Iron Bank

What do you get if you combine slick visuals and high-octane gameplay with hair-raising volatility and some explosive extras, all wrapped in an unusual theme and topped with an enticing top payout?

The answer lies inside this multi-layered video slot, the result of a collaboration between Relax Gaming and CasinoGrounds.

CasinoGrounds are considered one of the eminent streaming communities of the online casino industry, and have decided to pool all their collective knowledge, preferences and expertise into this highly enjoyable game that leverages state of the art technology from Malta-based B2B Provider Relax Gaming.


The game invites us to the unfamiliar dry streets of downtown Havana to be acquainted with Jaguar - a criminal mastermind who’s set his sights on robbing the nearby Iron Bank.

Surrounding the 6-reel, 4-row playing grid is a scene awash with soft pastels that evokes the laid back Cuban approach to life; the searing heat brought to life through its hazy appearance. Also listen out for the distinctly Cuban backing track, contributing to the communist vibe.

The reels are populated with lower paying royal symbols running 10-A, plus an assortment of premiums consisting of Cigars, Rum Bottles, Gold Bananas, Plant Pots, and Raging Bulls. The latter, bizarrely, serves as the Bank Manager - perhaps explaining his furious appearance, and dishing out wins worth 50x your stake should you catch him in a good mood.

Gameplay & Features

Matching symbols in any position across three or more adjacent reels, starting from the leftmost reel, constitutes a win in Iron Bank.

Jaguar serves a dual purpose in the game, as both a standard 1x1 Wild, plus an Expanding Wild capable of covering entire reels. Both functions see Jaguar step in to replace all regular symbols to assist in win-making opportunities.

Free Spins

Free Spins are undoubtedly the star attraction in Iron Bank, triggerable by catching at least 3 Bank Vault Scatters during a spin. This prompts you to choose from one of three options, each offering varying degrees of volatility:

  • Mystery Symbols (Volatile): 8 Free Spins. 1 symbol is chosen at random to become the sticky Mystery Symbol. When landing on reels 2-6, these then remain sticky for the duration of the round. On each spin, these reveal the same symbol and when an entire reel is covered in such symbols, you get 1 extra spin.
  • Expanding Wilds (Very Volatile): 10 Free Spins. Wilds expand to cover whole reels when they land in a highlighted area, and one Respin is awarded. Wins during respins increase the Wild multiplier by 1, and another respin is handed out while Wilds remain locked in place. Multiplier values are multiplied whenever Expanding Wilds occupy middle reel positions, and respins end when no new wins form.
  • Multiplier Collect (Volatile): 12 Free Spins. This option sees coconut crates increase a reel’s multiplier value when they appear on reels 2-5. After 2 crates are collected, the corresponding multiplier increases by 1, while the meter is filled up by one bar. 3 extra spins are also up for grabs by filling the meter entirely, and Wilds can bring further multiplier values whenever they make an appearance.

Feature Buy

Of course, this being a slot produced by avid slot players, Relax Gaming have bolted on a Bonus Buy feature - increasingly making its way into a growing number of new slot releases and favoured by a large proportion of more serious players who don’t want to hang around tirelessly hoping to trigger the feature organically.

For a fixed fee of 100x your wager, you can bypass the normal base game requirements to initiate the feature instantly.

Iron Bank on Mobile

Anyone that prefers to fire up slots while out and about can enjoy Iron Bank safe in the knowledge the game is compatible with just about every modern gaming device on the market.


As you might expect from a game inspired by a bunch of hardcore gamers, Iron Bank has been given the most extreme variance setting and as such is geared especially towards players sharing their own volatile tastes.

Don’t forget, the bonus buy option provides the chance for some welcome relief if you’re reeling from the constant stream of near misses and fancy a quick shot at the juicier prizes on offer.

The Verdict

Iron Bank is one of the more original slot offerings of 2020.

The two main parties involved in its creation decided to go off in a different direction for the heist-themed game. Indeed, downtown Havana is not the first place you would think to set a slot of this type. But CasinoBeat’s streamers are some of the best for a reason, and certainly know a good game when they see one. Added to the expert acumen of leading software house Relax Gaming, the result is an impressive confluence of ideas, designs and gameplay that make for some absorbing slot action - not forgetting its considerable top prize.

We look forward to seeing what other exciting projects the slot community have up their sleeve over the coming months!
