Mystery Stones

Mystery Stones is built around falling symbols and an Avalanche Multiplier. A win removes its symbols, allowing new ones to drop into the grid and possibly form another combination in the same spin. Each successive win increases the multiplier, up to x5 in regular play. Scatters on the first three reels start ten Free Spins, where the multiplier can reach x15. The ancient-stone setting gives those cascades a sense of excavation, while the reel changes remain straightforward to follow. A longer sequence of connected wins can be more valuable than a single initial line.
