Paying up front to skip to the feature round — and what that decision is worth.
A buy button hands the studio a multiple of your stake and starts the feature round immediately instead of making you wait for it to trigger. The price is set so the game keeps its margin, and some titles rebalance the round itself when it is bought rather than earned. Two things are worth knowing before you press it. The buy counts as a single bet, so it can run straight into a maximum stake rule while a bonus is active. And a fair number of casinos leave bought features out of wagering contribution entirely. The bonus terms decide that, not the game.
We are not naming games on this page. Our records carry the phrase in the old page addresses of two slots, and an old address of ours proves nothing about how a slot is built — an empty list beats an invented one.
