Iron Bank: Slot Overview

Game of Thrones followers may be a touch let down to discover Iron Bank isn’t actually about the icy, unfeeling financiers of Braavos. So, no hunting debtors across Westeros and no backroom bargains with dubious rulers. Instead, Iron Bank is a joint creation from developer Relax Gaming and Casinogrounds, a casino streaming community. As Casinoground’s CEO Tobias Svensen puts it, Iron Bank is ‘a slot based on our own experience, preferences and ideas.’

On the development side, casino streamer Kim Hultman, better know under his streamer name Letsgiveitaspin, told Bigwinboard.com:

“It’s been very rewarding and educational to be a part of creating Iron Bank. Instead of already having a concept like there was with the Dead or Alive 2 project, we, together with Relax got to create our own concept from scratch. We took a lot of inspiration from both streamers, the player community and existing games we praise and enjoy. On top of that we’ve added some fun elements like the “ZaKappa” and “Printing” which are frequently used in the slot community. We are eager to see what players will think of the game!“

Once it boots up, you’re greeted by a 6-reel, 4-row setup set in the heart of a Cuban city centre—Havana, most likely—right outside the Iron Bank itself. Enter the Jaguar, a criminal mastermind determined to empty the place of everything it has. Visually, the slot carries a slightly hazy vibe that suggests sticky island heat, and it recalls Relax Gaming’s bull-heavy La Fiesta. Both share a cheeky cartoon style and a hefty list of mechanics.

Iron Bank runs across all devices and lets you wager from 10 p/c to $/€20 per spin. As you’d expect from a streamer-led collaboration aimed at serious players, the volatility is high, scoring 5/5 on Relax’s dice scale. Even so, wins land fairly often—better than 1 in 4 spins, or 28.49% precisely. The RTP is solid as well: 96.2% in the default mode, increasing to 97% when the bonus buy is enabled. Add in the 4,096 ways to win, and the base game keeps moving smoothly while you wait for one of the three bonus rounds to arrive.

Symbol-wise, you’ll see 10-A royals, then cigars, rum bottles, gold bananas, plant pots, and furious bull bank managers. Landing six of a kind on premium symbols pays out 2 – 50 times the bet. The Jaguar acts as the wild in two variants—a regular 1×1 wild and an expanding full reel wild. In either form, he substitutes for any standard pay symbol to help complete wins.

Iron Bank: Slot Features

Iron Bank is packed with extras, including a couple of base game boosts, free spins, and one of the most coveted bonus symbols you’ll see. First up, in the base game, at the beginning of any spin, 1-3 scatter symbols may randomly be added to the reels before they settle, which greatly improves the odds of activating free spins.

At the start of a spin, random mystery symbols can also appear. After the reels stop, every mystery symbol changes to the same pay symbol. Also during the base game, there’s a chance to hit fully stacked wilds on reels 2-5, filling every position. These carry multipliers of x2-x10 and, when multiple stacked wilds help form a win, their multipliers multiply together.

Hit 3 or more bank vault door scatter symbols to launch the free spins feature. If you manage to land 4, 5, or 6 bonus symbols on screen, you also receive an extra 20x, 200x, or 2,000x the stake on top, respectively. After triggering, you’re offered three different free spins modes to pick from.

Option one is Mystery Symbols with 8 free spins, rated highly volatile (4/5). At the start, one symbol is selected to become the sticky mystery symbol. When these land on the marked reels 2-6, they turn into mystery symbols and stick in place. Each spin, they all reveal the same symbol. If an entire reel becomes filled with sticky mystery symbols, 1 extra free spin is granted.

Option two is Expanding Wilds, awarding 10 very highly volatile (5/5) free spins. Here, when wilds land in the highlighted area (the two middle reels), they expand to cover the full reel and a respin is triggered. Any win during a respin boosts the wild’s multiplier by +1 and awards another respi with the wilds remaining locked. If expanding wilds occupy both central reels, their multipliers are multiplied. Once no fresh wins land, the respins stop and the wilds reset for the next free spin.

The third option is the highly volatile (4/5) Multiplier Collect feature, which gives 12 free spins. In this mode, coconut crates can land on reels 2-5, raising a multiplier shown above each reel. After 2 crates are collected, the relevant multiplier increases by +1 and one segment on the meter lights up. Lighting all three segments awards 3 extra spins. When a wild lands, any multiplier on that reel is applied to it. If more than one wild multiplier contributes to a win, their values multiply.

It wouldn’t feel like a streamer-built slot without a feature buy. Where offered, you can pay 100 times the bet to enter the bonus and select whichever of the three modes you want to play. This bypasses the base game, although it also means you can’t land those potentially huge payouts tied to the bonus symbol.

Iron Bank: Slot Verdict

Relax Gaming describe Iron Bank as a ‘game for players, by players’—a line everyone uses, but here it fits better than most. The high volatility, sizeable win potential, and three separate purchasable bonus options make it especially stream-friendly, and you can sense that influence. The presentation is strong too: a polished blend of dreamy, exotic atmosphere and playful cartoon energy that works well against the ruthless math model underneath.

There’s no shortage of mechanics, so it may not be ideal for old-school purists who like things simpler. Everyone else is likely to enjoy the dense feature set and quick tempo, along with the possibility of landing genuinely massive wins.

Iron Bank isn’t trying to be a deeply refined slot, and it’s definitely not built around innovation. It plays more like a mixtape from slot fans, stitching together ideas from titles they probably love. For instance, you can spot shades of Pink Elephant (the main layout plus the random scatter trigger) and a touch of Lil’ Devil in the Expanding Wilds bonus.

And on that Expanding Wilds bonus: the way back-to-back wins keep handing out respins while ramping multipliers that then multiply together is a seriously powerful combination. Test results were respectable, though still far below the stated maximum potential of 49,998.8 times the bet. We’ve watched Money Train 2 break its 50,000x win cap, so it’s easier to believe Iron Bank could do something similar.

Relax Gaming and Casinogrounds have combined plenty of the right ingredients to make sure Iron Bank shows up in highlight compilations down the line. It won’t be for everyone, but the audience it’s aimed at should get exactly what they came for.
