Bonus Buy Slots Not on GamStop — What UK Players Need to Know
If you have tried to find a “Buy Feature” button on a slot at any major UK casino recently, you already know it is not there. The UK Gambling Commission (UKGC) banned the bonus buy feature from all UKGC-licensed operators in October 2019, citing concerns that the mechanic encourages players to dramatically increase their stake — a direct breach of the Commission’s Remote Gambling and Software Technical Standards (RTS).
The result is that every UK-facing, GamStop-registered casino strips the feature before it ever reaches you. Gates of Olympus, Money Train 4, Sweet Bonanza — you can play all of them, but the “Buy Bonus” button is gone.
Non-GamStop casinos operating under offshore licences — from Curacao and similar jurisdictions — face no such restriction. Providers like Pragmatic Play, Relax Gaming, Hacksaw Gaming, Nolimit City, and Big Time Gaming supply the full version of their games to these platforms, with the bonus buy feature fully enabled. For players who know exactly what they are doing and are comfortable with the trade-offs, these are the only sites where the feature is accessible in 2026.
Why the UKGC Banned Bonus Buy Slots in the UK
The UKGC began issuing warnings to licensed operators in October 2019, directing them to disable bonus buy — also called “feature buy” or “buy bonus” — across their entire slot catalogues. The regulatory basis sits in clause 14a of the Remote Gambling and Software Technical Standards (RTS), which states that gambling products must not actively encourage customers to chase losses, increase their stake beyond what they have chosen, or continue gambling after they have indicated a wish to stop.
Bonus buy, in the Commission’s view, does precisely that: it invites a player to pay 50x, 100x, or even 500x their current stake in a single transaction in order to skip straight to the bonus round. That dramatic escalation of outlay — even if voluntary — was deemed incompatible with safer gambling principles.
The ban was notably swift. Unlike autoplay restrictions, which went through a public consultation period before implementation, the UKGC moved quickly on bonus buy, treating it as an open-and-shut breach of the existing RTS rather than requiring new rules.
In 2025 the regulatory environment tightened further. Online slot stake limits were introduced in two stages: a maximum of £5 per spin for players aged 25 and over (effective 9 April 2025) and a lower limit of £2 per spin for players aged 18 to 24 (effective 21 May 2025). These changes were confirmed by the UKGC and enacted through a Statutory Instrument amending the Gambling Act 2005. For UKGC-licensed sites, this means even the base game stakes are now capped — making the prospect of a 100x stake bonus buy on UKGC platforms even more remote.
Non-GamStop casinos are unaffected by either of these developments and continue to offer bonus buy without stake restrictions.
How Bonus Buy Works
Bonus buy — sometimes labelled “Feature Buy”, “Buy Bonus”, or simply “Buy” — is a mechanic that lets you skip the base game and jump directly into the slot’s main bonus round by paying a fixed multiplier of your current stake.
The cost varies substantially by game and by which tier of bonus you want. At the lower end, Money Train 4 by Relax Gaming offers an entry-level bonus buy for 20x your stake. At the higher end, San Quentin xWays by Nolimit City offers a premium Bonus Hunt option priced at 2,000x your stake. The most common price point across the industry is 100x the stake — so if you are playing at £1 per spin, the feature buy costs £100.
The mechanics are RNG-certified, which means the outcome of the bonus round you have just paid to enter is determined by a random number generator in exactly the same way as a bonus triggered organically. You are not guaranteed a win proportional to what you paid — you are paying to guarantee entry to the bonus round and to access the (typically) higher RTP that applies during that feature.
To put it in concrete terms: if you play Gates of Olympus by Pragmatic Play at a £0.50 stake and buy the bonus for 100x, you are spending £50 to immediately enter the free spins round. From there you might win £5 or you might win £2,500 — the RNG decides. The 100x cost also means your overall session RTP is measured differently than in standard play, as the cost is a sunk spend.
Understanding this distinction — paying for access, not paying for a profit — is essential before using the feature.
The 7 Best Bonus Buy Slots for Non-GamStop Players in 2026
Non-GamStop casinos carry the full catalogues of the world’s leading slot developers, which means every title below is available with its bonus buy feature intact. Here are the seven titles that consistently generate the most interest from players in 2026.
| Slot | Provider | Bonus Buy Cost | RTP | Max Win |
|---|---|---|---|---|
| Gates of Olympus | Pragmatic Play | 100x | 96.5% | 5,000x |
| Money Train 4 | Relax Gaming | 20x–500x | 96.1–97% | 150,000x |
| Wanted Dead or a Wild | Hacksaw Gaming | 80x–400x | 96.38% | 12,500x |
| San Quentin xWays | Nolimit City | 100x–2000x | 96.03% | 150,000x |
| White Rabbit Megaways | Big Time Gaming | 100x | 97.72% | 13,000x |
| The Hand of Anubis | Hacksaw Gaming | 129x–200x | 96.24% | 10,000x |
| Sweet Bonanza | Pragmatic Play | 100x | 96.48% | 21,100x |
Gates of Olympus (Pragmatic Play)
Gates of Olympus is arguably the slot that put bonus buy firmly on the map for mainstream players. Set across a 6×5 grid with tumbling reels and a multiplier system that can stack to 500x during free spins, the feature is where all the excitement lives. The bonus buy costs 100x your stake — at a £1 bet that is £100 — and delivers immediate access to a free spins round that can theoretically return up to 5,000x your stake. Pragmatic Play is one of the most respected providers in the industry, and the RTP here sits at a respectable 96.5%. This is a high-volatility title, so you should expect significant swings even after buying in.
