Slots with free spins
Free spins are the most common bonus in slots: three or more scatters open a round that usually layers on multipliers, sticky wilds or an expanded grid. This is where most of the advertised RTP hides — the base game on its own almost always pays worse than the headline figure suggests. Trigger frequency in modern releases ranges from once every 90 spins to once every 400, and the rarer the bonus, the heavier it tends to be.
How this slice was built
253 games out of the 996 in the catalog. The industry has no shared vocabulary for mechanics: studios describe the same thing in different words, so this list is assembled from a normalised set of spellings found in provider specifications — free spins, free games, free spins choice, sure win free spins, upgrading free spins, hunter spins. If a game uses the mechanic but the provider never listed it, it will not show up here.
