What is a free spins bonus round?
A free spins bonus round is a feature triggered inside a slot game that awards a set number of spins at no cost to your balance. Any winnings during free spins are added to your real balance, making them one of the most valuable features a slot can offer.
How it’s triggered
Free spins are typically triggered by landing a specific number of scatter symbols, usually 3 or more, anywhere on the reels. The number of free spins awarded often depends on how many scatters land — 3 scatters might give 10 free spins while 5 scatters give 25 or more.
Enhanced mechanics during free spins
The base free spins round is rarely the full picture. Many slots add multipliers that increase during the round, sticky wilds that build up with each spin, or extra wilds that substitute for more symbol types. Some games offer multiple bonus round variants with increasing multipliers or additional features, selected by the scatter count or via a gamble mechanic.
