Mystery Nudge Gates
Mystery Gates are 4-height symbols that can land partially outside the reels and then nudge up or down until they cover the full reel. Mystery Gates can land anywhere on the grid. When this happens, the global multiplier increases by +1. Gates move up or down(1 tile at a time) in order to cover their entire reel in the fastest way possible. Every time a Mystery Gate nudges up or down, the global multiplier increases by +1. After a Gate covers its entire reel, it opens to reveal any type of paying symbol, Wild symbols or Eye symbols. Each symbol reveals coins and special symbols. Multiple Gates at the same time always reveal the same type of symbol.
Coin Feature
When the Eye symbol is revealed by the Mystery Gates, they open and can reveal Coins, +FS or Collector symbols. Additional FS symbols can only be revealed during the bonus games and grant their value as Additional free spins. They can come with values +1, +2, or +3. All Cash Prizes are paid as a multiple of your bet and are added to your win for the spin. They come in 3 tiers;
- Bronze Coins can have the following values: 1x, 2x, 5x.
- Silver Coins can have the following values: 10x, 15x, 20x, 25x, 50x.
- Gold Coins can have the following values: 100x, 250x, 500x, 1000x.
The Collector symbol collects all cash prizes and the values of other Collector symbols on the screen before respinning only the Cash Prize positions. Collected Collector symbols keep their initial value.
Global Multiplier
The Global Multiplier starts at 1x. Every time a Mystery Gate lands, the Global Multiplier increases by +1. When a Gate nudges up or down, the Global Multiplier also increases by +1. During the bonus games, it is persistent for the entire duration of the bonus round. At the end of the spin, the values of all coins and Collector symbols will be added together and multiplied with your bet amount to determine the final cash prize, which will be added to the Total Win.
Odin’s Trial
Trigger the Odin’s Trial bonus with 10 free spins by landing 3 Bonus Scatter symbols at the same time in the base game. Base game mechanics are followed with an increased chance to land Mystery Gates. In addition, the Mystery Gates become sticky and reveal paying symbols, wild symbols or Eye symbols on each spin. The global Multiplier is persistent for the entire duration of the bonus round. An additional 1-3 free spins can be awarded by revealing the +FS symbols from the coin feature.
Fury of the Gods
Trigger the fury of the Gods with 10 free spins by landing 4 Bonus scatter symbols at the same time in the base game. Base game mechanics are followed with an increased chance to land Mystery Gates. In addition, the Mystery Gates become sticky and reveal high-paying symbols, Wild symbols or Eye symbols on each spin. The global Multiplier is persistent for the entire duration of the bonus round.
Bonus Buy
The Bonus Buy section allows players to activate BonusHunt FeatureSpins for 2x the bet to make each spin three times more likely to trigger a bonus or Runic FeatureSpins at 50x, which guarantee at least two Mystery Nudge Gates on each spin. Odin’s Trial may be bought for 100x or Fury of the Gods for 200x.
