Bonus buy features

What a feature buy-in is

A feature buy-in—sometimes labelled “buy bonus” or “feature drop”—lets a player skip the base-game spins and purchase entry to the free-spins round or a similar bonus feature. The cost is set by the game’s maths. It can run to a few pounds, or, as the Commission discovered, thousands. The mechanic is visually simple: a button on the main game screen displays a fixed price; tap it, the stake is deducted from the balance, and the bonus starts. No waiting. No spin-by-spin accumulation of scatter symbols.

For players chasing the high-volatility thrill of a bonus round, the appeal is obvious. The risk, from a regulatory perspective, is less obvious to the player but was not lost on the Commission. Paying upfront to enter a bonus collapses the time that normally separates a decision to play and the delivery of the game’s most intense moment. That compression, the regulator argued, creates hazards that British rules were not built to absorb.

The 17 January 2020 warning and what followed

The Commission’s warning carried a blunt headline: “Games warning for online operators.” It noted that officials had identified six licensees offering slots with feature buy-in facilities. No operator names were released. No game titles were given. The one figure that cut through was the price of the most expensive buy-in among the batch: more than £3,000 for a single bonus entry.

That number is worth pausing on. A slot spin under UK rules at the time was already subject to transparency requirements, but nothing prevented a game from setting the bonus-entry cost at a level that would empty a weekly wage in seconds. The Commission did not argue the figure was illegal; it argued the very structure of the mechanic, when combined with that pricing, was incompatible with two technical standards operators must meet.

All six operators pulled the feature after being contacted. The removal was not the result of litigation or a fine. It was compliance by letter and by phone. Months later, a CMS legal update on the episode noted the Commission had cited two remote technical standards—RTS 3A and RTS 14A—without specifying which one the feature had breached. It pointed at both.

The two standards the Commission pointed at

RTS 3A concerns rules transparency. Operators must make an explanation of the applicable rules easily available to the customer before they commit to gamble. That explanation has to be accurate, sufficient to cover all the rules and how to participate, and all reasonable steps must be taken to ensure it is understandable. A £3,000 button that says “buy bonus” and drops the player into a feature with no further on-screen qualification raised questions about whether the rule set was genuinely understandable before the money left the account.

RTS 14A is the loss-chasing and stake-increase standard. It says products may not actively encourage customers to chase their losses, increase their stake or the amount they have decided to gamble, or continue to gamble after indicating they wish to stop. A feature that allows a player, after a losing run of base-game spins, to purchase a bonus round without waiting could be seen as a mechanism that facilitates exactly that kind of accelerated decision-making. The Commission did not say this explicitly; the two standards were quoted together, leaving operators to draw their own conclusions. They drew them fast.

A warning is not a statute, and why the result is the same

No British law has ever said “feature buy-in slots are prohibited.” The Commission published a warning under its existing powers, pointing at technical standards operators must comply with to hold a licence. The difference matters because a statutory ban would require primary legislation or a statutory instrument debated in Parliament. A licence condition applied through a warning carries the same practical force—breach it and you lose your permission to trade—but it sits in a regulatory grey space that is easier to challenge on paper. In practice, no operator did challenge it. The six removed the feature and the rest of the market followed, not because a court told them to, but because the cost of being wrong was existential.

That is why British lobbies look different from those in jurisdictions where the same game still offers a buy-bonus button. The underlying maths and the game files may be identical. The button is simply switched off for UK players by the platform’s compliance logic. The result is the same as a prohibition, but the legal instrument that achieved it was a warning, not a statute.

How the stake limit closes the door further

From 9 April 2025 the economics of any future bonus buy-in attempt shifted again. A new per-game-cycle stake limit, introduced through The Gambling Act 2005 (Operating Licence Conditions) (Amendment) Regulations 2025, caps an online slot player’s total stake per game cycle at £5 for anyone aged 25 or over. For under-25s the limit drops to £2 from 21 May 2025.

A game cycle includes the entire sequence from stake to outcome, so a bonus buy that charged a separate price would have to fit within that ceiling. A £5 maximum makes a £3,000 buy-in unthinkable, and even a modest buy-in of £10 or £20 is now impossible for licensed online slots in Great Britain. The combination of the 2020 warning and the 2025 stake limit erects two independent barriers: one rooted in transparency and safer-gambling standards, the other in a hard financial cap. Neither law names feature buy-ins. Together they make the button unworkable.
