Grimalkin from Air Dice is a dice-based game with a four-box layout, each box arranged in a 3 x 3 grid and featuring five symbols per box. The published return to player is 96.00%, while the betting range runs from 25.00 credits to 200 times the minimum bet. The game has no jackpot feature.
The review materials point to standard gameplay supported by special symbols and bonus rounds, including mystery mode and mini mystery bonus features. With no payline structure in the usual slot sense and a listed 0.25 paytable win line value, the format places emphasis on the game's symbol combinations and bonus mechanics rather than fixed lines.
A demo version is available, allowing players to play for free and practice before playing for real money. The game is presented as a high-volatility release with maximum exposure noted as high, making the free demo useful for learning the structure, symbols, and bonus game flow before staking credits.
