Free spins are slot rounds played without a stake being taken from the player’s balance. The term covers two different things.
In-game free spins are a bonus feature, usually triggered by landing three or more scatter symbols. The number of scatters often decides how many spins are awarded, and many games let players retrigger the feature for extra spins, sometimes adding multipliers or sticky wilds along the way. The exact rules are listed in each slot’s paytable. Promotional free spins are a casino bonus: the operator credits a set number of spins on selected games as part of a welcome offer, a deposit reward, a loyalty gift or a tournament prize. Winnings from them often carry wagering requirements.
Two integrations behind one bonus
Promotional spins need the game provider’s free-rounds support and a bonus engine that tracks awards, expiry and wagering. See our bonus and loyalty tools.
