What Are Bonus Buy Slots and How Do They Work?
Bonus buy slots let you skip the base game and pay a fixed price to trigger a feature immediately. Instead of spinning through hundreds of dead rounds waiting for three scatters to land, you select the “Buy Feature” button and the game jumps straight to free spins, a pick-me bonus, or a multiplier round. The mechanic was popularised by developers such as Big Time Gaming and Nolimit City, and it now appears across a huge share of new UK-facing releases.

The purchase price is usually expressed as a multiple of your current stake. Common options sit between 40x and 100x, while premium features , enhanced volatility versions with extra wilds or guaranteed multipliers , can cost 200x, 500x or even 1,000x your bet. On a 20p stake, a standard 100x buy therefore costs £20, whereas the same purchase at £2 per spin sets you back £200.
It helps to understand the maths behind the button. The buy price is calibrated against the feature’s theoretical return, so triggering it directly carries the same RTP as playing towards it organically , typically somewhere between 94% and 97%. What changes is variance. You trade the slow grind of the base game for a single, all-or-nothing shot at a big win, which is why bonus buys appeal to players who value pace over patience.
Reputable providers publish the buy price, the RTP of the purchased feature and the maximum win in the game’s paytable. Always check these figures before committing, because a 500x purchase on a 94% RTP game means the average return on a £100 buy is £94 across millions of simulated purchases , not on your single attempt.
Are Bonus Buys Legal and Available to UK Players?
This is where the UK market differs sharply from many others. The Gambling Commission has taken a firm line on feature purchases, and since late 2020 bonus buy functionality has been prohibited for slots offered to British players. Licensed operators cannot present a direct “pay to enter the bonus” button as part of the base game.
What you will find instead are workarounds. Some titles let you accumulate a feature-spin meter that is funded by a higher stake per spin, while others offer “ante bet” variants that raise your wager by 25% to 50% in exchange for a greater chance of triggering free spins naturally. These are permitted because the outcome is still determined by the reels rather than a direct purchase.
The regulator’s rationale centres on harm reduction. A single click that costs 100x your stake compresses a large loss into seconds, undermining the staking limits and session reminders that apply to standard play. Under the current rules, online slots must also cap spin speed and display net session position, measures designed to slow decision-making.
Players accessing sites licensed elsewhere may still encounter genuine buy buttons, but those operators are not regulated by the Commission and offer no protection under UK consumer law. For anyone staking in GBP with a British-licensed brand, the honest answer is that the classic bonus buy is unavailable , and the alternatives described above are what you should look for.
How to Approach Feature Purchases Responsibly
Whether you are using an ante-bet variant or playing a demo version with a buy button, the same principles apply. Set a hard budget for the session before you start, and treat each purchase as a single bet rather than an investment. A 100x buy at £1 per spin costs £100 , that is a substantial wager, not a shortcut.
Check the maximum win and volatility rating first. Highly volatile features can return nothing at all on a majority of purchases, which is precisely why the potential payout is so large. Compare the buy price against your average stake and ask whether ten standard spins would deliver better entertainment value for the same money.
Finally, use the tools every UK-licensed site must provide: deposit limits, loss limits, reality checks and self-exclusion via GAMSTOP. If feature purchases feel less like entertainment and more like a chase, step away. The best bonus is the one you can comfortably afford to lose.
