Bonus buy in the UK

Bonus buy UK: the short answer

If you search for bonus buy UK slots, you won't find a UK-licensed casino that sells them. The slot versions supplied to Great Britain leave out the button that lets you pay, say, 100 times your stake to start the free spins feature at once. You reach the bonus the slow way: by landing the trigger symbols on a normal spin.

What there isn't is a neat headline rule. The Gambling Commission's published game design changes from 2021 deal with autoplay, spin speed, turbo and slam stops, and celebrating losses; they don't mention bonus buy or feature buy by name. So the accurate way to describe the position is that games are supplied to Great Britain without the option, not that a particular regulation switched it off on a particular day. Where a website gives you a ban date, treat that claim with caution.

This page describes how slots are supplied to UK players at 21 October 2026. It isn't legal advice. For the full set of online rules see our UK slot machine rules guide and the rules hub.

What a bonus buy (feature buy) is on an online slot

A bonus buy is a paid shortcut. Instead of spinning until three or more scatters land, you pay a fixed multiple of your base stake and the game starts the bonus round straight away. The price is set by the developer's maths team so that the expected value of the feature, divided by the price, roughly matches the game's advertised return. In other words, you are prepaying for the bonus at about its average worth, minus the house edge.

Bonus buys differ from an ante bet, which raises every spin's cost by a fixed percentage in return for a higher chance of triggering the feature naturally. They also differ from the gamble ladder on fruit machines, where you risk a win you've already landed. The table below sets these options side by side.

What the UK rules actually say about bonus buy

Three sets of official rules shape the UK version of any online slot. None of them names bonus buy, but each one matters for how a slot is built for Great Britain.

• Game design rules, since 31 October 2021. The Commission's summary of changes to the remote technical standards (opens in a new tab) requires each game cycle to be started individually (no autoplay), at least 2.5 seconds between game cycles, no turbo or slam stop, no celebration of a return equal to or less than the stake, and a visible net position and elapsed time.
• Stake limits, since 2025. The Commission's online slots stake limit guidance (opens in a new tab) sets £5 per game cycle for players aged 25 and over (from 9 April 2025) and £2 for those aged 18 to 24 (from 21 May 2025). It says further stakes made within a game cycle count towards the limit.
• Bonus rules, from 19 January 2026. Wagering on bonuses is capped at 10x and promotions that mix gambling products are banned.

Read together, the stake limit is the rule most relevant to a buy button. A buy is a stake: you hand over money for an outcome decided by the random number generator. On the Commission's definition of a game cycle, a buy priced at 100x would breach the £5 cap at any base stake above 5p, and the £2 cap for 18 to 24-year-olds above 2p. That is our reading of how the rules interact, not a statement from the Commission, but it shows why a buy option would sit awkwardly with UK limits even before the 2025 caps arrived.

Why UK-licensed casinos don't offer bonus buy

Studios usually build one core game and then produce versions for different markets. The UK build is configured to meet the remote technical standards (opens in a new tab): no autoplay, no quick spin, the 2.5-second minimum game cycle and the stake caps. In that build the buy button is simply absent. The developer's own UK game sheet or the casino's help screen will normally list the game's features, and you'll see that the purchase option is missing.

There are also sound player-protection reasons that line up with the Commission's wider aims. A buy compresses many spins' worth of spending into a single click, speeds up play and raises the size of each loss. The 2021 rules were designed to slow play down and make losses clearer; a feature that turns £20 into one decision runs the other way. You don't need a named rule to see why operators and studios leave it out of games aimed at British players.

How much a bonus buy costs: worked maths in pounds

The easiest way to see what a buy does is to compare it with ordinary spins. Assume a slot with a 96% return to player and a buy price of 100x the stake. That price is illustrative; real buy prices vary by game and aren't available on UK versions anyway.

