Iron Bank 2 Free Demo: 4,096 Ways, Three Bonus Modes, and the 50,000x Vault

Iron Bank 2 is Relax Gaming’s December 2025 return to the vault: a 6x4 heist grid paying 4,096 ways, selectable base game modes, three different free spins bonuses each with Standard, Super and Ultra tiers, and a 50,000x cap the studio prints itself. The grid, the cap, the launch date and the feature names all come from Relax’s own newsroom and game page; the RTP does not, and for a title this new the sourcing gap is worth spelling out before any real money goes in. The demo below is the free way to learn a game that is really four or five games wearing one bank robber mask.

How the game works

The frame comes straight from Relax’s launch release: 6 reels, 4 rows, 4,096 ways, launched 10 December 2025 as the fifth title built with the CasinoGrounds streaming community. The studio’s own game page adds the bet range, €0.10 to €100 a spin. One database lists a much lower max bet, so treat the provider’s figure as the reference and expect operators to vary.

The sequel’s pitch is choice. From the first spin you pick a base game mode, per the release: Random Mystery, where up to 13 Mystery Symbols can land on a spin, or Random Wilds, where as many as four Wild Multiplier Reels can appear at once. On top sit two paid toggles Relax calls Upgrade Spins: Enhanced Spins at 1.5x stake for a better bonus chance, and Bonus Reels at 10x stake, a new mode the studio says spins for bonus entries. If you played the original, the DNA is recognisable: the 2020 Iron Bank ran on Sticky Mystery Symbols, Expanding Re-Spin Wilds and Progressive Multiplier Wilds, per its own launch release, and the sequel reshuffles those same parts into menus.

Three vaults: the free spins modes

Relax names three bonus types - Multiplier Collect, Mystery Reveal and Expanding Wilds - each in Standard, Super and Ultra versions, which multiplies out to nine variants of the bonus round. A small honesty note: the studio’s own two pages disagree slightly on one name, with the launch release saying Mystery Symbols where the game page says Mystery Reveal, so expect either label in the game client.

The per-mode details below come from reviews rather than Relax, so hold them loosely: Multiplier Collect is reported as 7 spins where collected multipliers attach to wilds, Mystery Reveal as 6 spins with a chosen symbol landing as a mystery on reels 2 to 5, and Expanding Wilds as 6 spins where full-height wilds trigger respins with climbing multipliers. The release also names a Bonus Symbol Boost that can randomly add triggering symbols and a Lucky Boost that can fire as a round begins. Direct entry is priced at 100x, 300x or 900x stake for the Standard, Super and Ultra buys, per Relax’s own release - and a 900x buy on an extreme-variance game is a decision to make with the demo’s lessons, not against them.

RTP honesty check

Here is the part we always verify before repeating: Relax publishes no RTP for this game anywhere we could find on its own domain - not on the game page, not in the launch release. The 96.10% base figure comes from review databases, including co-developer CasinoGrounds, which also lists 96.5% during bonus buys; that second number appears in a single source, so we would not lean on it. Two agreeing secondaries are enough to print 96.10% as reported, not enough to call it confirmed.

What Relax’s page does print is quietly more useful: an Alternative GameID of ironbank2_94 and a German GameID of ironbank2_86. The studio attaches no RTP labels to those IDs, but the natural reading is a 94% build and an 86% build sitting alongside the headline version - and the casino, not you, chooses which one runs. That is exactly the reduced-builds trap our RTP guide walks through: a couple of points of RTP compounds far harder than it looks, and the only figure that counts is the one in the info panel of the casino you actually play at. Check it before the first real spin.

The bottom line

Iron Bank 2 takes the community-built original and turns its engine into a control panel: pick your base mode, pay for your odds, choose your bonus flavour. The 50,000x ceiling and the 4,096-ways grid are studio-printed numbers, the volatility is high by Relax’s own description and extreme by its partner’s, and the RTP story is thinner than we would like for real-money decisions - reported at 96.10%, unpublished by the studio, with game IDs hinting at lower builds in circulation. Learn the modes in the demo first. If the heist-with-a-buy-menu formula is your lane, Money Train 3 is Relax’s harder-edged take on the same idea, and our Relax Gaming hub lists every title of theirs we have covered.
