If you’ve played slots for any length of time, you know the feeling. You’re sitting in the base game of Gates of Olympus, watching the Zeus multipliers build, spin after spin, chasing that bonus trigger. Sometimes it comes in five spins. Sometimes you’re 200 spins deep and still waiting. That variance can be genuinely exhausting.
Bonus buy features were designed for exactly this. Pay a fixed amount — usually 100x your stake — and you skip straight to the free spins. The feature’s yours, guaranteed. UKGC casinos banned them in 2021. Non-GamStop casinos didn’t. Here’s everything you need to know.
How Bonus Buy Features Work
The mechanics are straightforward. Every eligible slot has a “Buy Feature” or “Bonus Buy” button — sometimes labelled “Feature Buy” or “Ante Bet.” Click it, confirm the cost (which is displayed as a multiplier of your current stake), and you’re taken immediately to the free spins round or equivalent bonus feature.
The cost varies by slot:
- Gates of Olympus — 100x stake
- Sweet Bonanza — 100x stake
- Mental (Nolimit City) — 200x stake
- Deadwood (Nolimit City) — 100x stake
- The Dog House Megaways slots — 90x stake
- Razor Shark — 100x stake
- Wolf Gold — 25x stake
Importantly: slots RTP doesn’t change when you buy the bonus. You’re not getting better odds. What you’re buying is the removal of trigger variance — certainty that you’re in the bonus, right now, without the base game lottery. That distinction matters.
Why UKGC Banned Them (and Why Non-GamStop Sites Didn’t)
The UKGC ruled in 2021 that bonus buy features “speed up play” in ways that increase gambling harm risk. The argument is that the base game acts as a natural break in pace, and bypassing it removes that friction.
Offshore regulators took a different view. Curaçao and MGA-licensed casinos continued to offer the full versions of these slots, including the buy feature. So while UK players on UKGC sites see a greyed-out button or no button at all, players on non-GamStop sites have full access.
It’s a genuinely interesting regulatory split. I think reasonable people can disagree about whether the ban is proportionate — but the practical reality is clear: if you want to play bonus buy slots, you’re going to a non-GamStop casino.
The Best Bonus Buy Slots Available in 2026
Gates of Olympus (Pragmatic Play)
The one everyone knows. 96.5% RTP, 15 free spins, tumbling reels, and those Zeus multipliers that can stack to absurd levels. The 100x stake buy-in makes it accessible at most bet sizes. The potential is enormous — max win is 5,000x — but you need the multipliers to cooperate. From my experience, the buy is worth it if you want to see the feature without grinding through potentially hundreds of base game spins.
Sweet Bonanza (Pragmatic Play)
Candy-themed, cluster-pays, 100x stake bonus buy. The free spins include a bomb feature that plants multipliers (2x–100x) on the reel. When multiple multipliers land simultaneously, they add together, not multiply — which some players find disappointing compared to Gates, but the visual spectacle and hit frequency in the bonus keep it enormously popular.
Mental (Nolimit City)
This one’s for high-variance seekers. Mental has a 200x stake buy-in and a max win of 70,000x your stake. The theme is dark (it’s set inside a mental institution) and the volatility is brutal — you can buy the bonus and get a modest 30x return, or you can land in one of the escalating bonus modes that can produce monster wins. Not for the faint-hearted.
Deadwood (Nolimit City)
More accessible than Mental, but still Nolimit City’s signature extreme volatility. 100x stake buy, Western theme, a free spins round with sticky wilds that builds nicely. One of the better value bonus buys in terms of consistent entertainment — though “consistent” is relative when you’re talking about Nolimit.
The Dog House Megaways (Pragmatic Play)
90x stake buy-in — cheaper than most. Megaways mechanic means up to 117,649 ways to win. The free spins feature includes multiplier wilds and the option to re-trigger. Good for players who want more spins for their money rather than pure all-or-nothing variance.
Razor Shark (Push Gaming)
A slot that divides opinion but has a dedicated following. The Nudge and Respin feature in the base game is genuinely entertaining, and the free spins with respins can produce big wins when the shark tank fills with multipliers. 100x stake. Solid.
| Slot | Provider | RTP | Buy Cost | Max Win | Volatility |
|---|---|---|---|---|---|
| Gates of Olympus | Pragmatic Play | 96.5% | 100x stake | 5,000x | High |
| Sweet Bonanza | Pragmatic Play | 96.51% | 100x stake | 21,175x | High |
| Mental | Nolimit City | 96.08% | 200x stake | 70,000x | Extreme |
| Deadwood | Nolimit City | 96.35% | 100x stake | 16,150x | Very High |
| Dog House Megaways | Pragmatic Play | 96.55% | 90x stake | 12,305x | High |
| Razor Shark | Push Gaming | 96.7% | 100x stake | 50,000x | High |
Where to Play Bonus Buy Slots Not on GamStop
Not every non-GamStop casino has all of these titles — game libraries vary based on software provider deals. When you’re choosing a site, check that they carry the providers you want (Pragmatic Play, Nolimit City, Push Gaming) and that the bonus buy button is actually enabled, not just present.
A few other things I’d look at:
- Minimum stake. If the minimum bet is £0.20 and you’re buying at 100x, that’s a £20 minimum bonus buy. Some high-roller sites have higher minimums.
- Bonus terms. If you’re playing on a welcome bonus, bonus buy features are typically excluded from wagering. Read the T&Cs.
- Game loading speed. On high-volatility slots where you might do 10–15 buys in a session, slow loading between spins gets very irritating.

Frequently Asked Questions
What is a bonus buy feature in slots?
A bonus buy (also called feature buy or ante bet) lets you pay a fixed multiplier of your base stake — typically 50x to 200x — to go directly to the bonus round of a slot, skipping the base game entirely.
Why are bonus buy slots banned in the UK?
The UK Gambling Commission banned bonus buy features in October 2021, citing concerns that they accelerate gameplay and increase the risk of problem gambling. UKGC-licensed casinos cannot offer them.
Are bonus buy slots available at non-GamStop casinos?
Yes. Non-GamStop casinos operating under offshore licences (Curaçao, MGA) are not bound by UKGC rules, so they can offer the full version of slots including bonus buy features.
Is it worth buying the bonus on slots?
It depends on the slot and your goals. Bonus buys don’t change the RTP — you’re still playing a negative-expected-value game long-term. What they do is remove the variance of waiting for a trigger. You pay for certainty of entering the feature, not for better odds.
Which slot has the best bonus buy value?
Gates of Olympus (100x stake) and Sweet Bonanza (100x stake) are popular for their accessible buy-in prices and high-volatility bonus rounds with big multiplier potential. Mental by Nolimit City is favoured by high-rollers for extreme variance.
