The 100 Free Spins bonus is a promotion that the player can sometimes encounter when registering on a UK online casino, and as bonuses go, it is one of the more generous ones. While it can be tied to the welcome bonus, it can also make an appearance as a VIP perk or a promotion for existing players. 

The best part of this bonus is that it offers 100 free spins, meaning that the player gets to engage in lengthy gameplay on one or several slot titles without having to use their own money. 

However, they also come with certain terms and conditions that the players must be aware of to get the most out of this promotion. Any terms tied to the bonus must be clearly displayed under the UK Gambling Commission’s (UKGC) laws, so all licensed casinos must have them specified on their respective platforms.

This page will discuss the nature of the 100 Free Spins bonus, how to claim it, what standard terms might accompany it, and several other essential considerations, including ways to engage in responsible gambling.

What Are 100 Free Spins in the UK Casino Context?

In the UK online casino landscape, the 100 Free Spins bonus is a casino bonus that refers to a set of 100 spins on one or several of the platform’s slots. These are free spins, or bonus spins, that are provided to the new player as a welcome offer or to existing players as a reward if they deposit a certain amount of money.

Typically, it is seen in deposit-based welcome bundles, but rarely, if ever, as a non-deposit-based bonus, due to the overwhelming number of free spins. The casino funds each spin at a predetermined stake, which is typically quite low, often sitting at around £0.10 to £0.20.

Note that any winnings made through the free spins are usually not made in the form of withdrawable cash, but rather, they are added to the player’s bonus balance. They can be turned into money that the player may withdraw, but that comes only after the player completes certain requirements, which will be discussed in detail later on.

For now, note that having 100 spins is substantial, and it allows the player to engage in a lengthy gaming session where their odds of triggering various bonus features within the games are notably higher than with lower spin sets, like 10 Free Spins, 20 Free Spins, or even 50 Free Spins

How to Claim 100 Free Spins

Online casino enthusiasts who wish to try out the 100 Free Spins bonus and check out the platform, its games, and their mechanics will first have to claim the bonus. While claiming bonuses is usually a simple matter, when it comes to more generous offers like this one, there are a few steps that the player should be aware of ahead of time. 

With that said, here is how you can claim 100 Free Spins on an online UK casino.

Sign up at a UK-Licensed Casino

The first thing to do is find a casino that offers the 100 Free Spins bonus, as not all platforms do. As mentioned, this is rather generous as welcome bonuses go, so the first task will be to find it. Along the way, players should make sure that the casino offering the UKGC licenses it, as non-licensed platforms are not safe to use.

Choosing a licensed casino will ensure that the platform follows strict rules regarding transparency, data security, fairness, and responsible gaming. If a website is not regulated, players should avoid it, as using such a website means putting their privacy and funds at risk.

But, assuming that the player managed to find a UKGC-licensed online casino that offers the 100 Free Spins bonus, their first step will be to create an account. This is easily done by clicking the “Join Now,” “Register,” or “Sign Up” button. This will lead the new user to the registration screen, where they will have to enter several details, like their email and name, create a strong password, and the like.

Alternatively, the platform might allow the player to register using an existing account, such as PayPal, Yahoo, or a similar service.

Verify Age & Identity (KYC)

Next, the player will have to verify their age and identity, which is known as the Know Your Customer (KYC) or ID verification. This is necessary for several reasons. First, casinos are required by law to determine their players’ age and identity, and also, the player won’t be able to withdraw any winnings before this process is completed.

Given that the process may take some time to be completed, the player should verify their ID as soon as possible, and allow the verification to be done in the background while they enjoy their free spins, and be ready to withdraw the winnings immediately once they fulfil other potential requirements. 

Since withdrawals often come with a time limitation, it might take too long to verify the identity once the player has already won some money. As a result, they might risk losing it due to the time limitation as they wait for the verification to be completed. Doing this beforehand makes things simpler when the time comes to withdraw the money.

On some online casinos, the KYC verification might be included in the registration process itself, which is the best way to ensure that ID verification is done immediately. If this is not the case, however, the players should seek out the verification form on their own before playing the games.

The process will involve providing their legal first and last name, date of birth, as well as proof of residence, typically through a photo of a utility bill or some government-issued document.

