Bonus Buy Slots

Slots where you can buy or upgrade the bonus round!

Bonus buy slots allow you to buy into the bonus round for an increased stake. In this article, we explain how the bonus buy feature works and introduce you to the best slots that give you instant or improved access to the bonus round!

When it comes to most slot games, there’s one thing we all look forward to: and that is the bonus round! Whether it’s a free spins round or a different kind of bonus game, this is typically where the biggest wins or jackpots are to be had.

However, there is a bit of bad news for all British players – since 2019, the UK Gambling Commission (UKGC) has declared it illegal for players players with a UK account to play slots with a bonus buy feature. This is due to reasons related to responsible gambling. As a result, providers have to offer the same games without this feature to UK players. 

That said, some providers have come up with alternative ways to helping you access the bonus round or get your hands on various feature upgrades, as we will discuss below in this article.

What Exactly is a Slot with a Bonus Buy Feature?

The Bonus Buy feature is exactly what it sounds like – the option to pay in order to go directly to the slot’s bonus feature, instead of randomly triggering it by playing the game. This feature first came about in 2017, when Big Time Gaming launched ihe slot White Rabbit Megaways. The idea is that you will pay a certain price in the hope of winning more through the combination of features you can enjoy during the bonus round.

UK players cannot take advantage of a Bonus Buy feature, but some providers offer an Ante-bet or Big Bet feature in their games. This allows players to increase their bet (usually by around 25%) for an increased chance to trigger the bonus round. Other games also allow one to gamble the bonus round for a chance to get more free spins or to pay for an upgrade of the feature once it’s triggered. In these cases the bonus round is not 100% guaranteed, and as such these are legal for UK players.

How Does the Bonus Buy Feature Work?

While playing the game as normally intended, you generally can trigger the bonus round by landing 3 or more scatter symbols on the reels. The bonus buy option has you skip this process by paying a premium to trigger the special round on the next spin. This can be handy, since the bonus round tends to offer the best payouts. 

How Much Does it Cost to Buy a Slot Bonus Round?

The cost for the bonus buy fee differs from between games, but can range from 50x the bet to as high as 270x your stake, if not more. For example, NetEnt’s Serengeti Kings has a costly bonus buy feature of 358x the stake, but this will trigger the bonus feature with a maximum of 5 scatters. However players can go for cheaper options that trigger the bonus round with 3 or 4 scatters. 

Buying a bonus round – Pros and Cons


The bonus buy option helps you skp the boring base game spins where nothing much happens. Instead, it takes you straight to the action, where you have a better chance of winning a potentially big win. 

The feature is particularly attractive in the case of slots where the bonus round is especially hard to trigger. One can argue that with such slots it’s cheaper to go for the bonus buy instead of trying to trigger the round the traditional way.


Paying for the bonus round is expensive, and you risk running out of funds or, worse, grossly overspending, if you avail yourself of this feature constanty.

Buying into the bonus round does not necessarily mean you are going to win big. In the end of the day, just like a normal bonus round, you can either win big or end the feature with just a small payout that does not exceed the price of the bonus buy-in. 

Tips on how to use the bonus buy round

Before buying the bonus round, it’s wise to do your research.

1. Check the bonus frequency

It may not be worthwhile buying the bonus round if the bonus frequency of a slot is good. In this case, it’s worth playing a few base game spins and triggering it in the traditional way.

The best way to check the bonus frequency of a slot game is by using Slot Tracker. This tool will let you know how often the bonus game is triggered on any particular slot.

2. Analyse how rewarding the bonus round is

It’s wise playing a slot game in demo mode to get an idea of how potentially rewarding the free spins or bonus round can be.

This will help you decide whether it’s worth buying the bonus in the hope of getting a big win, or whether you’re likely to make a loss if you do so.

3. Know when to quit using the feature

The bonus buy feature may tempt players to use it more often than they should.

If you find that you have made a loss from this feature a couple of times, it’s wise not to keep using it.

Having a budget that you’d like to use up on the feature, or a loss limit on it, will help you manage your bankroll better.

Complete list of games with a bonus buy-in option

Below we have provided you with a list of online slots that (outside of the UK) feature the bonus buy option.

As a British player, you can still enjoy any of the below games, however, you will have to go old school and wait for the scatter to trigger the bonus round! 

Are Bonus Buy Slots Legal in the UK?

