will be added together to create a value.

Any values in double-digits (total of cards added together or cards of a value of 10) will see the first digit dropped. For example, a hand of 9 and 7 will be worth six and not 16. All face cards and 10s are worth zero.

Online Bingo

Bingo is a classic British game that has only grown in popularity with its rise as an online casino game. Approximately 5% of respondents in a 2024 UK survey were found to be playing the game. Online bingo can be widely played across the UK, with 45% of players opting to play the game exclusively through this method.

Online bingo works in exactly the same way as the traditional version of the game. Numbered balls are called and fill out a player’s card. Those who fill their card can win the top prizes, while some variants may include lines or other bet types.

Some variants differ in terms of the number of balls played with, with 75-ball, 80-ball, and 90-ball bingo being among the most popular.

Game Shows

Another type of betting on casino games that has become popular in the UK is game shows. These games have allowed players to wager on games that are like the shows that have been widely enjoyed on British television as part of a Saturday night’s entertainment.

In 1938, the very first game show was broadcast in the UK, being the Spelling Bee.

Many casino games have since been created based on popular formats, with wheel-based games often used.

Shows like Wheel of Fortune used a wheel to allow contestants to spin for cash when successfully guessing the right letters of a word/phrase. The wheel concept has since been used to allow bettors to try to predict certain betting outcomes.

Live Casino Games

Game shows have become very popular live casino games, which is another form of casino gaming that has boomed in the UK recently. These games provide an authentic experience using technology, bringing a traditional casino session into a person’s home.

Players can enjoy games with real human dealers, immersing themselves in a gameplay session akin to those found in a physical brick-and-mortar establishment, without the hassle of traveling to one.

Live Poker

Live Poker is a game that has been enjoyed by many. Players can compete against others virtually, while still enjoying many of the physical realities that come with playing the game.

Games are streamed across the internet, allowing players to focus on their strategy without having to worry about giving away tells to their opponents.

Each game remains professional, as a live dealer will still be involved and can oversee gameplay, ensuring it is played correctly and in the proper manner.

Live Roulette

Live Roulette is exactly like the experience that British players would receive if they were standing at a table in a traditional casino setting. Players can place their bets as they would normally, with a professional human croupier managing the game.

The game is played in the same manner and is streamed through the internet, with monitors focusing on the table and then the wheel when the ball is being spun.

Live Baccarat

You can get an authentic experience when playing Live Baccarat at a live dealer casino game site. As noted with the explanation for traditional Baccarat, the live options are no different in terms of their gameplay.

Instead, they are played in a studio that mimics a real casino environment. Players will come up against a real dealer who will deal the cards.

Live Blackjack

Live Blackjack is a hugely popular game for UK players, as they can receive the same type of experience as in a real casino. The game’s premise remains the same whether it is played physically or virtually.

Games will be played over the internet, simulating a real dealer, rather than a studio setting. Croupiers are highly trained and professional, giving a level of authenticity.

Online Jackpots

A game that is enjoying growing popularity amongst British players is online jackpots. These are slot-based games that feature an additional aspect that allows players to try and win bigger rewards. They are features that are added within slots, often coming in various forms. They can include:

• Progressive Jackpots – a jackpot that increases with each bet made and often across a network of games.
• Fixed Jackpots – jackpots that are seeded at a maximum value. Three or four can be obtained in certain games.

Jackpots are typically won randomly, with players simply having to spin the reels and hope they trigger them. However, some games allow jackpots to be triggered through bonus features. Game rules will specify how they can be won.

Casino Game Developers

The UK casino market contains several reputable casino game developers. It is why our experts have created dedicated review pages for each of them. Among the most popular include:

• Evolution
• Pragmatic Play
• Play’n GO
• NetEnt
• Games Global
• Blueprint Gaming

Our review methodology includes rating game providers based on the diversity of their libraries, as well as reviewing casinos in detail and the games they offer.

Those who score highly do so because they provide titles that cater to the needs of several types of players. This can include games that cater to different play styles, bet limits, immersion levels, or utilise specific mechanics and features to make themselves unique from other software developers.

Game providers create titles using specialized technologies and software. Cloud technology is used to ensure that games can be played across the various casinos and networks, as updates can be made without interrupting playing sessions.

Other technologies used by developers include HTML5, which can be hosted on the web and mobile devices, as well as JavaScript technologies.

