About this Slot
Pengos Mystery is a Christmas-themed game from Hammer Head Gaming with a 5x5 grid and cluster pays. The RTP is 96% with high volatility and a maximum win of 50,000x.
Mystery symbols freeze when three or more touch each other, triggering a re-spin. When new mystery symbols land adjacent to the frozen group during a re-spin, they expand the frozen area. When re-spins end, the entire frozen cluster converts to a single symbol, wild symbols, or coins.
Three scatter symbols trigger Cold Snap, awarding 10 free spins. During Cold Snap, mystery symbols appear more frequently. Four scatter symbols trigger Deep Freeze, also awarding 10 free spins. In Deep Freeze, frozen mystery blocks become wild symbols or coins, and the bonus includes collector bags and multipliers. Five scatter symbols trigger Whiteout, again awarding 10 free spins. During Whiteout, frozen mystery blocks become coins only, and those coins are silver or higher in value. Whiteout also features collector bags and multipliers.
Extra Chance increases the frequency at which bonus features are triggered during base gameplay. The Feature Buy option grants direct access to the bonus rounds, with three separate entry point options available.