Money Train 4 (Relax Gaming)
Relax Gaming’s Money Train series has been one of the most talked-about slot franchises of the last five years, and the fourth instalment raises the ceiling to an extraordinary 150,000x max win. The bonus buy structure is tiered: you can enter the Money Cart bonus for 100x your stake, or pay 500x to guarantee at least one persistent symbol from the start of the feature — which dramatically increases your expected value. A lower-tier entry option starts at approximately 20x stake depending on the operator’s configuration. With an RTP ranging from 96.1% on the standard version up to approximately 97% on the higher-tier buy options, this is one of the most mathematically compelling bonus buy games available.
Wanted Dead or a Wild (Hacksaw Gaming)
Hacksaw Gaming has established itself as one of the most innovative slot providers working today, and Wanted Dead or a Wild is a flagship title. The Wild West theme conceals a brutal volatility engine that can hit up to 12,500x. The bonus buy ranges from 80x (for a standard free spins entry) up to 400x for the premium version with additional wild modifiers pre-loaded. RTP is a solid 96.38%. If you prefer a slot that feels a little grittier and more unpredictable than the Greek mythology options, this is an excellent choice.
San Quentin xWays (Nolimit City)
San Quentin xWays by Nolimit City is one of the most extreme slots in existence. The dark prison-break theme is matched by an equally ruthless volatility profile, with a theoretical max win of 150,000x your stake. The bonus buy options span from 100x right up to 2,000x for the game’s most powerful starting configuration. Nolimit City builds multiple entry tiers into the feature buy, giving players genuine choice about how aggressively they want to enter. The base RTP of 96.03% is consistent with industry averages, but it is the sheer ceiling that draws high-volatility enthusiasts to this title.
White Rabbit Megaways (Big Time Gaming)
Big Time Gaming (BTG) invented the Megaways mechanic, and White Rabbit remains one of the most iconic titles in the company’s catalogue. With up to 248,832 ways to win and a feature trigger that involves extending the reels, the free spins round here is genuinely distinctive. The bonus buy is set at 100x your stake, and the slot’s RTP of 97.72% is notably above average — making it one of the better-value feature buys in terms of theoretical return. Max win sits at 13,000x. For players who appreciate the Megaways format and want a high-RTP title, White Rabbit is worth serious consideration.
The Hand of Anubis (Hacksaw Gaming)
Another Hacksaw Gaming title, The Hand of Anubis takes the developer’s signature sharp visual style into an Egyptian theme. Bonus buy options range from 129x to 200x your stake, placing it at the mid-range of the market in terms of entry cost. RTP of 96.24% is slightly below average but within normal parameters, and the 10,000x max win is a solid ceiling for a mid-volatility buy. This is a good option for players who want the Hacksaw Gaming experience but find Wanted Dead or a Wild a little too extreme for their session budget.
Sweet Bonanza (Pragmatic Play)
Sweet Bonanza is one of Pragmatic Play’s best-known titles globally, and its candy-coloured aesthetic belies some of the biggest potential multipliers in the Pragmatic library. The tumble mechanic during free spins can stack multipliers to enormous levels, and the 21,100x max win is among the highest in the Pragmatic catalogue. Bonus buy costs 100x your stake. The 96.48% RTP is solid, and the combination of recognisable brand, high max win, and straightforward buy mechanic makes this a perennial favourite at non-GamStop casinos for players who want a reliable entry point into feature buying.

Is Buying the Bonus Worth It? The Honest Answer
The honest answer is: it depends entirely on what you are optimising for.
The case for bonus buy. When you buy the bonus, you are purchasing certainty of experience. You know you are going to see the game’s main feature — the part that the slot was actually built around — without potentially grinding through hundreds of spins to get there. On high-volatility titles where the base game might go 400+ spins without triggering the feature, the bonus buy removes the single most frustrating aspect of the experience. Additionally, many providers configure the bonus buy version of the game with a marginally higher RTP than the base game, so in purely theoretical terms you may be getting slightly better value for your money during the feature itself.
The case against bonus buy. The cost is substantial. At the common 100x price point, buying the feature on a £1 stake costs £100. That is the same as 100 base game spins at £1 each — and in those 100 spins you might have triggered the feature naturally once or twice, potentially with a much lower net outlay. The feature buy also removes the natural rhythm of a session and concentrates your variance into a small number of high-cost events. A run of three or four feature buys that return less than their cost each time can deplete a session bankroll very quickly.
When it makes sense. Bonus buy is most rational when you want a specific experience quickly — you want to see the Money Train 4 Money Cart in action, for example — or when you are playing at a minimum stake (£0.10–£0.20) where the absolute cost of the feature buy is proportionate to your session budget. It is least rational when it represents a large percentage of your total available funds, or when you are chasing a specific outcome after a losing session.
In summary: treat bonus buy as a product you are purchasing — access to an experience — rather than a strategy for generating profit. The RNG does not care that you paid to enter.
Bonus Buy FAQs
Responsible Gambling
Bonus buy slots are high-stakes, high-variance products. The large upfront cost of each feature purchase means losses can accumulate quickly, and the excitement of entering the bonus round can make it easy to lose track of your session spend.
