Basic Information

Released in December 2025, Iron Bank 2 is the long-awaited sequel to Relax Gaming’s popular slot Iron Bank. Both games play on a 6x4 grid with 4,096 ways to win, and feature a choice of 3 potential bonus games. 

However, the sequel builds on the original by adding new elements. The Dual Base feature lets you adjust the base game mechanics, while the free spins rounds now have 3 levels each. There’s a lot more to discuss, so let’s begin with the graphics.

Theme and Graphics

Iron Bank 2 follows the story of a bank robbery in the Cuban capital of Havana. The base game is set on the city streets, while the bonus games immerse you into the heist itself. 

Visually, the graphics do a great job of showing this title’s many features, making it easy to focus on the gameplay and outcomes. On top of that, the cartoony symbols and smooth animations create a playful atmosphere that contrasts the volatile gameplay. 

RTP and Volatility

As a provider, Relax Gaming have a reputation for releasing high variance slot games, and Iron Bank 2 is no different. Described as extremely or explosively volatile, you won’t be earning wins every round, but your payouts should be quite large when you do. 

This volatility is paired with a fairly standard Return to Player (RTP) rate of 96.1%. For context, an RTP like this means that, across millions of game rounds, players generally earn just over €96 for every €100 wagered. 

Symbols and Paytable

Iron Bank 2 features 10 regular symbols that pay more the rarer they become:

Low-Paying Symbols are the most common, consisting of the 10-A card values. A winning round with 6 of these pays 0.4x-0.8x, depending on the symbol.

Next are the Medium-Paying Symbols featuring blueprints, grappling hooks and whiskey. With 6 of these, you will earn 2x-4x your bet. 

Finally, the High-Paying Symbols are the Pineapple and the Bull, which pay either 10x or 50x when you find 6 of them. 

How to play the slot

Iron Bank 2 is an easy game to play. Simply wager an amount within the €0.10-€20 betting range and hit the ‘Spin’ or ‘Autoplay’ buttons to begin. From there, you earn payouts whenever 3 or more matching symbols land on adjacent reels, with a total of 4,096 ways to win. 

Game Mechanics

This game offers you a unique opportunity to change the base gameplay to your liking. The Dual Base Feature has 2 distinct modes for you to choose:

• Random Mystery Mode: Up to 13 Mystery Symbols can land on the reels. These all reveal the same symbol, increasing your odds of earning high-value payouts.

• Random Wilds Mode: Up to 4 Expanding Wilds can land on the reels. They fill the whole reel and carry 2x-10x multipliers.

Feature Symbols Explained

This game has 2 special symbols that behave differently to the regular ones:

• Wild Symbols: Wilds can stand in for any regular symbol. On their own, 6 Wilds pay 50x your bet. Meanwhile, in the Free Spins and Random Wilds game modes they can expand to fill the whole reel. 

• Bonus Symbols: Landing 3 Bonus Symbols triggers a choice of 3 Free Spins Rounds. With 4+ symbols, the bonus games are upgraded to Super or Ultra Free Spins and offer better rewards.

Iron Bank 2 Slot Features and Bonuses

Iron Bank 2 has a lot of bonus features for you to unlock, so let’s go through them. 

Upgraded Spins

Before any bonuses are triggered, you can increase your odds of entering bonus rounds with these Upgraded Spins mechanics:

• Enhanced Spins: Bonus Symbols are more likely to land on the reels. This costs 1.5x your bet. 

• Bonus Reels: Pay 10x your bet for all regular symbols to be removed, with exclusively Bonus Symbols appearing on the reels.

Mystery Symbol Free Spins

With 3 Bonus Symbols, you can choose the Standard Mystery Symbols round with 6 free spins.

A symbol is selected before the round, which converts to Sticky Mystery Symbols on the reels. After each spin, these Mystery Symbols reveal matching icons to help you achieve wins. The more of them you find, the more free spins you unlock. 

4 or 5 Bonus Symbols upgrade this round to Super or Ultra Free Spins. The gameplay is identical, but each new level makes winning easier by adding another row to the reels, taking the layout from 6x4 to 6x6. 

Expanding Wilds Free Spins

Choosing the Standard Expanding Wilds round gives you 6 free spins. Wilds that land in the center reels expand and trigger a re-spin. Every win using these Wilds ticks up a multiplier, and when both win, the multipliers are applied to each other first, and then to your payout. 

In the Super and Ultra Free Spins mode, the Wilds get pulled in from other reels, increasing your chances to win. Here, the Wild Multipliers also start at 3x or 6x respectively. 

Multiplier Collect Free Spins

You start with 7 free spins in the Standard Multiplier Collect round, where Coconut Shooters sit atop the reels.

When 3 coconuts are collected from special Coconut Crates, the Free Spins Counter and Reel Multiplier increase by 1. When a Wild symbol forms a win, the Reel Multiplier above it is applied to your payout. 

During Super and Ultra Free Spins, 1 or 2 Expanded Wilds remain sticky for every spin.

Demo Features and Mobile Compatibility

When playing this game from an iOS or Android mobile phone, the first thing you’ll notice is that the button layout is slightly different to accommodate for the portrait orientation. However, that will probably be the only thing you notice.

Iron Bank 2 runs just as smoothly on smaller devices as it does on desktops. This gives mobile gamblers the freedom to enjoy the title from anywhere there’s an internet connection. 

Iron Bank 2 Compared

Iron Bank 2 is an excellent addition to Relax Gaming’s library of high volatility games with playful themes. 

It’s more complex than many of the provider’s other titles, which gives adventurous casino players a good challenge to test their skills, and rewards them with large payouts when they get lucky. 

Similar Slots You Might Like

If you enjoy this game and would like to play some similar titles, allow us to suggest:

• SixSixSix by Hacksaw Gaming: Another high-volatility title with complex bonus mechanics. Take advantage of the Wicked Wheels to make Deals with the Devil and earn a haunting max prize of 16,666x your bet. 

• Kong by Trifecta Gaming: A thrilling slot themed around an ape’s rampage through New York. Featuring a multi-levelled bonus round and Expanding Reel mechanics, stack multipliers together to earn up to 100,000x your bet. 

• Mental 2 by Nolimit City: Following Nolimit City’s Mental, this slot has darker themes, but matches Iron Bank 2’s extreme variance. With a 99,999x max win, this game’s terrifying visuals are not for the faint-hearted. 

Summary & Final Verdict

Overall, Iron Bank 2 is a fast-paced and exciting slot. The smooth animations and clear graphics make it easy to track wins, while the Dual Base Feature makes the base game very versatile. 

However, the many features and bonus rounds can feel excessive, and we think the slot could appeal to more gamblers with fewer mechanics at play.

That being said, if high-volatility titles are your thing, this one is great at keeping you invested and entertained even when you aren’t winning. If you don’t like elaborate casino games though, you may want to explore other titles.
