Bonus-buy (also called feature-buy or buy-bonus) is the slot mechanic that lets you pay 50x to 500x your stake to skip the base game and trigger the bonus round directly. The UKGC prohibited the feature at all UKGC-licensed online casinos in late 2023 as part of a broader package of player-protection rules. UK players can still see the slots that originally shipped with bonus-buy, the buy button is just disabled.
The rule, in plain English
The UKGC's Remote Technical Standards (RTS) update in late 2023 added a prohibition on bonus-buy mechanics at all UKGC-licensed casinos. The rule applies to every game category (slots, instant games, live casino) though slots is where the mechanic was most common.
The standard is enforced at the operator level. Studios that distribute games to UKGC operators must ship UK-compliant builds with the buy-feature disabled. Most major studios maintain dual builds: a UK-compliant version and a standard version for other markets.
Why the UKGC banned it
The regulator's stated rationale focused on harm-reduction. Bonus-buy slots compress the financial variance of a slot session into single events at very high stake-per-spin equivalents. A £5-stake slot becomes a £500-or-more single bet when buying the bonus. The UKGC's research found that bonus-buy use correlated with problem-gambling indicators including chasing losses and elevated session deposit totals.
The regulator also flagged the mismatch between the headline base-game stake (which appears in operator marketing and player-facing affordability checks) and the actual financial commitment when buy-features were used. Bonus-buy use could push a player above affordability check thresholds in single-spin events that the operator's monitoring systems weren't tuned to detect.
What changed at UK casinos in late 2023
For UK-licensed players, the visible changes were:
- Buy-bonus buttons disappeared from every slot at every UKGC-licensed operator.
- Studios with deep bonus-buy catalogues (Nolimit City, Hacksaw Gaming, Push Gaming) shipped UK-specific game builds with the feature stripped.
- A small subset of slots (those whose entire mathematical balance depended on bonus-buy revenue) were withdrawn from UKGC operators entirely rather than re-engineered.
- Several lower-volatility 'bonus-only' titles disappeared from UK lobbies altogether.
Non-UK markets and the slot catalogue
Other regulated markets (Sweden, Malta, Romania, several US states) continued to permit bonus-buy mechanics with various restrictions. The Netherlands' KSA regulator imposed a similar prohibition shortly after the UKGC. Germany's joint state regulator restricts but doesn't fully prohibit. The trend across Europe is toward restriction rather than removal.
UK players occasionally encounter operators offering 'buy bonus equivalents', turbo modes, ante-bet features that increase bonus trigger probability for higher stakes. These are not the same as bonus-buy under UKGC's definition; they remain permitted because they don't pre-commit a fixed bonus-round purchase.
Alternatives for high-volatility play
UK players seeking the bonus-buy experience legally have a few options:
- Ante-bet slots (increase the spin stake by typically 25% to double the bonus trigger probability. Permitted under UKGC rules; available at most major operators.
- High-volatility base-game play) Nolimit City and Hacksaw titles in their UK builds remain extremely high variance. The free spins or pick-and-win, triggered by scatter symbols.">bonus round still triggers; you just have to wait for it.
- Megaways slots from Big Time Gaming, the headline mechanic produces large hits in base game, no bonus-buy required.
For players who specifically valued the time-compression of bonus-buy (one decisive event per buy versus 100+ spins of waiting), there is no UK-licensed equivalent. The mechanic is gone from the UK market and unlikely to return.
