The symbols of the game:

  • The game logo is the Wild
  • The bonus logo is the Scatter
  • Thor
  • Odin
  • Loki
  • Viking Ship
  • Playing Cards


It is loaded with features. Therefore, the gameplay seems to be an exciting one. Firstly let’s talk about the Wild symbol, which substitutes for all symbols except for scatters. Moreover, the prize will double when Wild appears in a winning combination.

Wild Storm Bonus Game

You have great opportunities in the bonus game. It can be randomly activated during any regular spins. Up to 5 reels transformed into wild reels. Wild and scatter don’t appear while this feature is active.

Great Hall of Spins

Each game awards free spins and an additional bonus. After five sequential activations, one of the bonus games is unlocked.


All wins during this game will be multiplied by 5x. Valkyrie can be reactivated.


Players get the same number of extra free spins whenever 2-5 scatters appear in a free spin. On top of all, when the Wild Magic symbol turns up on reel 3, it will transform up to 15 symbols to Wild.


Any win activates the Wild Raven feature. So what does this mean for your play?

When Odin is in play, random symbols are transformed into wilds and multiply wins up to 6x. Unfortunately, however, this play can’t retrigger.

Winning combinations will be removed, and symbols falling from above fill the space. Repeats itself till you continue to win, and the multiplier increases with each win up to 5. This setup increases the chance for some big win without betting on a new pin. Unfortunately, no reactivation is possible for Thor.