Unfortunately, in 2019 the Gambling Commission has decided to make the bonus buy feature illegal for players with a UK account. For this reason, providers have continued to offer the same games without this feature to UK players. However, some providers have come up with an alternative way of helping you access the bonus round or get various feature upgrades, which we’ll discuss down below.

What are Feature Buy Slots?

Instead of allowing you to buy in to the bonus, some slot games allow you to pay for an extra feature or for an increased chance of triggering a feature. This type of feature buy slots do not guarantee that you’ll get into a bonus, but may help you do so (for example, by adding an extra scatter to the reels).

In some games, this option is known as an Ante-bet feature or a Big Bet feature. For a higher stake, UK players still get an increased chance of triggering the bonus round. Other games also allow you to gamble the bonus round for a chance to get more free spins, or to buy an upgrade once you trigger the bonus round!

The Big Bet feature is a great alternative to the Feature Buy for UK players

As long as the bonus round is not 100% guaranteed, these features are still legal for UK players, and there are several slots that offer them. Here are some examples of feature buy slots:

Which one is better: Bonus buy or Feature Buy?

There is one advantage to a bonus buy option: it guarantees you entry into the bonus round. However, the bonus buy tends to be much more expensive when compared to a single feature buy. Not to mention that UK players cannot benefit from it at the moment. For example, it would typically cost you 100x your stake to buy into the bonus directly in a Pragmatic Play slot that incorporates this option. However, if you use the ante bet feature in the same slot, this will only cost you 25% more on top of your bet.

The feature buy can be a gamble (and in fact, in some slots it is called a ‘gamble feature’ for this very reason). However, if you use it sparsely things can get less expensive than if you were to use the full bonus buy.

Great alternatives to Bonus Buy Slots

If you love bonus buy slots but you can’t play them in the UK, then you still have some other great options. In addition to the feature buy slots we looked at above, you might also look at some slots with great bonus features.

1. Slots with different bonus game options

Some slot games allow you to choose your desired level of volatility once you trigger the free spins round. One such example is NetEnt’s Dead or Alive 2, which comes with 3 different free spins modes to choose from. The High Noon Saloon spins come with a 15x multiplier and the potential of winning 100,000x your stake, but it’s also the most volatile round of the 3!

2. Slots with easy-to-trigger bonus games

Look for slots whose bonus game isn’t too hard to trigger. A look at the bonus hit frequency on slot reviews or tools like Slot Tracker can provide such an indication, as can playing the game in demo mode.

One of our top recommendations is NetEnt’s original Blood Suckers. We tend to trigger the pick and click bonus game quite often as we play it (and always end up winning decent cash prizes!) The game is also well known for its high RTP of 98%!

3. Slots with multi-level bonuses

Some slot games come with lengthier bonus rounds that allow you to progress through different levels for a chance to win bigger and bigger prizes. In Hugo 2, for example, players will first access the free spins round. From this round, they can also trigger the Skull Cavern bonus feature. If they manage to progress through this round without losing all of Hugo’s live, they can progress to the Treasure Chamber and win big! Avalon II is another example of a game with a fascinating multi-level bonus which also has a story to it. On your quest for the holy grail, you can unlock a succession of features. These includes more free spins, pick and click bonuses and a wheel of fortune at the very end!

4. Slots with highly rewarding bonus rounds

Not all bonus rounds were created equal. Some are simply not worth the wait. The idea is to look for those slots whose bonus rounds can be very rewarding, either due to a jackpot, or due to a combination of features that increase your chances of landing a big win.

Nowadays, there are plenty of bonus games that incorporate additional features like extra wilds and progressive multipliers. These include Play N Go’s Viking Runecraft (which comes with a 15x multiplier) and IGT’s Cleopatra Slot, where all your wins from the free spins round are tripled!

The providers behind the best Bonus Buy Slots

NetEnt hardly need an introduction. They are behind some of the most famous online slots, like Starburst, Gonzo’s Quest and Twin Spin.

Nowadays, UK players cannot benefit from the feature drop in slots by Big Time Gaming, but this doesn’t make the collection of games any less attractive: Slots like Extra Chilli Megaways and Monopoly Megaways have become hugely popular!

NextGen Gaming

NextGen Gaming is a studio with a history that dates back to 1999, and which has released hundreds of slot games.The provider has its small share of bonus buy slots.

Other bonus buy slots by NextGen Gaming include Medusa Megaways and Pillars of Asgard.