The average cost is the same as 100 normal spins at the same stake, because the RTP is the same. What changes is time and volatility. At 2.5 seconds a spin, 100 normal spins take at least four minutes and give you dozens of small results along the way. A buy commits the full £20 in a single action, and the result depends entirely on how one bonus round plays out. Some rounds return a few pounds, a few return far more, and the average only emerges over thousands of buys. For more on why outcomes swing so widely, see slot volatility and standard deviation.

There's a second, quieter point. Outside Great Britain, developers' help screens sometimes quote a separate RTP for the buy feature, which may be slightly higher or lower than the base game. Either way, the house keeps its edge. A buy never turns a slot into a winning proposition; it just changes how quickly and in what shape you pay the house edge.

Who the UK position on bonus buy applies to

The position covers online slots offered to consumers in Great Britain by casinos holding a Gambling Commission remote licence. That includes every casino we list, such as Coral Casino and Ladbrokes Casino.

• Players in England, Scotland and Wales using a UK-licensed site get the UK version of each game, without a buy option.
• Players in Northern Ireland sit under separate gambling law; the Commission's rules are written for Great Britain. See our page on gaming machines in Northern Ireland.
• Land-based machines in pubs, arcades and casinos never had a bonus buy in the online sense. A fruit machine may offer features such as nudges and holds, which follow different land-based standards.
• Free-play demos at UK casinos are only available after age verification (since May 2019), and they mirror the UK version, so they won't show a buy button either.

How to check whether a UK slot has a bonus buy

You don't need to rely on a review. Every UK slot carries its own rules, and a couple of minutes in the game help screen tells you what the version in front of you does.

1. Open the slot at a UK-licensed casino and select the information or 'i' icon, usually beside the stake button.
2. Read the features list. On a UK build you'll see the trigger rules for free spins, but no section headed 'Buy feature', 'Bonus buy' or 'Feature buy'.
3. Find the RTP line. UK versions list one RTP for the game; a separate 'buy feature RTP' line would suggest a non-UK build.
4. Check the stake range. The maximum shown should not exceed £5 per spin, or £2 if your account shows you are aged 18 to 24.
5. Look for the time and net position display, which UK rules require during play.
6. If anything doesn't match, stop and check the operator's licence on the Commission register.

Our guide to finding a slot's RTP walks through the help screen in more detail, including why one casino may run a different RTP variant from another.

What the UK bonus buy position does not cover

Missing buy buttons get blamed for more than they should. The absence of bonus buy doesn't affect:

• Free spins features themselves, which still trigger naturally on UK slots and can still be retriggered where the game allows (retrigger rules).
• Free spins offers from casinos, which are promotions with their own terms, not purchases inside a game.
• Jackpots: progressive and fixed jackpots run as normal, within the stake limits.
• Feature odds: the natural trigger chance on the UK version is set by the developer's maths and shown, if at all, in the help screen; we don't quote trigger rates that aren't published. See odds of triggering a slot bonus.

Playing UK slots without bonus buy: where the offers fit

Because the buy button is missing, the only route into a slot's bonus at a UK casino is spinning, and that's what casino free spins offers pay for. They don't sell features; they give you a set number of spins at a fixed value on chosen games. Game lists change, so search each casino's lobby for the titles you want rather than assuming they're there.

Coral Casino offers new players aged 18+ 100 free spins when they deposit and bet £10 or more on slots between 1 October 2026 and 1 February 2027: the spins are worth 10p each on selected games, must be accepted within 48 hours and used within 7 days, and winnings carry no wagering. Ladbrokes Casino gives new customers aged 18+ up to 500 free spins after they deposit and spend £10 on slots, paid as 50 a day for 10 days at 10p each, claimed by 23:59 each day and valid for 7 days, again with no wagering. Some payment methods, including PayPal, Skrill, Neteller, Paysafe and prepaid cards, don't qualify. Both brands belong to LC International Limited (Entain), so you may not be able to take both; read the terms. 18+, terms apply. Our slot offers hub explains how free spins are valued.

18+. Gambling should be entertainment that costs money, not a way to make it. Decide a budget before you play: plan a slot budget. Free, confidential help: National Gambling Helpline 0808 8020 133.
