Relax Gaming is not the game producer we write about the most here at Slottomat. But when games appear with the next 50,000x bet in potential winnings and high RTP, this of course attracts attention!

The game has its setting in Cuba in the 1970s with atmospheric music and great gameplay. Join emptying the bank vault with three robbers that you can summon at any time in the game to help you!

If you like games of this type, you can also try out Microgaming's The Vault on our website.


The online slot has many different symbols you can associate with Cuba with a little twist. The bank manager is a bull with a banana cigar and Rom naturally looks a little angry because the bank is being robbed. The thugs in the game are only included during free spins, which you can buy at any time. Here are the values ​​of the symbols in the main game

  • Bank Vault- Provides up to 200 x bet with 6 of a kind in a payline
  • Bull- Gives up to 5x bet with 6 equals in a payline
  • Perfume- Provides up to 1x bet with 6 of a kind in a payline
  • Banana Cigar- Provides up to 0.4x bet with 6 of a kind in a payline
  • Space Bottle- Provides up to 0.3x bet with 6 equals in a payline
  • Cigar Box- Provides up to 0.2x bet with 6 of a kind in a payline

You can also use the familiar deck of symbols from 10 to ESS which gives maximum payouts from 0.04- 0.08 x bet in winnings. Here we are talking about very modest payouts in the main game, apart from the vault door which gives a massive win.

Game Setup

The symbols roll in on an extended 6x4 reel layout that gives you up to 4096 paylines on every single spin. These lines are not possible to adjust, so that's why the payouts are so low in the main game as well, in that you quite often hit small payouts during the spins. But unfortunately, this is usually not enough to cover what you have lost in previous rounds.

Relax has put in many opportunities to adjust bets on Iron Bank with 15 different bets between € 0.1- 20 per spin. These are actually realistic sums that players can afford to spend as well.

Bonus Features

  • Bonus Purchase This is probably the most important feature of the game where you can bet any winnings you get in the main game to buy free spins with lots of different helpful features. You start with 10 free spins and you have three different game options:
  • Multiplier collect The three middle wheels get a multiplier above the wheel. These increase when you land so-called multiplier symbols on these reels. When you reach 3x multiplier on one of the reels, you also get 3 more free spins.
  • Expanding Wilds In this bonus feature you can land wild symbols that expand to cover the entire row it lands on. The symbol stays there as long as you land a win on the pins. For each round it stays on the reels you get 1x multiplier in addition. The larger the multiplier is (over 3x) the more spins you can afford to lose, as the multiplier first decreases in value before it disappears completely.
  • Mystery Symbol for every free spin you get, the number of mystery symbols on the reels increases. You start with two on the first spin, and end up with 10 at the end if you land winnings during the spins. The mystery symbol is completely arbitrarily placed on the reels, and with a completely arbitrary value.

Win Potential

There is definitely money to be made at the Iron Bank online slot. If you land the highest paid symbol with the highest multiplier in the bonus game, well then you are sitting with a jackpot of 50,000 x bet in your lap. This then corresponds to 1 million euro if you play with the highest bet. The bonus purchase feature is quite expensive at the 10 x bet you want during bonus rounds, so choose this carefully when you feel you can afford it.

Iron Bank Verdict

You can play Iron Bank for free here on our website, and you will quickly see if this is an online slot for you. If you buy a bonus, we recommend that you stick to Expanding wilds or Multiplier collect, as these usually bring in more money. On online slots, of course, there are no guarantees of winning, but this feature is very fun to watch and is quite affordable compared to other bonus online slots out there.
