How to Play Thunderstruck II
Thunderstruck II uses a 5x3 grid with 243 ways to win. There are no traditional paylines. You win by landing 3 or more matching symbols on adjacent reels from left to right. Here is how the game works:
Set Your Bet
Choose your stake between R0.30 and R150 per spin. The game uses 243 ways to win. Any 3 or more matching symbols on adjacent reels from left to right pays out.
Spin the Reels
The 5x3 grid fills with Norse mythology symbols. Land 3 or more matching symbols on adjacent reels from left to right to win. The Thor hammer wild substitutes for all symbols except the scatter.
Watch for Wildstorm
At any point during the base game, the Wildstorm feature can activate randomly. Between 1 and 5 reels transform into wild reels simultaneously, creating the potential for massive wins.
Enter the Great Hall of Spins
Land 3 or more scatter symbols to trigger the Great Hall of Spins. The chamber that activates depends on how many times you have previously triggered the bonus. Valkyrie, Loki, Odin and Thor chambers unlock progressively.
