Iron Bank 2: Relax Gaming and CasinoGrounds Reunite for Cuban Slot Sequel

Five years after their first collaboration on Iron Bank, software developer Relax Gaming and streaming hub CasinoGrounds reunited for another venture, Iron Bank 2. The sequel retains the core mechanics of the original slot while refining its bonus structure with standard, super, and ultra variants of its three bonus rounds. Players have more control over gameplay with the adjustable strategies.

Set against a sun-kissed Cuban backdrop, the game reuses the tropical aesthetic with vibrant visuals, palm trees, vintage cards, and the Iron Bank sitting to the grid’s left. The bank is a treasure trove that comes alive during bonus rounds.

Dynamic Paytable and Volatile Wins

Iron Bank 2 features a 6x4 grid with 4,096 ways to win, with bets ranging from $0.10 to $20 per round. The game’s high volatility pairs with a 96.1% RTP, aligning with modern slot trends.

Symbols span from the poker cards 10–A, paying low-value wins of up to 0.8x the bet, to thematic icons like cigars, bejeweled necklaces, and bulls, with a combo of six awarding up to 50x. Wilds land on any reel, substituting standard symbols and yielding a 50x payout when six land from the leftmost reel.

Bonus Mechanics

Iron Bank 2 adds a touch of strategy to gameplay with layered customization, starting with two base game options: the Random Mystery feature that adds up to 13 mystery symbols or Random Wilds that deploy 2-10x multipliers across the second through fifth reels. These multipliers compound when overlapping in wins.

Free spins activate through 3+ scatters, with players selecting from three modes: Multiplier Collect, Mystery Symbol, or Expanding Wilds. Landing 4-6 scatters upgrades spins to “Super” or “Ultra” tiers, while the Lucky Boost randomly amplifies the winning potential.

The standout Multiplier Collect mode awards seven spins, where coconuts award multipliers to specific reels. Collecting three coconuts per reel grants three extra spins and increases wild multipliers, with Super/Ultra tiers introducing walking or expanding wilds.

More Bonus Customization

The Mystery Symbol bonus awards six free spins, with sticky symbols on reels 2–6 revealing identical icons. Super/Ultra tiers expand grid rows, while collective 6+ symbols grant two more spins. Meanwhile, expanding wilds award respins on reels 3–4, with persistent multipliers starting at 1x applying to all wins. During Super Spins, wilds are dragged onto the center reels and add a 3x multiplier, while Ultra tiers lock wilds at 6x.
