Iron Bank slot

Iron Bank slot by Relax Gaming, well I'm not sure what the theme is meant to be as we have high street artwork drawn behind the reels and characters including a fierce looking cheetah-human hybrid and angry bull featuring on them. The game has elements of Danger High Voltage slot built in along with Raging Rhino slot and believe it or not, Lil' Devil slot - all in one place! It's not hard to see where the inspiration has come from here, so can it be a big bank built here for our bankroll or will it be smashed with an iron fist?

On the reels...

There are 4096-ways to win on Iron Bank slot therefore we get 6 reels of 4 rows each with symbols stacked and single. The 6-of-a-kind pays aren't bad with the Bull at 50x bet, Banana 4x, Whiskey 3x, Cigars 2x and five card values paying 0.8 down to 04x stake for each full way. There are scatters on all reels in the form of Safes and you get 200x bet for 5 landing, or even 2,000x bet for all 6! The next important symbol is the Hybrid Wild which appears on all reels bar the first and can have some random effects as we will soon discover. Finally, we have Question Mark mystery symbols which can appear on all six reels, so now on to the modifiers.

Random Features

You can get one of three random event occurring on any spins:
Full Reel Wilds - the Hybrid Wild can expand when landing on any of the centre 4 reels and will display a multiplier of 2 to 10x, and if more than one lands these are multiplicative.
Mystery Symbols - the reels will darken when commencing a spin and Question Marks are overlaid with all landing in view converting to the same symbol including the Wild but not scatters.
Random Bonus Symbols - 1-3 Safe scatters added to the grid to increase the chances of a free games trigger.

Free Spins

You need 3 or more Safe scatters to be taken to a screen where the Cheetah-Human Hybrid appears in 3 different uniforms and you choose one for your bonus mechanic:
Blue, Mystery Symbol Spins - you get 8 spins and the game selects a symbol except Wild or Scatter. Each incidence of this on reels 2-6 becomes a sticky mystery symbol for the remaining spins. Fill a reel with them to earn +1 spin, therefore the maximum here would be 13 spins.
Yellow, Expanding Wilds - this is the most volatile one with 10 free spins. If the Hybrid Wild lands on reel 3 or 4 it will expand and award a re-spin. If the re-spin results in a win you get another and so-on. What also happens is that you get an increasing multiplier by 1x each time the Wild(s) are used in a win which resets once the re-spins end when there is no win. If you have this Wild on 3 and 4 at the same time, it will combine and display the aggregate multiplier for both i.e. 3x4 is 12x, 8x9 is 72x. It's all about getting continuous matches on the first 2 reels to get this multiplier up into the hundreds if both are in play!
Red, Multiplier Collect - 12 spins and now Coconut Crates are added to the centre reels which will fire 1-3 Coconuts up the top. This is vital, as above the centre 4 reels are meters consisting of 2 Coconuts and 3 bars. Each time the 2 Coconuts are filled in, the Wild on that reel will increase in multiplier by 1x if and when it lands. That's not all, as each time the Wild multiplier increases by 1x, a bar is filled in and when all 3 are filled, you get 3 extra spins awarded. This means each reel will award 3 extra spins when the multiplier reaches 3x, 6x, 9x etc. The Wilds are multiplicative like Raging Rhino, you want to get the dream spin where all 4 land in view!

Our View...

Iron Bank slot is pretty mundane looking it has to be said, with dull pastel colours that only spring to life during animations. The music and sound effects are pretty mediocre too, but the game mechanic cannot be faulted despite its construction from elements of other slots getting mashed together. I suppose the ingredients are there for any developer, it's how you put them together that makes or break a game. The RTP is 96.20% but if you use the 100x bet feature buy exclusively, rises to 97.00%. Your base game only produces big hits usually when the Wild multiplier reels occur or the mystery symbols are on all reels with a good symbol. The 3 free spins options though are all quite good, especially the Expanded Wilds one which can get very exciting when both 3 and 4 have them on with a high combined multiplier. If you like a bit of potential plus a longer feature to enjoy, choose the Multiplier Collect one which usually adds +3 spins at least once or twice. I can only recommend you to go ahead and try to break this Iron Bank....