Games will also feature random number generators (RNGs) to ensure fair play. These algorithms help to create unpredictable and randomised outcomes.

They are independent of each other and cannot be tampered with, ensuring players receive the fairest sessions each time they play and allowing trust to build.

Our Methodology for Reviewing Casinos Based on their Game Collection

Our review methodology places a huge emphasis on game providers. Ensuring the best gaming is a priority, which is why focusing on everything that game providers offer is a must as part of our process.

We analyse how complete the provider is, examining the various games offered and their design. We examine what’s offered within each one and how they differ from others available, analysing the pros and cons of each and whether they suit player preferences.

We also examine how diverse the library is in catering to players of all types, because casino players are not all the same. While everyone wants to enjoy the very best gaming sessions, their appearance can be quite different.

Legality of Online Casino Games

The legality of online casino games in the UK can be complex. For a casino to operate legally in the UK, it must obtain a licence from the UK Gambling Commission (UKGC).

This is a mandatory requirement. The licensing process is strict and rigorous, as a thorough assessment of every area of a casino will be analysed and scrutinised by the authority to ensure players are protected.

To play at a UK casino, players must be at least 18 years old. Casinos must verify a player’s identity before they begin playing. Limits on casino games exist in the UK, with players under the age of 25 only permitted to bet a maximum of £2 per spin on a slot machine.

Additionally, playing casino games in the UK with funds deposited with a credit card is illegal.

Tips and Tricks When Getting Started with Casino Games

Players can take advantage of several tips and tricks when playing casino games, some of which aren’t always shared or widely known.

While there are many examples that are common knowledge – don’t chase losses, don’t play under the influence of substances, knowing when to stop and being disciplined with bankroll – there are some methods that can be used that can make a huge difference.

1. Playing Games Based On RTP Rate

An incredibly overlooked yet simple thing to do is to only play casino games online with favourable RTP rates. As explained briefly, the RTP rate is the theoretical rate in which money can be returned.

While slots can look the most appealing because of their added mechanics, jackpots, and themes, they can be among the worst in this regard. The industry average is only 96%, but many can be lower than that. Table games can be as high as 99%. Although returns aren’t guaranteed, these games offer a greater chance of them happening compared to slots.

2. Take Regular Breaks

In the UK, everyone has heard about how taking a break (…and have a KitKat) can have a positive impact. They can be difficult to take in reality, especially in working lives. Many often have to work through them.

When it comes to playing casino games, it’s imperative that they are taken. A break can make a huge difference to a playing session. Players can remain in greater control of what they are doing, ensuring they limit the risk of potentially poor decisions being made (such as beginning to chase losses or playing beyond an individual’s means). By taking frequent breaks, a safer and more positive session can be enjoyed.

3. Play Demo Games

It can often be forgotten that games can be played for free and do not have to immediately be played for real money. It’s important to remember that free casino games do exist, with many of the biggest titles and classic releases featuring demo modes.

These titles can be played risk-free, allowing players to practice a gameplay session in the same way as if they were playing with real money.

They can be used to learn the different aspects of the title, allowing gamers to familiarise themselves and practice strategies before risking real funds.

Free casino games can be played within our slot reviews, with titles being linked to their demo version.

How to Choose the Right Casino Game for You

Of course, picking the right casino games to play is vital. It’s one of the most important things British players can do to have fun from the get-go. However, picking the right game for you can come down to several factors.

Playstyle

Depending on how a player wants to play a game, not all titles will suit their preferences. For example, players who prefer fast play and are attracted to the biggest wins may want to give slots a try.

Those who prefer a more strategic approach or want slower gaming that is more sociable may want to play live dealer online casino games.

Indeed, determine how you like to play your favourite games before picking one to make sure the best possible session can be enjoyed.

Experience Level

Again, a player’s level of experience can have a significant impact when picking the right casino games to play. Players should recognize their strengths and weaknesses, picking those they understand and know how to play.

Of course, playing free casino games can help improve areas of weakness and build experience, but never enter a real-money title without prior knowledge or experience of what to expect.

Budget and Expectations

The right casino game depends on a player’s budget and expectations. Games like slots can see bankroll depleted very quickly because spins only take a second to complete.

Table games can be longer in duration, but they may not provide as big rewards as a slot can.

