Bonus Buys: What They Cost and Why Some Countries Banned Them

What you are actually buying

A bonus buy, or feature buy, lets you pay a fixed price to enter a slot's bonus round immediately rather than waiting for it to trigger. The price is typically 60 to 100 times the stake, and it is displayed as a button beside the reels.

What the money buys is certainty of entry. It does not buy better odds. Studios publish an RTP for the buy alongside the base game figure, and the two are usually within a fraction of a percentage point of each other. You are not getting a better deal by paying to skip the wait; you are getting the same deal, faster.

The arithmetic that actually changes

What does change, and changes enormously, is your exposure per decision. A player staking one unit per spin who buys an 80x feature has just staked eighty units on a single outcome. The bankroll that would have lasted two hundred spins now lasts two and a half purchases.

This is the part that gets lost in the RTP comparison. Two players can face identical published returns and have completely different experiences, because one of them is making a decision every three seconds at one unit and the other is making a decision every thirty seconds at eighty. The long-run average is the same. The time to reach it, and the variance along the way, are not remotely the same.

Why regulators intervened

The United Kingdom, the Netherlands and several other regulated markets have prohibited bonus buys outright. The reasoning was not that the odds were misrepresented, because they were not. It was about structure.

The wait between bonus rounds is a natural brake. It is dead time during which a session can end, a player can get bored, or a decision can be reconsidered. Removing it removes the pause, and multiplying the stake at the same moment removes the small size of each mistake. Regulators treated that combination as a structural risk rather than a matter of player preference, which is why the response was a ban rather than a warning label.

What this means when you read a game page

The same slot behaves differently depending on which licence you are playing under. A title listed with a feature buy on one site will simply not show that button on a UK-licensed casino, and the game is otherwise identical.

This matters when comparing reviews. A review that mentions the buy without naming the jurisdiction is describing a version of the game that may not be available to you, and a review that omits it may simply have been written in a market where it does not exist. Where this site lists a feature buy, it is because the studio publishes one for the title, not because any particular casino offers it.

If the option is in front of you

Two things are worth knowing before pressing it. First, the published RTP for the buy is the honest comparison point, and if a casino does not show it, the studio's own information panel will. Second, the price is per attempt and the bonus round can and frequently does return less than it cost — a bought round is not a guaranteed profit, it is a guaranteed entry.

The option exists because it sells. That is a sufficient explanation for its presence and not a reason to use it.

The short version

A bonus buy costs 60 to 100 times the stake, does not improve the published return, and multiplies how much you risk on each decision by the same factor. Several regulators banned it on that basis alone. If you play in a market where it exists, the figure worth checking is the RTP stated for the buy, and the figure worth remembering is how many spins the same money would otherwise have lasted.