Deposit & Opt-In

While free spins can be encountered as a no-deposit bonus, this is usually not the case when it comes to versions that offer a large number of spins, such as the 100 Free Spins bonus. Instead, in order to claim it, players will likely have to place a deposit. The size of the deposit may vary from platform to platform, and casinos may require a minimum of £10.

With that said, it is also possible to claim this type of bonus through a bonus code or by ticking the promotional box. These details are left to each online casino to decide on its own. To grasp the full picture and understand the exact requirements, players should read the platform’s Terms & Conditions (T&C), which must make all requirements transparent and clear under the UK gambling laws.

Players should also note that the size of the promotion might lead the platform to offer the 100 free spins in increments, such as 20 spins per day over a five-day period, or 10 free spins per day for 10 days. This should also be specified in the T&C document, which is why reading it before claiming the bonus is important.

Select the Eligible Game(s)

Finally, with the funds deposited and bonus claimed, all that remains is for the player to start playing the eligible game or games. That means that the bonus will not be applicable to all games that the casino offers. Instead, it should only be tied to one, or potentially a several games offered on the platform.

Typically, this includes some popular slots that the casino aims to promote, such as Book of Dead or Starburst, and potentially a few more. Again, this is something that varies from platform to platform, and to know for certain which games are included in the promotion, read the T&C.

However, online UK casinos typically make it known which games players can spend their spins on, and some even create a dedicated button on their websites that will lead the player directly to the game(s).

Typical T&Cs for 100 Free Spins

Before diving into the 100 Free Spins, players must understand that this isn’t a simple gift from the casino. It is a promotional offer, but it represents a potentially sizable loss on the casino’s end, which is why it comes with some strings attached. Mainly, there are several terms and conditions tied to the promotion which must be fulfilled and respected to the letter in order for any winnings made from the free spins to be considered withdrawable.

Note first that under the UK gambling and advertising laws, these terms must be displayed upfront. Casinos might include them on their promotional page, but they must have them in their Terms & Conditions, so players should check both just to be sure they have a full understanding of what is required and expected of them.

With that said, one of the biggest obstacles to withdrawing the funds won via the free spins promotion is the wagering requirements. Most free spin bonuses come with such requirements attached, and they are applied to all the money won directly via the spins. Essentially, this money is not withdrawable. Instead, it is classified as “bonus funds,” and the player needs to match wagering requirements in order to turn that money into withdrawable money. This usually falls between 20x and 40x, although this can vary from one casino to the next.

So, if a player wins £10 and the requirement is 30x, they must wager £300 in total before they can cash out.

Then, there are time limits, which are also commonly applied to all free spin sets, but can be additionally complex when it comes to larger promotions like 100 Free Spins. This is because in most cases, not all spins are available at once. Instead, they can be broken into smaller groups of spins, such as 20 free spins per day over the course of 5 days. In this situation, each subset of spins may expire within only 24 hours.

If the spins happen to be available all at once, they may also have an expiration date, which could be anywhere from 24 hours to 7 days, depending on the casino’s rules. Finally, even if the player spends all of their free spins in time, the bonus funds that they have won will also have their own time limit, such as 7 to 30 days, depending on the platform. If the player doesn’t meet wagering and other requirements, these winnings will also be reclaimed by the casino.

Casinos also commonly have a maximum win or cashout limit, meaning that players can’t just use their free spins to win as much money as the games would allow and withdraw all of it. Most UK casinos will place a cap on how much the player is allowed to win, and the cap is different from platform to platform, and it even changes between different spin sets (10 free spins, 20 free spins, etc.). This is common with no-deposit deals, but it can also be encountered with deposit-based bonuses, although the cap tends to be higher if the player got the bonus after making a deposit.

Next, casinos also have slot limitations associated with free spins, where the players cannot use them on any slot on the platform, but instead, they have to use only one or a handful of predetermined slots. With 100 free spins specifically, the spins might be split across multiple slots, if the casino decides to set it up that way.

Lastly, there are also verification requirements, which prevent the user from withdrawing any money before they verify their identity. This is required by the UKGC rules, and casinos have no say in it. Simply put, that is the UK law, and both players and casinos must respect it.