A player who has set themselves a budget before playing and has kept expectations realistic will be able to identify which games are right for them and which ones are not. Experience can also come into play.

RTP Explained

Return to Player (RTP) has been mentioned extensively already. In its simplest form as a definition, it is a key metric in casino games that indicates the percentage of wagered money a game is expected to pay back to players over time.

It’s a theoretical calculation based on long-term play, expressed as a percentage, with the difference between the figure and 100% being the casino’s expected profit (house edge).

Take a slot game with an RTP rate of 96%. This means that £96 is expected to be returned for every £100 wagered, with £4 going to the casino as profit.

However, RTP does not work like that in reality. It is calculated over millions of spins, which is why it is a theoretical return. A player can win more or lose everything when playing a game, and not experience the return that is expected; it’s just what would be expected over a significant period of time.

As noted throughout, games vary in terms of their RTP rates. Slots can average at 96% but can be anywhere between 88% and 98% (sometimes outside this range, too).

Table games like blackjack can have a higher RTP, which can be increased with the right strategies. This can help players to make informed decisions about the games to play and perhaps which ones to avoid, helping to build transparency between players and the industry.

It’s important to recognise with slots that RTP does not account for volatility. The volatility rate determines how often and how large payouts are. High-volatility games may have the same RTP as low-volatility ones but pay out less frequently in larger amounts.

RNG Explained

Another technology used to create casino games and make them as fair as possible is algorithms known as random number generators (RNG). This tool keeps games unpredictable by making results random and independent of each other.

It’s a software algorithm or hardware device that generates sequences of numbers or symbols without any discernible pattern, simulating the randomness of physical casino games like dice rolls or card shuffles. They can be found in various types of online casino games.

RNGs continually produce random numbers with each action and use a process that maps the outcome. For example, when a player initiates an action in a casino game, the title will use the RNG’s current number to determine the outcome.

That number has been pegged to a specific result, such as a symbol appearing on a reel, a card being dealt, or the ball landing in a certain pocket on the roulette wheel.

RNGs are regularly tested and rigorously, ensuring they haven’t been corrupted in any way. This ensures fairness, as results cannot be manipulated by casinos or anyone else.

To ensure they meet the required standard, RNGs must be certified by an independent auditor, such as eCOGRA or iTech Labs, as these bodies can verify randomness and compliance with fair gaming standards.

Misconceptions can exist around RNGs. Players can believe that their luck is about to be in when on a losing streak, or they may feel games have been rigged.

This is not the case, as they have been designed to eliminate any possibility of this happening, while the technology used ensures each result is independent of any other.

Understanding Casino Game Odds

While RTP and RNGs play a role, casino games are based on mathematical probabilities. Depending on the type of online casino game being played, certain calculations exist that can help players to understand their actual chance of winning.

Slots

Slots feature various probabilities due to their unique makeup. Slots can feature various paylines, reels, symbols, and numerous other elements. This can make the equations regarding mathematical probability a little harder to determine.

To keep things simple, let’s work with a slot that has five symbols and just three reels. This means the total number of possible outcomes is 5 × 5 × 5 = 125. If a jackpot requires three specific symbols to fall, the probability of hitting this is 1/125 = 0.008%.

In terms of paylines, if a game has 10 paylines, each payline will have its own mathematical probability.

Odds can be increased if all paylines are active, but per-payline odds will remain the same per spin. Volatility can also impact the mathematical equation, as this impacts the frequency and size of payouts.

Blackjack

Depending on the blackjack variant being played, the mathematical probability can be impacted significantly.

A single-deck game will feature 52 cards, although some variants can include up to eight. Taking a one-deck game as a simplistic example, the chance of drawing any one card is 4/52, which translates to being 1/13 (0.0769%).

Once a card has been drawn, the probability changes significantly. Another of the same card will see its odds change to 3/51 (0.0588%), whereas another card will be 4/51 (0.0784%).

Using a single deck, the probability of landing a natural blackjack is 4/52 (Ace) x 16/51 (16 cards with a value of 10 and once an Ace has been drawn from the deck).

This equation equals approximately 0.0241%. This figure can be slightly lower when more decks are added to the game.

The house edge is much lower in table games like blackjack compared to slots because the mathematical probability is identical for the dealer as it is for the player.

Roulette

Depending on the variant that is played, the mathematical probability for online roulette games can differ slightly. Remember, American Roulette features an additional pocket (double zero) than its European version. The number of pockets makes a huge difference in the house edge and return for players.

