Cats is one of IGT’s longest-running slots, originally released in 2006, and it remains in circulation as a genuine relic of early video slot design. The concept is simple — stacked cat wilds across five reels, multiple cat breeds as distinct payout symbols — but the execution has proven durable enough to outlast most of its contemporaries.

The game plays on 30 paylines with bets from $0.40 to $200 per spin. The adventure theme uses cats as both the central wild symbol and the main paytable characters: different breeds occupy different value tiers, and the stacked cat wild covers multiple positions when it lands. The visual style reflects its era — less stylised than modern releases, more photographic in character.

Stacked cat wilds appear on all reels and substitute for all other symbols. Multiple cat breeds function as distinct pay symbols with individual line values, meaning the paytable is broader than single-symbol wild-based games. Free Spins are triggered by the scatter and continue the stacked wild mechanic with the full breed lineup in play. On a 30-payline structure, stacked cat wilds covering central reels activate a significant portion of the active line count when they appear together.

Cats carries a 95.05% RTP — one of the lower figures in IGT’s catalogue, reflecting the older design era when RTP standards were less competitive. It is medium volatility. The maximum win caps at 500x your stake.

Cats is primarily a nostalgia play — or a curiosity for players interested in the history of video slots. As a mechanical exercise it remains functional, but the 95.05% RTP is a meaningful disadvantage compared to modern alternatives. Worth a session for the history; not the optimal long-term choice on pure mathematics.
