Iron Bank Slot Review

Last updated: 31/03/2021

Players had the final word when it came down to Iron Bank's features and preferences. Instead of using a familiar concept, Casino Grounds and Relax Gaming decided they’ll start from scratch and set up a new standard in online slot development. They took a lot of inspiration from the streaming community and existing games they admire. Familiar phrases such as "ZaKappa" and "Printing" are often used among players, so with this game, developers decided to bring the community closer to new, potential fans.  

About Iron Bank Slot 


Have a virtual trip to the Caribbean coast for an exciting gameplay experience from Relax Gaming. In a setup that looks and feels like Havana, the Iron Bank slot handles a bank heist theme loaded with a pack of modifiers and symbols. Each bonus round represents a different plan for itself, and in some ways, it lets you decide how you want to proceed with your game. This online slot game is more than just thrill, rum and cigars - the free spins modes can win you up to 49,999x your bet. 

The Iron Bank slot comes with a minimum stake of £0.10 to £20 per spin. The volatility is high, ranked 5/5 on Relax Gaming’s metre, and the winning ratio stands at 28.5%. When combined with the winning combos, thе base game meets the expectations along with the triggered bonus rounds. The overall slot action revolves around the mystery symbols and three different free spins options packed with sticky wilds, multipliers or expanding wilds. We'll go through their details in a bit, now, let's look at the graphics, symbols on the reels and their value. 

Design, Symbols and Graphics 

Loading the Iron Bank Slot will take you to a sunny Cuban street where you can still experience the feel of the 20th century. You’ll notice the colourful bank building on the left, which fits great into the theme. Few authentic elements populate the reels as symbols, such as the Cuban cigars and rum bottles. The typical Cuban music and the chattering from locals add a nice touch to the atmosphere.

The top regular symbols on the paytable include a gold-plated banana, a pineapple, a cigar box and an angry bull. Of course, the list of standard symbols is completed with 10 to A card royals, with the Jaguar Wild and Vault Door being the special symbols that substitute the regular ones. The bull is the most rewarding symbol on the reels, winning you 50x your bet for 6 of a kind. The vault door is the scatter symbol that triggers the free spins round where you can choose one of the three options on offer. Moreover, you'll also boost your score with up to 2,000x your bet if you manage to trigger the bonus game with 6 vault scatters, which is impressive. 

RTP, Variance and Payouts for Iron Bank Slot 

The gameplay takes place over 6 reels with 4 fixed rows of symbols, with over 4096 ways to win. The RTP stands high at 96.2% and increases up to 97% during free spins. At first glance, there’s nothing new in terms of the mechanics. However, the setup looks and feels wholesome and innovative. There’s a lot for you to explore, as the list of features include regular and expanding wilds, mystery symbols, scatters and three free spins variations.

Gameplay and features on Iron Bank Slot 

Even though the setup is quite familiar, Iron Bank is not short on new features, offering game extras, bonus symbols and free spins. If you land 3 or more vault door symbols, you’ll trigger the free spins round that comes with three bonus features. You can opt for random mystery symbols added on the reels which transform to reveal the same matching symbols. You can also land multiplier wilds that cover the reels from 2 to 5, and the multiplier value is ranging from 2x to 10x your bet. Here’s more about them:

Random Mystery Symbols 

During spins in both the base and bonus game, you'll notice that random question mark symbols are added to the reels. These are the mystery symbols that have the ability to transform into one matching symbol and boost your total. When the mystery symbols are revealed, the system does a new payout calculation.

Expanding Wilds 

The Jaguar is the wild symbol in the Iron Bank slot and appears on reels 2,3,4 and 5. As usual, wilds substitute all regular symbols to form a winning combination. Besides this, the Jaguar Wild lands with a multiplier attached to it that can go up to 10x your bet. if you're lucky to land more than one wild on the reels, their value is multiplied. For example, if you land wilds with x3 and x5 multiplier, you'll boost your payout with x15 your bet. 

Free Spins 


This feature is activated once you land at least 4 scatters on the same spin. If you manage to trigger the feature with more than 4 scatters, you'll land an award in a form of a payout booster. So, for 4, 5 and 6 scatters you'll get 20x, 200x or 2,000x your bet respectively. Then, you'll get to pick one of the three free spins options on offer: 

Mystery symbols

If you choose this option, you’ll receive 8 free spins. Before you start spinning, one symbol will be randomly chosen to be the mysterious one. When this appears on reels, it becomes a mystery symbol locked in that position until the end of free spins round. If you fill one reel with mystery symbols, the gameplay adds 1 bonus free spin.

Expanding Wilds

This option offers you 10 free spins. If you get a wild symbol on reel 3 or 4 it expands to fill the whole reel, while bringing you an extra spin. Any winning combo increases the value of the multiplier wild by 1. If you land wilds on both reel 3 or 4 their multiplier values combine.

Multiplier Collect

Here, you can get 12 free spins. For this one, you’ll need to collect coconuts above reels 2 to 5, and this increases the multiplier displayed above each reel. A boost to the multiplier happens for every 2 collected coconut crates. If you fill the progress meters, you’ll earn +3 free spins.

Iron Bank on Mobile 

Iron Bank is available and optimised to play on all devices, including desktop and mobile. The pastel tone and branding look very modern, even when playing on a small device. Features load fast, and bonus rounds work perfectly on whichever device you prefer. In general, the Iron Bank mobile version works quite well.
