Odin, Thor, Freya, and Heimdall, the four Norse deity premium symbols, pay between 40 and 200 times your bet for 16 matching symbols anywhere in view. The Thor's hammer Wild substitutes for all standard pay symbols to help form winning combinations, and it can appear anywhere. To activate the Hold the Jackpot Bonus Game, at least six bonus symbols must be shown at once. However, getting between three and five bonus symbols on the same spin makes them all sticky for one spin, which can help you land the additional bonus symbols required to activate the feature.
The triggering bonus symbols become sticky on an otherwise cleared 16-slot grid, and you receive three initial respin attempts. Any new non-blank symbol that lands resets the number of respins to 3, and the feature continues until the grid is filled with sticky bonus symbols or until you run out of respins. Here is a summary of bonus symbols:
If you manage to fill the entire grid with bonus symbols of any kind, you will win the 1,000x Grand Jackpot. The big jackpot is awarded in addition to the amount of your sticky bonus symbols, with a maximum prize of 2,145 times your wager.
