What is Ante Bet (Slots)?

An ante bet in slots, sometimes labelled bet boost or double chance, is an optional setting that raises the cost of each spin, typically by twenty-five or fifty percent, in exchange for a higher chance of triggering the free-spins round. The game usually delivers this by adding extra scatter symbols to the reel set or by removing a low symbol. Ante bet is distinct from a bonus buy, which pays a fixed price for an immediate feature; the ante only improves the odds of a trigger, and a session can still end without one. Providers normally publish separate RTP figures for ante on and ante off, and the two are often close, so the setting mainly changes volatility and the speed at which a balance is consumed rather than long-run return.