No Deposit vs. Deposit-Based 100 Free Spins

When a player encounters a 100 Free Spins offer, it is important to immediately establish whether the offer is no-deposit or deposit-based. This type will determine much, including how much freedom the player will have, what restrictions may apply, and what the player has to do in order to claim the bonus.

No deposit 100 Free Spins are rare, as this is a massive number of spins for casinos to just give away for free, so most choose not to do it in the first place, and would settle for a smaller spin set. But, there are platforms that do offer them, usually as a strong sign-up incentive. However, this offer comes at a cost. Specifically, players may encounter stricter terms, like high wagering requirements or lower maximum cashouts. 

A lot more common is getting 100 Free Spins as a deposit-based bonus, which may be included in the welcome package, along with a match bonus. That means that the casino will match any amount the player deposits, and add 100 free spins on top of that. Usually, these promotions require a relatively modest deposit, such as £20, so they don’t represent a major investment for the player. But, they also come with fewer restrictions than no-deposit spins, which is a big benefit as it makes it easier to withdraw the winnings and make a sizable amount from the free promotion.

Deposit-based deals may also attach extras, like further free spins on subsequent deposits, so players could get even more than the initially promised 100 free spins, although this depends on each casino’s individual rules and terms of the deal.

Benefits of 100 Free Spins

When claiming the 100 Free Spins bonus on a UK online casino, the obvious benefit is getting 100 shots at winning money on a slot assigned to the bonus. However, there are several additional benefits that the players might not be aware of immediately.

For example, 100 spins provide an extended gameplay, which allows the player to explore all slot features very thoroughly, and potentially activate multiple bonus rounds, which could lead to even more spins and even greater earnings. 

Not to mention that statistically, more spins create more chances to land big symbols or free-spin rounds within the slot, which once again increases the potential payout for the player. But, there is also the fact that the players can get to become highly familiar with one or more slots that they can use their free spins on.

In other words, 100 free spins represent a perfect opportunity for players to experience a new and unfamiliar title without risking their own money. This could lead to the discovery of a new favourite game, and at the very least, it will let the player know if the slot in question is interesting enough for them to continue depositing funds and playing it after their free spins are spent.

Potential Pitfalls & How to Avoid Them

In the interest of transparency, it is important to note that, where there are benefits, there are typically also plenty of drawbacks or pitfalls that players should also be aware of. After all, whenever there is money on the line, there are multiple sides interested in earning it, so keep the following in mind, as it usually comes as the “other side of the coin” associated with free spins.

The first of these potential pitfalls is failing to use all spins. Assuming that the player claims their free spins bonus and they fail to redeem all 100 of them, they will lose the unclaimed portion after the expiry date. This is an important thing to note for players who tend to use their spins sparingly — it might be a good strategy to keep their gambling hobby in check, but when it comes to free spins, it could cause them to lose the bonus.

Then, there is the wagering oversight, which tends to happen among new and inexperienced players who forget about the wagering requirement. In their excitement to withdraw their winnings, they rush to the withdrawal page and try to withdraw winnings that are still classified as bonus funds. Such premature withdrawal attempts will lead to forfeiture of their winnings, as the casino won’t allow it, and will reclaim the funds as the player breached the rules.

The same is likely to happen in the event of max bet violations. As mentioned earlier, casinos tend to impose limitations on how much the player can win and withdraw, but the same is true when it comes to betting the bonus funds. Max bet limits are often fairly low, usually £2 to £5 per spin. If the player attempts to bet more than that per spin or per round, it will result in forfeiture.

Finally, many players fail to do their ID verification early on, which then re-emerges as an obstacle when they meet other requirements and try to withdraw their funds. What happens is that they receive a notification that they cannot do so due to missing KYC. They might try to complete the KYC process then and there, but even after submitting their information, it will take time for the casino to verify it, and that may take long enough for time limits to expire, leading to the loss of all of the winnings.

Maximising the Value of 100 Free Spins

If you take free spins at face value, players might conclude that there is not much room for strategising. After all, slots revolve around pulling the lever and watching the symbols align and tell you whether you have won something or not. However, there are a few things that players can do to maximise the value of their 100 Free Spins.

