About this Slot
Atom Winter is an animals, nature and sci-fi themed slot by GIG Gaming with an RTP of 96.69%, high volatility and a maximum win of 25,000x. The game plays across 5 reels, 6 rows and ways to win.
Egg Wild expands a reel to a wild symbol and substitutes for all paying symbols. Atom Split adds an extra row to the grid, increasing the total ways to win: at 4 rows the game offers 1,024 ways, at 5 rows 3,125 ways, and at 6 rows 7,776 ways.
Mutation transforms low-value symbols into premium symbols before any payout is calculated, and always creates a winning combination from the spin result. Atom Bomb fills a radiation meter across consecutive spins and triggers once the meter reaches 10 lights. When Atom Bomb activates, all symbols on the reels explode and receive multipliers ranging from 2x to 1,000x, with each winning combination using the highest multiplier available on that reel.
Free Spins are triggered by 3, 4 or 5 Snow Globes and award 10 free spins. Any rows added by Atom Split remain in place throughout the bonus round. Egg Wilds stay sticky during free spins, with a maximum of 2 sticky wilds on the reels. Every winning spin during the bonus fills the radiation meter, but free spins cannot be retriggered.
Bonus buy options are Double Chance at 1.5x per spin, Bomb Spin at 10x per spin, Free Spins at 400x bet, and Super Free Spins at 1,000x bet.
