Iron Bank by Relax Gaming pulls you into a 1950s Havana heist. 4,096 ways, 49,998x max, three free spins flavours to pick.
Relax Gaming dropped Iron Bank in November 2020 as the opening act of what became their Iron Bank series. The setup is a slow-burn Havana heist circa 1955, complete with a leopard kingpin in a sharp suit, a bull enforcer who looks ready to snap a kneecap, and a supporting cast of animal mobsters who'd feel at home in a Tarantino reel.
Mechanically, you're working a 6×4 grid with 4,096 ways and a 96.20% base RTP. High volatility, 25% hit rate. Bets run from 0.10 to 100 EUR, which is a wide enough spread for casual players and the occasional whale. Max win sits at 49,998x. Not a typo, just Relax being weirdly specific.
Base game has three random modifiers that fire whenever they feel like it. Random Mystery Symbols drop 2 to 8 mystery tiles that all reveal the same symbol. Random Bonus Symbols seed extra scatters to nudge you toward the bonus. And the one you actually want, Full Reel Wilds, paints an entire reel with leopard wilds carrying a flat x10 multiplier. Land that on a busy spin and the math gets silly fast.
The free spins menu is where Iron Bank earned its reputation. Trigger the bonus and you choose your flavour:
Sticky Mystery gives you 8 spins where mystery symbols lock in place until the round ends. Slow start, brutal finish. Expanding Wilds hands you 10 spins, and every wild triggers a re-spin while expanding to fill its reel. Multiplier Collect is the popular pick. 12 spins, and every wild multiplier you land gets banked, then applied to wins for the rest of the round. Stack a few x10s and you're suddenly looking at numbers that don't fit on the screen.
There's also a Buy Bonus at 100x with RTP nudged up to 97%. UK players don't get this option, courtesy of the UKGC ban on bonus buys. Fair enough, honestly, those things are a budget killer.
Is Iron Bank perfect? Not quite. The base game can run cold for stretches, which is the price you pay for high volatility. But when it hits, it really hits. Five years on and it still holds up better than most slots released last quarter.