The first thing to do is applicable in cases where the casino allows the player to use their free spins on multiple slots. If there is a choice, there is a chance to improve their odds of winning simply by researching the specific games and determining their volatility. Some slots are more volatile than others, and players who opt for low- or medium-volatility slots might see more consistent returns. 

High volatility slots may yield greater returns, and they might be particularly attractive with 100 free spins at the player’s disposal. However, players who want to play it safe will pursue any earnings, rather than potential great earnings, so this approach is worth considering.

Next, players should also abide by wagering, meaning that they should thoroughly read the T&C section of the platform to determine whether the requirement applies to bonus winnings only or to the funds they initially deposited to claim the bonus, as well.

Another way to determine a positive outcome is to play sooner, rather than later. In other words, free spins may only be available for a short time, so players should use them up quickly, instead of allowing them to expire. In a “use it or lose it” scenario, doing so is sensible.

Finally, players should use responsible gaming tools that casinos must offer under UK gambling laws. This is encouraged as a large number of free spins may prompt players to start making further deposits and lose themselves in the games, which could lead to financial problems. To prevent this, casinos offer tools like deposit limits, reality checks, and self-exclusion from their platforms, and players are highly encouraged to use them if they spot signs of problematic behaviour after their 100 free spins run out.

Comparing 100 Free Spins with Smaller or Larger Spin Sets

When it comes to free spin sets, 100 Free Spins significantly surpass what the players can do with smaller variations, like 10 free spins, 20 free spins, or 50 free spins offers. 100 Free Spins can let the player win more money, explore one or several slot games fairly well, and get a good feel for the platform they are using before they commit more money to it.

In comparison, these smaller spin sets feel too limited and can only provide a small taste of the platform before they expire, and the player has to decide whether to keep going with their own money or not, on an incomplete understanding of the platform and its games.

On the other hand, there are larger offers, such as 200, 300, or even 500 Free Spins, which might demand a considerably larger deposit or could come with more demanding conditions. With that said, 100 Free Spins might look generous at first, but it is really a mid-range offer — neither too limited nor too overwhelming. It offers just enough to strike a good balance between extended play and manageable T&Cs, making it worth exploring.

Responsible Gaming

While offers like 100 Free Spins do not require a major investment from the player’s side, as they are typically able to claim them with as little as £10 to £20, they still offer a full experience of the gambling thrill that games of chance tend to provide. As such, players could feel encouraged to deposit more money once the free spins are spent, and continue playing.

This is why the awareness of responsible gambling is important, as it is very easy to start spending large amounts of money on paying for more and more spins, convinced that the next one will double your winnings or let you reclaim your losses. To avoid this massive pitfall, players can do several things, such as keeping an eye on the bankroll and how quickly it is depleted.

To do this, players can set up deposit or loss limits that would disrupt their gameplay and let them know how much money they have used or lost to the games up to that point. Along the way, casinos also offer reality checks that can let the player know how much time they spent on the platform, which is also necessary, as gambling tends to make one lose track of time just as easily as money.

Players can also spend some time studying how odds and wagering requirements work to avoid being caught off-guard by terms like wagering requirements. Last, but not least, players who notice that they are losing control should use the time-out feature or a self-exclusion tool to limit their access to the platform. 

This tool can let them take a long break, or even bar themselves from accessing their account in the first place. If they believe there is a chance that they might look up similar games on other casinos, they can reach out to services like GambleAware and GamCare, which can help them by preventing them from accessing most other UK-licensed casinos. These services provide free, confidential help and guidance, and players who decide that they need help are always encouraged to reach out to them.

Main Takeaways

The 100 Free Spins bonus is one of the rarer bonuses on the UK gambling scene, but it can still be found with relative ease, especially as a deposit-based bonus for both newcomers to online casinos and as existing users. With 100 spins, players get to experience prolonged gameplay and check out one or even several slots, depending on the terms of the promotion.

Generally, this bonus can let the player experience all the benefits, features, and mechanics of the assigned slots, and decide whether these games — or the entire casino, for that matter — are a good match for them. 