European Roulette has 37 pockets. The probability of a single number is 1/37 = 0.0270%, hence why this version has a house edge of 2.7% and an RTP of 97.8%.

In American Roulette, the probability of landing a single number is 1/38 = 0.0263%. However, the house edge is 5.26%, with the RTP 94.74%. This is because the expected value is worked out at -0.0526% (1/38 x 35 + 37/38 x -1).

The bet type placed can also make a difference to the mathematical probability, with outside bets offering higher probabilities. Red/Black, Even/Odd can return 1:1. In European Roulette, the win probability is approximately 18/37 = 0.4865%, with the house edge remaining 2.7%.

Poker (Texas Hold’em)

Taking Texas Hold’em as the most enjoyed poker variant, the mathematical probability that exists for this game is as follows:

The game is played with a 52-card deck (single deck). A starting hand of a pair is 4/2 / 52/2 = 6/1,326 = 0.0045%. For community card outcomes, calculate flop, turn, and river probabilities. For example, with a flush draw (9 outs) after the flop, the probability of hitting by the river is: 1 – (38/47 x 37/46) = 0.351%. 

The house edge comes from the rake in this game.

Baccarat

Many variants of online baccarat exist, although the most common typically involves eight decks (416 cards). Odds of each bet winning are as follows:

• Banker wins: 45.86%
• Player wins: 44.62%
• Tie: 9.52%

To work out the probability of a game using this number of cards, the following formulas can be used:

Player bet (1:1 payout) is worked out (0.4462×1)+(0.4586×−1)+(0.0952×0) = −0.0124%, giving house edge of 1.24%.

Banker bet (1:1 payout minus 5% commission in some variants) is worked out (0.4586×0.95)+(0.4462×−1)+(0.0952×0)≈−0.0106%, giving house edge of 1.06%

A Tie Bet (8:1 or 9:1) is worked out (0.0952×8)+(0.9048×−1)≈−0.1436%. House edge is 14.36%.

Casino Game Strategies

Casino game strategies can be used to maximize player success by taking into account the mathematical probabilities, game rules, and the way games are played. Although there are no strategies that can guarantee winning outcomes due to the inclusion of RNGs, they can help reduce the house edge or keep players safe and prolong sessions.

Different games can require different strategies. Examples of strategies that can be used for each game include:

• Slots – Choosing high-RTP games, playing titles with a high number of paylines, understanding volatility, utilising bonuses, and managing your bankroll are among the best strategies to employ. Slots are purely random due to their RNGs, but strategies can help to maximise enjoyment.
• Blackjack – Using a strategy chart can maximise success, as it provides the probability of cards being dealt after a starting hand. Understanding rule variants and managing your bankroll are also useful strategies to employ.
• Roulette – Playing European Roulette is one of the best strategies available for this game, as the house edge is lower than American Roulette. It’s also worth focusing on outside bets, as these can return more frequent wins. Certain strategies (as outlined already) can be used when placing bets.
• Poker – Strategies can include playing on strong starting hands and folding on weak ones. Use position play to increase win potential, while bluffing can also be a useful technique to try to win the pot.
• Baccarat – Betting on the Banker and avoiding the Tie bet are the best strategies to adopt when playing baccarat. The house edges are very different, with the Banker bet almost at 1% (1.06%) compared to the 14.36% edge that the casino has for a Tie bet. It is also important to avoid pattern betting, as an RNG ensures that each game is independent of any other that has been played.

Responsible Gaming

The importance of Responsible Gaming cannot be understated. The UK Gambling Commission prioritises this by enforcing stringent measures and regulations to protect players.

Responsible Gaming involves understanding the risks of gambling, setting strict budgets, and maintaining discipline to prevent financial or emotional harm.

The UKGC mandates that licensed operators provide tools such as deposit limits, time-out periods, and self-exclusion options to empower players to manage their gambling responsibly.

Players must approach gambling as entertainment, not a source of income, and never deposit more than they can afford to lose. By keeping a close eye on bankroll and adhering to personal financial limits, players can mitigate the risk of overspending and ensure gambling remains a controlled activity.

Several organisations are in place that can provide further assistance to players who feel they need support. The most prominent ones in the UK include:

• GamStop
• GameCare
• GambleAware
