The game is based on accumulating various matching keys. There are 5 keys in each set and finding all of the keys in a particular set will earn you 10 free spins. With these ten additional spins, players will have the opportunity to win one of five unique progressive jackpot prizes. Every jackpot has its own colour and it is possible to win multiple jackpots within the free spin mode. This five of a kind collectible mechanic is a popular feature in many of Yggradsil’s video slot games.
Landing 3 scatter symbols (in the form of magic mirrors) will take you to one of two bonus features. The jackpot free spins were previously discussed but players may also be able to experience the treasure chest bonus game.
This bonus game mode starts with players choosing one of three different treasure chests from the throne room. One chest will be a lucky one and if it is successfully picked, players will receive a prize. The prize will either be another key for their collection or the opportunity to progress to the next level. This bonus game mode can continue indefinitely until an empty chest is chosen and kicks off an avalanche that takes the player out of the throne room.
In addition to these bonus features, there are also two mirror scatter symbols. These mirror scatters activate a pick and click game. Here, you get the chance to pick from one of five chests possibly containing free spins, bonus games, or more keys!
