How the video slot works

The game is set on a five-reel, three-row grid. There are 243 paylines for you to win and plenty of bonus features too. Before you start spinning, however, you’ll need to choose your bet. Players can select a stake between 0.30 and 30 coins.

As you play the game, you’ll notice a heavy Norse mythology theme throughout, as with the original game. Symbols in Thunderstruck II online slot include the standard A-9 card royals found in a lot of slot games. There are also Viking longships, Asgard and the Bifröst and various characters from Norse mythology. Characters include Valkyries, Loki, Odin and Thor.

As well as the standard symbols, Thunderstruck II includes some bonus symbols to make things more interesting. First off, there are wilds. These are represented by the logo of the game and will substitute for all paying symbols. Every time the wild helps you land a win, it will also double your winnings! Wilds can also payout and are the best paying symbol in the game. Landing five wilds on a line will earn you a big win or 1000x your stake.

The other Thunderstruck bonus symbol is the scatter. These are represented by Thor’s hammer Mjölnir. Landing three or more scatters on a spin will unlock the Thunderstruck II free spins. The free spins round is known as the Great Hall of Spin,s and each time you unlock it, you can progress to another level which includes further bonus features.

The first four times you enter the Great Hall, you’ll get ten free spins, and all wins will be multiplied by five. From the fifth time you trigger the free spins, you’ll unlock fifteen spins and symbols can be randomly transformed into wilds. The tenth time you enter the Hall, you’ll be awarded twenty free spins and symbols can randomly turn into multiplier bonuses. Finally, the fifteenth time you enter the Hall will give you twenty-five free spins which feature rolling reels. Here each win you land will cause the reels to shift, and consecutive wins will increase your multiplier.
