Features Winter Thunder is a five-reel online slot from Belatra with 25 paylines and a fixed RTP of 96.03%. The game uses high volatility, with winter-themed symbols including bears, eagles, lynxes and a winter wolf wild that covers two reel positions. If only part of the wild lands, the reel nudges to reveal the full symbol.
The Snowy Mountain scatter triggers free spins when three or more appear, with each scatter adding more spins. During this round, all winnings are multiplied by a global multiplier equal to the total number of free spins, and retriggers are possible. A Hot Mode feature can also activate with five scatters, while the maximum payout is set at 12,000x the stake.
The slot also includes a Hold-and-Win bonus with three respins, plus bonus and extra bonus symbols that can award Mini, Minor, Major or Grand jackpots. A lightning strike feature may add an extra spin, and a Buy Bonus option is available for players who want to access the free spins, Hold-and-Win or Hot Mode directly in the demo version to practice before playing for real money.
