Free Spins

Free spins are bonus rounds where you spin without paying. They're triggered by landing enough scatter symbols during the base game, typically 3 or more. The number of free spins you receive varies by slot, usually somewhere between 8 and 25, and many games let you retrigger by landing more scatters during the bonus.

Free spins usually come with enhanced features that don't exist in the base game. Increasing multipliers, extra wilds, expanded reels, or special symbols that collect values. This is where the slot's real payout potential lives. For most high-variance slots, over 60% of the total RTP comes from the bonus round.

One thing that gets overlooked: free spins as a bonus round in a slot game and free spins as a casino promotion are different things. When a casino offers you "50 free spins on Starburst," those are promotional free spins with wagering requirements attached. The free spins inside a slot's bonus round have no wagering attached because you're already paying for them through the base game's math.
