<p>Mystery Stones puts its Avalanche Multiplier front and center, boosting consecutive cascade wins up to x5 in the base game and up to x15 during Free Spins, while 3 Scatters on the first three reels trigger 10 Free Spins with the chance to add 10 more. Set on a 5-reel, 20-payline layout, the slot leans into chained wins as symbols fall away and fresh ones drop in, giving the multiplier mechanic plenty of room to build momentum. Its mix of retriggerable Free Spins and escalating avalanche payouts gives the Aztec theme a stronger gameplay hook than usual, with a max win of x1,500.</p>
