Cat Stacks

About this Slot

Cat Stacks is a medieval pets-themed slot from OneSpin with an RTP of 95.99%, medium volatility and a maximum win of 12,500x. The game uses a 6x5 board where wins land with 8 or more matching symbols anywhere on the board, rather than on fixed paylines. Wild symbols substitute for pay symbols and stay held when they form part of a winning combination, allowing chain reactions as non-winning symbols refill. Scatter symbols also stay held when they land, and 4, 5 or 6 Scatters trigger the Bonus, Super Bonus or Epic Bonus respectively. The Retrigger symbol behaves differently depending on game mode: in the base game or Ante mode, reaching the top transforms it into a Scatter to help trigger a bonus; in bonus rounds and Full Screen mode, it becomes +1 and awards one extra spin. When a column fills with Claw symbols, it doubles the held pay-symbol count contribution in that column. Food Bag symbols add a one-time multiplier between x2 and x500 to the global multiplier when their column fills. Gold Coin symbols add a permanent multiplier between x2 and x100 to the global multiplier during bonus rounds when their column fills. The Bonus mode starts with 4 Scatters, awarding 10 free spins and guaranteeing at least 1 top-row special. Super Bonus triggers on 5 Scatters with 10 free spins and at least 2 top-row specials. Epic Bonus requires 6 Scatters and grants 10 free spins with at least 3 top-row specials. Full Screen costs 50x bet and fills the top row with special symbols, awarding up to 3 respins from top-row Retriggers. Ante costs 3x bet and significantly increases the chance of triggering a Bonus Mode. The Bonus buy option costs 100x bet, Super Bonus costs 200x bet and Epic Bonus costs 500x bet.
