Mystery Symbol Feature Game Rules

• The game has two modes for the Mystery Reveal symbols: Lockdown mode and Mixed mode.
• In Lockdown Mode all Mystery Reveal Symbols have the same counter.

Super Free Spins Game Rules

• Super Free Spins are triggered once 2000 keys have been collected from the base game.
• Key collection can be done on both modes of the game.
• During the free spins, mystery symbols don’t count down, but reveal as soon as they land.
• An additional ‘Golden’ mystery symbol is added during the free spins. The ‘Golden’ mystery symbol requires 2 cascades to award one additional spin and transform into a random symbol.

Key Collector Game Rules

• In the main game, key symbols appear randomly on top of normal symbols. Each key symbol awards 1-10 keys. After the keys have been collected, the normal symbol behaves as normal.
• After the keys have been collected the key symbol is transformed to a normal symbol.
• After collecting 2000 keys Super Free Spins are triggered, and the key collect is re-set.
• If more than 2000 keys are collected before triggering Super Free Spins, the additional keys are saved and fill up the collect once it has been reset.
• The bet values for each collected key is saved, and the bet size Super Free Spins are played at is the weighted average bet size during the collection with weights proportional to number of keys collected.
• The average bet size must be an integer multiplier of the minimum bet. If it is not it is rounded according to the rules of Stochastic rounding. E.g. if the average becomes 1.2 times the minimum bet, with a 20% probability it will be rounded to 2 times the minimum bet and with 80% probability it will be rounded to 1 times minimum bet.
