The first thing you notice is the grid. Five reels packed into a hexagonal shape, the outer columns narrow, the centre deep, framed in ice with turquoise light bleeding through from behind. It looks different because it is different. IGT’s 3-4-5-4-3 layout is what makes 720 ways to win possible on a five-reel slot, and the whole structure of the free play experience flows from that single design decision.
Siberian Storm runs on IGT’s MultiWay Xtra format, which means wins pay left-to-right and right-to-left simultaneously. A matching symbol anywhere in a column counts, and if more than one of the same symbol lands in the same column, the win multiplies accordingly. The wild appears on reels 2, 3, and 4 only, and substitutes for all symbols except the scatter. Only the highest MultiWay Xtra win for each symbol type is paid per spin, but wins from different symbols stack.
The Tiger Eye scatter triggers the Free Spins Bonus when it lands anywhere on five consecutive reels. Each trigger awards 8 free spins, but if multiple combinations qualify on the same spin, the totals combine. Up to 96 spins can be awarded from a single trigger. The bonus reels are a separate set from those used in standard play, which affects symbol distribution and win frequency during the feature.
Retriggering works the same way: five consecutive Tiger Eye scatters during the bonus add another 8 spins, and the feature can retrigger multiple times up to a cap of 240 free spins per bonus session. Spins run at the same coin value as the triggering spin. One structural note: if the transaction cap of 300,000 coins is reached mid-bonus, the feature ends immediately, even if spins remain.
The game’s 720 ways to win are always active across its hexagonal grid.
Siberian Storm uses a fixed bet of 50 coins per spin. You can modify the coin value to adjust your total stake, with the minimum coin value resulting in a total bet of €0.50 per spin.
All MultiWay Xtra wins are multiplied by the coin value. The tables below show win values in coins for 5, 4, and 3 matching symbols. The base game and Free Spins Bonus use separate reel sets, so the values differ between them.
