Iron Bank slot review Relax Gaming mystery win

Iron Bank slot – Gameplay and Features

Iron Bank slot has a 6×4 setup, and there are 4,096 ways to win (according to the win all ways principle).

The highest paying symbol is a bull with a suit, and I bet he’s the bank’s CEO. A six-of-a-kind of bulls yields a 50x win.

Medium-paying symbols are a plant pot, a banana, liqueur, and cigars box, and the four low-paying symbols are the 10, J, Q, K and A.

The scatters (bonus symbols) are iron, safe doors. If you manage to spin a six-of-a-kind, you’ll get a blasting 2,000x win!

Features in the main game – random mystery symbols and full reel wilds

Occasionally, several random mystery symbols appear on the screen. You’ll find out into which symbol the mystery symbol is transformed at the end of the spin. In all cases, the symbols are identical, and with the win-all-ways mechanic, that can be very convenient!

It’s also possible to land full reel wilds (fully stacked wilds) on reels 2 to 5. These also get you an x2 to even an x10 multiplier. And these multiply each other!

Iron Bank slot review Relax Gaming win spins

How do you get access to the free spins?

You need at least three scatters to activate the free spins.

It is also possible to use the Bonus Buy feature at the cost of 100x the original bet. Perfect for high rollers.

The free spins – you can crack the bank’s safe in 3 different ways

You may choose which option you play. The best thing is to try these all, at least once. Allow me to explain the three options.

OPTION 1: MYSTERY SYMBOL. You get to enter the office of the bank (infiltrate office). You get 8 free spins, where you’ll find out what the mystery symbol will be. Now it’s a matter of spinning many mystery symbols (and preferably on the leftmost reels). The nice thing is that these symbols remain sticky for the remaining free spins.

OPTION 2: EXPANDING WILDS. You get entrance via an underground tunnel (secret tunnel) to crack the safe. You get 10 free spins, and now you benefit from the full reel wilds. Once you have an expanding wild and also a winning combo, you get a free respin. And the wild multiplier goes up by +1. It is the most volatile option.

OPTION 3: MULTIPLIER COLLECT. Here you use coconuts to attack the bank (frontal assault). With coconuts, you collect wilds with multipliers (on the middle reels), and these also get you extra free spins. It’s an option with lots of fireworks! You have 12 free spins here.

Payout percentage (RTP)

The RTP is 96.20%. It’s okay, but not exceptionally high. However, if you use the Buy a Bonus feature, the RTP is an excellent 97.00%.

The variance (volatility) of the Iron Bank slot is exceptionally high

I do not doubt that it is, once again, an extremely volatile slot. With those multipliers and stacked wilds, wins can be very, but very massive.

I’m not surprised anymore if the top wins exceed 10,000x. Soon, my top 10 list of the most volatile slots games will only have Relax Gaming slots!

Pros en Cons



  • The gameplay has lots of variety, thanks to the many features and three different free spins.
  • An attractive theme, and it feels like you’re in Central America.
  • Towering win potential.
  • The Buy a Bonus feature always comes in handy


  • Very risky (and addictive), and if you can’t control yourself, it can be an expensive evening!
