Description of the Slot 

A grand heist is about to take place in a Cuban city. The mastermind behind this daring plan is a man named Jaguar. Now you get the chance to forge an alliance with the famed criminal to rob the mighty Iron Bank!

Relax Gaming and Casinogrounds have jointly ventured into creating the popular slot, Iron Bank. The game opens on 6 reels and 4 rows and boasts an impressive 4,096 ways to win. The sheer appeal of Iron Bank rests with its abundant features offering incredible payouts. While base game actions appear randomly, you get your say during the bonus round. So, let’s see how well this heist is executed without waiting any further. 

Design and Audio

The slot’s action opens on a deserted Cuban street with the imposing Iron Bank standing on the grid’s left. The entire setting is designed like an oil painting and renders an exotic touch. In contrast to the colorful Cuban houses on the street, the reels look a bit drab and nothing extraordinary. 

While no one is present on the street, the chattering of people is faintly audible, probably coming from the bank. A pleasant guitar tune forms the background score with a touch of Cuban jingle. Overall, the design and audio are pretty good and showcase the calm before the arriving storm. 


Iron Bank hosts multiple features and modifiers available during the base game and free spins bonus round. 

Random Modifiers 

During the base game, one of the following symbols can randomly land on the reels: 

  • Scatter Symbols: 1 to 3 scatter symbols randomly hit the reels 
  • Mystery Symbols: a random number of mystery symbols land on the reels revealing the same symbol type  
  • Stacked Wilds: 2-5 reels fill with stacked wild symbols and provide a multiplier of 2x to 10x. If two stacked wilds are part of a winning combination, the multipliers multiply with each other.

Free Spins 

Landing 3 or more scatter symbols in a spin triggers the free spins bonus feature. If the number of scatters you hit is 4, 5, or 6, you also win an additional 20x, 200x, or 2000x the bet, respectively. The feature gives you 3 choices to choose from: 

  1. Mystery Symbols: You get 8 free spins with one random symbol taking the role of a mystery symbol. Anytime the chosen symbol lands during the bonus game, it becomes a mystery symbol and sticks to its position. On each spin, mystery symbols reveal the same symbol type. You win an additional free spin if a reel gets fully stacked with mystery symbols. 
  1. Expanding Wilds: You get 10 free spins in this option, and whenever a wild symbol lands in the two central reels, the symbol expands to cover an entire reel and also awards a respin. If the respin leads to a win, the wild multiplier increases by +1 and awards another respin with the winning wild remaining in its position. 
  1. Multiplier Collect: This option gives you 12 free spins, and reels 2 to 5 become eligible for accepting coconut crates. Whenever 2 coconuts land on a particular reel, its multiplier increases by +1. A progression meter is also placed above the reel. After accumulating 2 coconuts, one of the three notches in the meter becomes red. Turning all three notches red awards 3 extra spins. 

Buy Feature 

Clicking on this feature allows you to directly access the free spins bonus game by paying 100x the current bet. However, the bonus purchase feature might not be available in all regions. 


Iron Bank’s paytable consists of A to 10 royals that offer less than your bet amount. To rake in profitable payouts, keep an eye on premium symbols composed of cigars, liquor bottles, bananas, plant pots, and a literally bull-ish manager. These symbols offer payouts in the range of 2x to 50x the stake for landing six identical ones

The slot’s highest paying symbol is denoted by a bank vault and pays a staggering 2000x the stake for lining up six matched ones. However, with the aid of special features and modifiers, you stand a chance to win the max prize of 49,999x the stake in Iron Bank. 


Iron Bank slot is themed around a formidable bank in Cuba and a band of robbers led by the criminal mastermind named Jaguar. The lead anti-hero has devised a plan to pull up a heist in an attempt to empty the vaults of the Iron Bank. 


While the rewards for looting a bank are plenty, the risks involved are equally great. Therefore, it is no surprise that Iron Bank is a highly volatile slot. So, expect to see long, dry spells before a significant win falls your way.
