Relax Gaming will have you reach for a sofa as you load the Iron Bank slot on your mobile device. The game puts you on the path with Jaguar, a mastermind bent on exploiting the bank in not-so-legal ways. Whether he succeeds or not is entirely up to you as you get the reels spinning. Available now in sweepstakes casinos, this slot machine gives you the chance to win real money while playing for free.

Free spins and expanding wilds are not new in online video slots, but grabbing sticky symbols is always a plus. Iron Bank brings sticky characters to its base and bonus rounds, increasing the intrigue even further. Let’s step on the gas and explore this title from Relax Gaming if your ride is all fueled up and ready to go.

Gameplay and Mechanics

Iron Bank Slot Relax Gaming – Landing

The calm music sounds suspicious as you stare down the 6-reel, 4-row online sweepstakes slot. You’ll get an idea of the symbols before you hit the spin button. Then, the reels will go into a frenzy as the symbols spin across the reels.

Relax Gaming is a generous game provider, giving this slot 4,096 paylines. That is intriguing, although the number is lower than the Megaways games. Still, winnings will come when you have at least 3 matching icons across three adjacent reels.

All winning combinations begin on the leftmost reel. Of course, you will get the highest prize for each symbol when you have 6 on a payline. Speaking of which, the game features an array of familiar and creative icons.

If you want flexibility, there is a turbo option and an autoplay button. Also, you can skip the hassle and grab free spins with the bonus buy option. Things become dramatic when the bonus round kicks in.


At the lower end are the A–10 playing cards we often see on slot machines. There is no out-of-the-ordinary design, as Relax Gaming stuck to their functions rather than aesthetics. These lower-paying icons pay from 3 on the reels to 6.

A box of cigars, a bottle of whiskey, a banana, and a plant pot appear as the mid-paying symbols. They have decent payouts but are far from what the neatly dressed buffalo offers. The latter is the highest-paying of the bunch, providing substantial value if you land six.

The bonus symbol pays out if you land four, five, or six. It also has the highest single-icon payout in the game.

Bonus Features and Special Symbols

Relax Gaming certainty kicks relaxation out the window with the bonus features in this slot machine. The intrigue will keep your heart racing in a rhythm that matches the game’s soundtrack. Landing the bonus symbol on the reels triggers this magic, but what it brings will surprise you even more.

We’ll mention several special symbols as we review the bonus features. With that in mind, here are the bonus rounds in Iron Bank:

Random Mystery Symbols

These hidden icons can reveal any symbol when they appear on the reels. They’ll stay hidden until the spin comes to a stop. Then, they will show the same character.

Having them up there might sound like little, but their appearance increases the chances of a winning combination. Moreover, they play a similar but spiced-up role during free spins.

Full Reel Wilds

Jaguar is the wild symbol in the game, and you might see either its head or entire body. The latter occurs when the icon covers an entire reel. Also, it brings multipliers that boost the payout if it is part of a winning combination.

The multipliers range from x2 to x10, and they appear randomly. They’ll multiply each other if you have multiple full-reel wild symbols. Notwithstanding, the wild character can only appear on the second, third, fourth, and fifth reels.

Free Spins

Iron Bank Different Bonus Rounds 

Now, to the icing on the cake. The free spins round pops up when you land 3 or more bonus symbols on the reels. Furthermore, you can pick any mode from the three modes that appear.

Each mode comes with different dynamics, although the gameplay remains the same. They are as follows:

  • Mystery symbols: We mentioned them earlier, but they perform an even more significant role during free spins. Picking this mode gives you eight extra spins with a randomly selected sticky mystery symbol. These symbols will convert to the mystery icon and stick on the reels.
    They can only appear on the second through sixth reels. They’ll remain sticky and reveal one symbol at the end of each spin. In addition, filling the reels with the sticky mystery character will give you an extra spin.
  • Expanding wilds: This mode gives ten bonus spins with marked third and fourth reels. The wild icons on these reels will expand and add a random multiplier. Each win increases this multiplier value by one.
    The wild symbols will also cause a respin and continue increasing their multipliers. Their values will multiply each other if they form a winning combination. You’ll keep getting respins, provided you have winning combinations or land a second wild icon on the market reels.
  • Multiplier collect: This game still has one more feature up its sleeves. This bonus round adds 12 spins with multipliers on the reels. However, you need two coconut crates to increase the multiplier values of the wild symbols.
    You can continue winning with the multipliers while the coconut crates fill the progress meter. Once it’s filled, you’ll receive three additional spins to continue the bonus round.

Buy Feature

This option is available on the main screen. It costs 100 times your stake, but you get the free spin modes. Then, you can pick one and continue into the bonus round.

Design and Graphics

The soundtrack quickly introduces players to the bustling city behind the reels. Things look hazy as you look out at the horizon, but the Iron Bank stands boldly on the left. You’ll even find the inscription at the top.

How Good is the Design of Iron Bank Slot?

This online video slot’s graphics are not mind-blowing per se, but we appreciate the minimalistic design. The colors pop when they need to without being constantly in your face. They remain subtle throughout the gameplay.

The graphics change during the free-spin modes to reveal different sections of the iron bank. You’ll find the tunnel, office, and frontal assault. Then, you’ll get some shooting ball animations for the progress meter and free spins.

The reels have slight modifications during free spins, but the structure remains unchanged. New symbols join the fray to keep the intrigue flowing.
