Iron Bank Slot RTP, Details & Wager Limits

The Iron Bank slot is played on 6 reels, 4 rows and 4,096 ways to win. To create a winning combination, land 3 or more matching symbols or wilds on adjoining symbols, starting from reel 1.

You can try and break the bank here at stake levels that start at 10p per spin and rise to a maximum of £20 per spin. There’s an Autoplay function where you can choose 10 to 1,000 autospins or even an infinity option. You can also add loss limits, win limits and single win limits.

This heist-themed slot is a high variance one. The Iron Bank volatility is extremely high. We’re in proper 5 out of 5 territory here. High risks can mean big rewards though. The max win is 49,868 x your total stake which is high.

The hit frequency rate is 28.49% so you can expect to land a winning combination less than a third of the time on average. The Iron Bank RTP is 96.2% which is a solid rate. If you use the Bonus Buy function, the RTP increases to 97%.

Iron Bank Theme – Audio & Design Features – go on a heist in Havana


With a bank heist theme, there’s a sunny, salsa-style to the design in the Iron Bank slot game. The pastel coloured buildings of a Havana street are the setting here. The visuals here are terrific. So too is the Cuban-style backing track. There’s no shortage of atmosphere here.

By the way, there was an Iron Bank in Game of Thrones but the Iron Bank here is set in Cuba and your goal is to make off with its loot alongside an animal criminal mastermind known as The Jaguar.

Joining the rather retro A to 10 royals are Havana cigars, bottles of rum, a gold banana and a gemstone pineapple. The most rewarding standard symbol is the bull which pays 1, 3, 10 or 50 x stake for 3, 4, 5 or 6 in combination.

They’re joined by animal criminal mastermind the Jaguar which is the wild. This has expanding and multiplier powers too which we’ll look at in detail below.

Iron Bank is available to play on all devices including desktop, tablet and mobile. The pastel style visuals are lovely to look at, even when playing on a small screen device. The features stack up whatever you’re playing on. Overall, the Iron Bank mobile slot works very well.

Iron Bank Bonus Features

This bank heist comes with a good array of extras that can help you get hold of the elusive loot. Spicing up the base game are mystery transforming symbols and stacked wilds with multipliers. Trigger the bonus and you’ll have the pick of 3 different free spin features, complete with a special modifier which is active throughout.

Random Mystery Symbols feature

On any spin, you could see a random selection of ? symbols added to the reels. These all then transform into the same matching symbol. A new payout calculation then follows with the newly transformed symbols in position.

Full Reel Wilds feature


These fully expanded wilds can hit on reels 2 through 5 only. Known as the Full Reel Wilds feature, they substitute for all the standard symbols as per usual. More importantly, wild reels also come with a multiplier of between 2x and 10x attached.

Even better is if you land more than 1 full reel wild in the same spin as their values are combined. For example, full reel wilds with 2x and 10x multipliers attached would send the payout rocketing by 20x.

Random Bonus Symbols feature

At the start of any base game spin, the Random Bonus Symbols feature can be triggered. 1 to 3 bonus symbols can be randomly added to the reels which increases your chances of triggering the free spins.

Free Spins feature


Land 4, 5 or 6 bonus symbols anywhere on the grid on the same spin and you’ll pocket an award equal to 20, 200 or 2,000 x your total stake. You’ll also trigger the Free Spins feature round where you’ll be offered the pick of the following 3 options:

  • Mystery Symbols: choose this option and you’ll receive 8 free spins. Before they start, 1 symbol is randomly chosen to become the sticky mystery symbol. When this appears on reels 2 through 6, it becomes a mystery symbol and will lock in that position for the remainder of the round. Fill a whole reel with sticky mystery symbols and 1 extra free spin is added to your total. This is a high variance option.
  • Expanding Wilds: on offer here are 10 free spins. Land a wild on reel 3 or 4 and it expands to fill the whole of that reel. It also awards a re-spin. Any win increases the value of the multiplier attached to the expanding wild by 1. If both reels 3 and 4 contain wilds, their multiplier values combine. The re-spins continue as long as there’s a winner on show. This is a very high variance choice.
  • Multiplier Collect: this option delivers 12 free spins. Look out for special coconut crate symbols. When these land on reels 2 through 5, they add a coconut to the meter above that reel. Fill a meter with 2 coconuts and it increases the multiplier attached to the wild by 1 when it lands on that reel. Once again, multiplier values can combine. You can add more free spins to your total here too by landing coconut crates. This is a high variance feature.

You also have the option to use the Buy feature. For a cost of 100 x your total stake, you will be presented with the 3 free spins options outlined above. If you do buy your way into the free spins, the RTP will increase to 97%. This feature isn’t available in the UK though.

Iron Bank Review Summary – this Cuban adventure packs a high variance punch 

It makes a refreshing change to head to Cuba rather than China or Egypt for an online slot. The design in the Iron Bank slot is very appealing too, combining lush visuals with a toe-tapping salsa soundtrack.

The gameplay impresses as well, offering enough variety to keep things interesting without going too over the top. The key to big wins is from the multipliers which come from the Full Reel Wilds feature or from the Multiplier Collect and Expanding Wilds free spins.

Don’t be tricked into thinking this this isn’t a fiery slot though. It most certainly is. The volatility here is extremely high. Another game you should consider is the Money Train 2 slot by Relax Gaming which is their most popular title.
