Iron Bank 2 - Demo & Slot Review

The game runs on a 6-reel, 4-row grid, offering 4,096 ways to win, no traditional paylines. Bets go from 0.10 to 20 per spin. The stated RTP is 96.10%, and volatility is very high (or extreme), so expect swings: wins might be rare, but when they happen, they can be huge. The maximum win is a massive 50,000x your bet.

In the base game, the slot uses a special “Dual Base Feature” allowing you to choose between two base-modes before each spin: one populates Mystery Symbols, the other sets up Wild reels with multipliers. There are also bonus mechanics, a variety of free-spins modes, random modifiers, and a “Feature Buy / Upgrade Spins” option to jump straight into bonus rounds.

• Dual Base Feature (Random Mystery or Random Wilds): Before each spin you pick one of two base-game modes. The “Mystery” mode can place up to 13 Mystery Symbols, all of which will turn into the same paying symbol after the spin, great for triggering big wins. Alternatively, the “Wilds” mode can turn up to 4 entire reels into Wilds, each carrying a random multiplier.
• Bonus Symbol Boost: Occasionally, 1-3 Bonus Symbols are added onto the reels just before they stop. This increases your chances to trigger the main Free Spins rounds.
• Free Spins: Landing bonus symbols triggers the free spins feature. With 3 Scatters you get the regular bonus, 4 Scatters award the super bonus, 5 Scatters unlock the ultra bonus, and 6 Scatters give you the ultra bonus plus an additional 2,000x win. At the start of every bonus, you can choose one of three bonus paths: Mystery Symbol, Expanding Wilds, or Multiplier Collect.
• Mystery Symbol (Free Spins): In this bonus mode, one symbol is randomly chosen as a fixed Mystery Symbol. You begin the bonus with 6 free spins and a standard 6×4 grid. When your selected Mystery Symbol lands, it locks in place for the entire bonus. On every spin, it reveals a random symbol. A meter in the top-left corner fills as Mystery Symbols appear, awarding additional spins accordingly. The same mechanics apply in the Super version, but the grid gains an extra row (6×5). In the Ultra version, things heat up and the win potential is significantly higher, as the grid expands to a full 6×6.
• Expanding Wilds (Free Spins): This bonus starts with 6 free spins. Reels 3 and 4, which are marked on the grid, are the main focus. If a Wild lands on either of these reels, it expands to cover the entire reel and triggers a respin that continues until no new wins occur. With every win, the Wild reel’s multiplier increases by +1 and does not reset during the bonus. If both reels have active Wild reel, their multipliers are multiplied together before being applied to the win. In the Super version, the Wild reel multipliers start at x3, and any Wilds that land on reels 2 or 5 will shift to reel 3 or 4 if those reels do not already contain Wilds. In the Ultra version, the multipliers begin at x6, and any Wild landing anywhere on the grid moves to reel 3 or 4 and activates the respin mechanic.
• Multiplier Collect (Free Spins): This bonus begins with 7 free spins. Above reels 2-5, you’ll see multiplier boxes. Your goal is to collect coconuts, which appear in wooden crates on the reels. Each crate awards a random number of coconuts to the box above its reel. When a box is filled with 3 coconuts, its multiplier increases by +1 and you gain one extra spin. When a Wild lands on a reel with a multiplier box, it adopts that box’s multiplier. If multiple Wilds are part of a win, their multipliers are multiplied together before calculating the payout. In the Super version, the same core mechanics apply, but every spin is guaranteed to have at least one walking Wild Reel. The Ultra version is also similar, but features two walking Wild Reels that move around the grid throughout the bonus, greatly increasing the potential for big wins.
• Upgrade Spins:
  • Enhanced Spins (1.5x bet): Increased chances of triggering a bonus.
  • Bonus Reels (10x bet): All regular symbols are removed and only Bonus symbols can appear.
• Feature Buy:
  • Normal Free Spins (100x bet)
  • Super Free Spins (300x bet)
  • Ultra Free Spins (900x bet)
