What is a Bonus Buy?
A bonus buy – sometimes called a feature buy or buy bonus – is an in-game button that lets you pay a set multiple of your stake to trigger the bonus round immediately, rather than waiting for it to land naturally through the base game.
In a standard slot, you’d spin until scatter symbols land and open free spins. A bonus buy skips that entirely, and basically acts as a shortcut or fast pass into the free spins – aka the main event.
You pay the cost, the bonus starts, and you go straight to the part most players are there for – and where the maximum win multiplier often lies.
The price of a slot bonus buy varies by game and studio. Most sit between 50x and 100x stake — pay £1/€1 a spin and you’re paying £/€50–£/€100. Some extreme-variance titles go further: 200x or 500x your bet.
That makes the decision significant in a single click, which is exactly why the UK regulator took issue with it…
Are Bonus Buy Slots Available in the UK?
The short answer is no.
While you can still play slots with bonus buys in the UK, the actual feature buy option itself will be disabled, greyed out, or simply not there.
The UK Gambling Commission took action against feature-buy mechanics in 2019, raising concerns about players spending large amounts to access bonus rounds instantly.
As a result, UK-licensed operators were instructed to remove these features from their games.
UK players must trigger free spins and other bonus features naturally through regular gameplay.
Some free demo versions may still display Bonus Buy options, depending on the version being offered.
While you can enjoy many of the same games, buying your way into a bonus round isn’t an option at UK-licensed casinos.

Where to Play Bonus Buy Slots
Bonus buy slots are available in many regulated gambling markets around the world, although the rules vary between jurisdictions.
The UK is one notable exception, with the UK Gambling Commission outright banning the feature-buy mechanic at licensed online casinos.
However, that doesn’t mean UK players have to miss out on the games themselves! Some of the best bonus buy slots from providers such as Nolimit City, Relax Gaming, and Pragmatic Play are still available at UK casinos, just without the option to purchase bonus rounds directly.
Instead, you’ll need to trigger free spins and other features through regular gameplay, by collecting scatters or tokens.
Below, we’ve highlighted some UK-licensed online casinos where you can find popular feature-buy slot games, even if the bonus buy button itself is off-limits.
Gamble Responsibly with Bonus Buy Slots
Bonus buys are quite risky, with some feature purchases costing hundreds or even thousands of times your original stake, which is taken immediately after confirmation.
And while paying to enter a slot’s bonus round might seem like a shortcut into bigger payouts, there’s no guarantee you’ll win back the cost of the purchase, leaving you out of pocket.
If you’re playing in a jurisdiction where bonus buys are permitted, always check the purchase price, understand the game’s volatility, and set a firm budget before playing.
Avoid chasing losses or assuming that an expensive bonus is more likely to deliver a profitable result – make use of the casino’s responsible gambling tools and resources and never gamble more than you can accord to lose. You can find more information on our Responsible Gambling page.
Feature Buy Slots – FAQs
-
What are bonus buy slots?
Bonus buy slots, also known as feature buy slots, let players pay a fixed amount to trigger a bonus round instantly instead of waiting to unlock it through regular spins. These features are only available in markets where they’re permitted. -
Are bonus buy slots legal in the UK?
The games themselves can be available in the UK, but purchasing bonus features isn’t permitted at UKGC-licensed casinos. Players can still trigger free spins and other bonus rounds through normal gameplay, with no immediate shortcuts into bous rounds. -
Where can UK players play bonus buy slots?
UK players can play slots with feature buys at licensed UK casinos, but the bonus buy option will be disabled and unavailable. -
How much does it cost to buy a slot bonus?
Prices vary between games and providers. Some cost around 50x–100x your base stake, while more expensive options can cost hundreds or even thousands of times your bet. The purchase price doesn’t guarantee a profitable bonus round. -
Can I play bonus buy slots for free?
Yes, some free slot demos include bonus buy features, allowing you to explore their mechanics without spending real money. However, demo availability varies, and these options may be disabled in UK-specific versions. -
Do feature buy slots offer better value?
It’s hard to say, as the slot’s result is still down to RNG and luck. Bonus buy slots are as much of a gamble as regular slots – buying a bonus doesn’t guarantee results or big wins. -
Do bonus buy slots have a higher RTP?
Not necessarily. Some slots have different RTP settings for their bonus buy and regular gameplay modes, but purchasing a feature doesn’t automatically guarantee a higher theoretical return. Always check the game’s information screen for the relevant RTP. -
What’s the difference between bonus buy and ante bet?
Bonus buy lets players pay to trigger a feature immediately, while ante bet usually increases the stake in exchange for a higher chance of triggering certain features during normal gameplay. The two mechanics work differently, and their availability depends on local regulations.
Are Bonus Buy Slots Worth It?
Whether bonus buy slots are worth it comes down to what you enjoy the most about playing slots in the first place.
If you prefer the excitement and win potential of free spins, it’s easy to see why the option to shortcut straight into action has become so popular.
However, bonus buy features are restricted in certain jurisdictions, including the UK, due to concerns about their predatory nature and risks of excessive gambling. Paying large amounts to access bonus rounds instantly can encourage players to spend more than they intended.
Buying a bonus doesn’t guarantee a big win, and some feature purchases can cost hundreds or even thousands of times your stake.
While certain games offer different, often increased, RTP settings for bonus buy modes, that doesn’t mean you’re guaranteed better returns by default. In fact, we’ve had many occasions on stream where an expensive bonus round can be over in seconds with very little to show for it!
Before buying a bonus, we’d strongly recommend weighting up the risks, considering whether you can comfortably afford the cost, and deciding if the entertainment is worth the money.
We’d also recommend reading our slot reviews and trying the games in demo mode first to get a better understanding of their mechanics and bonus features before risking real money.
