Iron Bank 2

Iron Bank 2 Review

Iron Bank 2 is a follow-up to the original Iron Bank game that came out back in 2020, created by Relax Gaming in conjunction with the streaming community CasinoGrounds. This Cuban-themed release turned out to be quite successful, and even now, 5 years later, it remains popular among online gamblers. Sooner or later, a sequel was, and now we finally have it – way bigger and presumably better.

The Iron Bank 2 online slot keeps a lot of elements of its older sibling intact – it utilizes a 6x4 reel setup with 4,096 ways to win on each spin, and the gameplay is packed to the brim with bonus features, with the main attraction being the three types of free spins. And yet, the number of bonus features has been increased dramatically, providing players with way more variety than ever. They've expanded the mechanics, and now each of the free spins options comes in three tiers, and things got a little busier in the base game too.

Iron Bank 2 Slot – Base Game

The game is built on the high-volatility formula, offering plenty of potential for extreme winning outcomes. Bets range from 0.10 to 100 EUR per spin, making it suitable for both casual and high-stake sessions. The theoretical RTP stands at 96.1%, and the maximum win reaches an enormous 50,000x the bet – on par with the original title.

Bonuses And Special Features

Relax Gaming has expanded the feature package considerably in Iron Bank 2, building on the foundation of the first game with a much larger set of mechanics. Below, we’ll walk through each feature in detail.

Dual Base Feature

Iron Bank 2 lets you switch between two base game modes, namely Random Mystery and Random Wilds. Each mode applies its own type of modifier on any spin and can change the way wins form.

Random Mystery mode can add up to 13 Mystery symbols before the reels stop at random. These symbols land as overlays and all reveal the same symbol once the spin settles.

Random Wilds mode enables random full-stacked Wilds on reels 2–5. Each Wild carries a multiplier between x2 and x10, and multipliers combine when several instances are part of the same win.

Bonus Symbols Boost

This one can also activate totally at random. When this occurs, 1 to 3 bonus symbols are added to random positions of the reels, increasing the likelihood of entering free spins or awarding the bonus game directly.

There is also a chance for an additional set of 1 to 3 bonus symbols to appear after the first one has landed. If you manage to catch six bonus symbols in total, that triggers a special free spins mode and provides a 2,000x instant prize on top.

Free Spins Selection

Iron Bank 2 free spins start when at least 3 bonus symbols land on the same spin. Once the feature is activated, you are tasked to pick between three options – Mystery Symbol, Expanding Wild, or Multiplier Collect. Each option behaves differently in terms of volatility and extras, and the strength of the round depends on how many bonus symbols were involved in the trigger.

Three bonus symbols unlock the standard version of the round. Hitting four symbols upgrades it to the Super level, while five symbols open the Ultra level. A six-symbol trigger, in turn, awards the Ultra tier together with a separate 2,000x prize.

On any feature trigger, the Iron Bank 2 slot game might bless you with a Lucky Boost. When that happens, it means the current bonus round has increased odds of ending up with a big win.

Expanding Wild Free Spins

This round comes with 6 spins to start with, and most of the action revolves around reels 3 and 4. When a Wild symbol drops on either of those reels, it expands to cover that reel entirely and triggers a respin. As long as the respin produces a win, the wild on that reel gains +1x to its multiplier value. The values stay fixed for the rest of the bonus.

The upgraded versions pull more reels into the mix. In the Super tier, wilds that land on reels 2 or 5 don’t stay there – the game drags them into reel 3 or 4 instead. The Ultra tier widens the area of effect, activating reels 1 and 6 as well, so pretty much any wild around the board can be pulled into the centre pair.

Respins keep going for as long as you keep hitting winning combos. If a win includes both expanding wilds, their multiplier values are multiplied together. Another power-up that Super and Ultra tiers grant are increased starting multiplier values for those wilds – 3x and 6x, respectively.

Mystery Symbol Free Spins

This mode starts with 6 spins, and before anything begins, the game picks one symbol to act as the mystery symbol for the bonus round. Whenever that symbol lands on reels 2 to 6, it locks itself in place and turns into a sticky mystery symbol that stays for the remainder of the free games. On each spin, all sticky mystery symbols reveal the same matching symbol.

The higher tiers build on the same idea but give you a larger grid to work with. In the Super version, the reels gain an extra row, turning the layout into 5 rows and 6 columns. The Ultra tier adds two extra rows instead, giving you a 6×6 setup to collect mystery symbols on.

Extra spins can also be earned during this bonus. Once you’ve gathered at least six sticky mystery symbols, the game awards two additional spins. For every four mystery symbols added after that point, you receive another pair of spins.

Multiplier Collect Free Spins

This bonus starts with 7 spins, and stars with reels 2 to 5 highlighted. These reels come with coconut crates and special wilds that can pick up multipliers. Whenever a crate lands, it feeds a small counter sitting above that reel, usually adding between one and four coconuts at a time. Only one crate can appear per reel on any given spin.

Every time a counter reaches three coconuts, it increases that reel’s multiplier by +1x. These multipliers are applied to wild symbols that land on those reels. If a win uses more than one of these wilds, their multipliers are all summed up.

The round can run longer than the initial seven spins. When a counter fills up, one extra spin is added as well. This applies each time a coconut gun fills, so the feature can stretch out if crates keep dropping.

The upgraded versions tweak the start of the round. The Super tier guarantees that one walking wild reel shows up on the first spin, and in the Ultra tier, two of them are guaranteed. These walking wild reels move only between reels 2 and 4, and in the Ultra version they also avoid overlapping each other.

Bonus Bets

The Iron Bank 2 online slot game also includes a set of bonus bet options that change how the base game behaves. These are called Upgrade Spins, each boosting your odds of entering a free spins round.

The first one is Bonus Reels. This mode plays at 10x the normal stake and strips the reels of regular paying symbols, leaving only bonus symbols, with an increased bonus entry chance. The second option is Enhanced Spins. Here, the bet rises by 1.5x, and the game simply increases the likelihood of landing bonus symbols during regular play.

Buy Feature

Iron Bank 2 offers direct entry into the free spins feature, and the price depends on the tier you want to play. There are three different bonus buy options available:

• Normal Free Spins – 100x the bet
• Super Free Spins – 300x the bet
• Ultra Free Spins – 900x the bet

Theme & Graphics

On the outside, Iron Bank 2 looks as well thought-out as it is on the inside. The game drops you into a sun-drenched Cuban environment – a stylized Havana-like city where you join the cast of sharp-dressed animal criminals and law enforcement. The visuals are superb, heavily animated with comic book-style effects, and full of personality. Each free spins mode also comes with its own visual identity, shifting the backdrop and overall mood so the features feel distinct. Overall, an exquisite job by Relax Gaming, Iron Bank 2 slot looks dope.

Pros And Cons Of Iron Bank 2 Slot

Final Thoughts

Iron Bank 2 feels like a proper sequel to the original game. Relax Gaming took everything that made the first game stand out and built on it with more depth, more variety, and a much bigger sense of scale. The dual base modes, the layered free spins, and the overall unpredictability make every session feel different. It’s fast, volatile, and constantly active, yet nothing feels excessive or out of place.

Visually, the slot is spot-on – sharp comic-style animation, expressive characters, and distinctive settings for each bonus round give the game a ton of personality. The math model ties it all together, supporting the ambitious 50,000x potential without sacrificing balance. Altogether, Iron Bank 2 is a rightful continuation of a modern classic, and one of those releases that can easily keep players hooked for a long time.
