The first thing that stands out in Siberian Storm is the slightly unusual set up. There are the standard 5 reels, but they're configured in a hexagonal shape with 3 columns on the outer two reels, four on the next two and five in the middle. That all adds up to a 720 ways to win payout structure which means wins from right to left as well as left to right.
The Siberian Storm reels feature a pair of tigers as well as a selection of jewel encrusted relics. The Siberian Storm logo is the biggest payer offering 1,000 coin payouts for 5 symbol combinations. There's also a wild which appears on reels 2, 3 and 4. The scatter offers payouts of between 2 and 50 times your total bet depending on the number of scatters you hit. Many of the symbols on the middle reels are stacked which further boosts your chances of finding a winner.
The chief draw in Siberian Storm is the Free Spins feature which is triggered by hitting the Tiger's Eye Bonus symbol on 5 consecutive reels - that will get you an initial 8 free spins. A further 8 free games are awarded for every 5 symbol combination on the triggering spin so in theory you could start with 96 free spins.
You can also trigger further re-spins in chunks of 8 if you hit the Tiger's Eye Symbol during the bonus feature - a maximum of 240 free spins are possible!
The volatile nature of Siberian Storm made it a big hit with slot players in land-based casinos in Las Vegas - that high variance is much in evidence in the online version too. Expect plenty of dry spells but watch out when the wins arrive as they can be spectacular.
The visuals may look a little tired to players accustomed to glossy high-definition graphics but the gameplay has stood the test of time. Get lucky in the feature and there are chances to walk away with some impressive hauls of coins. I would also recommend Prowling Panther which is similar and also by IGT (and very good too!).
