Fort Knox series
Fort Knox series and IGT's crossover niche
IGT uses the Fort Knox series as a crossover lane, recasting familiar Cats, Cleopatra, Da Vinci Diamonds and Wolf Run identities inside bonus-led games rather than extending one continuous story. The recognizable themes provide the entry point, while each reel setup and feature package determines how that version plays.

The first pairing shows the range inside the label. Fort Knox Cats uses a 5x4 screen with 30 paylines, while Fort Knox Cleopatra uses a tighter 5x3 layout with 20 lines and can award additional free spins. Both arrived in 2024 with listed 10,000x ceilings, so the main distinction is screen density and bonus behavior rather than headline reward potential.
Fort Knox Da Vinci Diamonds pushes the formula further in 2026 through cascading wins, a pick-object bonus and fixed jackpots on a 5x3, 20-line screen. Fort Knox Wolf Run instead centers a five-reel bonus game with wilds, free spins and multipliers. Fort Knox therefore works less as a sequel chain than as IGT's remix label, with established themes attached to materially different bonus architectures.
