About this Slot
Key Master is an action and adventure slot by Penguin King with an RTP of 95.7%, high volatility and a maximum win of 20,000x. The game plays across five reels, four rows and 21 paylines.
The chest and key system forms the core mechanic. Coloured chests land on reels two through five only, appearing in groups of up to ten per spin. When a key matches the colour of a chest, that chest transforms into a wild with a multiplier attached.
Three Scatter Padlock symbols trigger Free Spins, awarding ten spins. Landing two Scatter symbols during the feature adds three extra spins. During Free Spins, all chests and wilds lock in place, remaining on the reels for subsequent spins.
The Golden Key appears during Free Spins and transforms all remaining chests for the duration of the feature. Once the Golden Key lands, no other keys can appear on the reels.
A Bonus Buy option is available, allowing players to purchase direct entry into the Free Spins round.