With that said, players should also be aware that the 100 Free Spins bonus comes with certain terms and conditions, which may include wagering requirements, time limits, KYC verification, max win/withdrawal caps, and alike. Still, 100 free spins can provide a good opportunity to win a sizable amount, which typically overshadows smaller spin sets, like 10, 20, or even 50 free spins. However, players should also be aware of responsible gambling practices and use tools that casinos have left at their disposal for their own safety and the safety of their funds.

  • 100 Free Spins are typically a part of welcome bonuses and provide extended gameplay time
  • Most offers are deposit-based, and while no-deposit free spins exist, they are very rare and heavily restricted
  • While more flexible than no-deposit spins, deposit-based ones still come with wagering requirements, time limits, max bet caps, and more.
  • Players can maximise their winnings by studying how odds and wagering work, slot volatility, and making sure that they spend all the spins before they expire.
  • Players are recommended to use deposit and loss limit tools, self-exclusion tools, reality checks, and services like GambleAware and GamCare if they need help staying in control.
  • Make sure to read the T&C before claiming your 100 Free Spins to know what terms apply.

FAQs

Is it common for UK casinos to give 100 free spins as part of a welcome bonus?

While various free spin sets are commonly awarded to players as a welcome bonus, 100 Free Spins are not extremely common, but they can be found relatively easily on UK online casinos.

Are there any no-deposit deals offering 100 free spins, or do they generally require a deposit?

Players may find a no-deposit 100 Free Spins offer, but they are very rare, and most offers will be deposit-based.

How soon must I use up my 100 free spins before they expire?

This depends on the casino’s terms, but most platforms require the player to use them within 24 to 72 hours. In some cases, the offer may split the spins to use 20 per day over 5 days, or 10 per day over 10 days.

Do the spins always have wagering requirements on winnings, or can they be wager-free?

It is possible to find a wager-free offer, but this is also rare, and most offers will come with wagering requirements. Ultimately, it is up to the casinos to decide.

Are the spins usable on multiple games, or do they typically limit me to one title?

Many free spin deals tend to link their spins to a single game, but it is possible to find an offer that lets the player engage with multiple slots. This can vary from one casino to the next.

What if I forget to complete ID verification – can I still withdraw potential earnings?

No, under UK law, casinos are not allowed to let the player withdraw money without completing ID verification.

Why do some 100 free spins promotions cap my maximum withdrawable profit?

Casinos introduce a maximum withdrawal cap to reduce financial risks for themselves. As the free spins are essentially gift spins, casinos could stand to lose a lot of money if players abuse this promotion.

Are high-volatility games better or worse for meeting wagering requirements with 100 free spins?

High volatility slots can produce big wins, but they are less consistent and reliable. This makes them riskier for clearing wagering requirements, which is why most players use medium-volatility ones that offer a better balance.

How can I prevent overspending if I decide to deposit more after my free spins run out?

Set deposit limits and use reality checks to keep an eye on your gaming habits. Also, track your bankroll to stay in control of your spending.

Do I need a specific code to access the 100 free spins, or is it automatic once I register?

Depending on the offer, there might be a promo code or opt-in requirement, but in some cases, bonuses are triggered automatically after registration or a deposit.

Is there a maximum bet per spin once my winnings convert to bonus money?

Yes, bonus funds come with a max bet per spin that is usually between £2 and £5. Read the casino’s Terms & Conditions to know how much you are allowed to wager, and don’t go beyond that limit, as it would be considered a breach of the rules.

Can I forfeit the 100 free spins bonus if I do not want to fulfil the playthrough?

Yes, this is possible, and some platforms have an option that allows the player to do so, while others do not, and players must contact customer support in order to give up on their bonus in a controlled way.

May I claim multiple 100 free spins deals at different casinos in the same month?

Yes, as long as it is on different platforms, and not by using multiple accounts on the same platform. That is against the rules, and casinos are very strict about it, and will usually permanently ban the player.

Are 100 free spins more likely to result in bigger wins compared to 50 or 20 spin offers?

Statistically, yes. With more spins, the player has a greater chance of winning money, which ultimately translates to more money being won.

Does the UKGC place any special regulations on large free spin bundles like 100 spins?

No, all free spin offers are regulated in the same way, requiring all bonus terms to be clear and accessible. The spin amount does not change these obligations, nor does it include additional ones.
