The 2025 Iron Bank 2 keeps the grid, ways, 0.1-to-20 bet range and high-volatility profile, while nudging the maximum to 50,000x and RTP from 96.2% to 96.1%. The meaningful change is inside the feature cycle: Energy collection, walking and sticky wilds, guaranteed wilds during free spins, extra spins and reelset changes make the sequel a more persistent wild-driven version of the same heist formula.
