3 or more scatter symbols trigger the bonus on Iron Bank, where players have the option to choose between 3 different bonus games. Visually, landing the bonus and making your choice adds some fun to this slot, with the corresponding part of the Iron Bank Blueprint being circled after the choice is made. Two of the bonuses on this slot seem like a new and interesting twist on some of the features we have witnessed on Big Time Gaming Slots before, such as Danger High Voltage and Lil’ Devil. There are 2 bonus games which are a 4/5 volatility level; Mystery Symbols and Multiplier Collect.
Mystery Symbols awards 8 free spins, with a symbol randomly chosen at the start of the feature, from within a folder, further adding to the theme and aesthetic throughout this slot. As with games such as Danger High Voltage, a lower symbol is the desired symbol, as there are more on the reels. Any time the chosen symbol lands on the reels, it is converted to a mystery symbol, marked with a question mark, and sticks on the reels. Each spin thereafter, all mystery symbols reveal the same symbol. Mystery symbols can only land on reels 2-6, and filling an entire reel awards one extra free spin.
Multplier Collect awards 12 free spins, and is perhaps the most confusing bonus game to understand at first. Across reels 2-5, coconut shooters sit at the top of the reels, and have a multiplier attached, which corresponds to any wilds that land on that reel. Coconut crates land across these reels, shooting 1-3 coconuts into the shooter at the top of the reel. Every 2 coconuts awarded increases the multiplier on the corresponding reel and wilds by 1, with the current multiplier visible both on any wilds that land, and at the top of the reel. Every time the coconut shooter at the top of the reel is filled, 3 additional free spins are awarded to players.
The most volatile bonus on offer is the Expanding Wilds bonus, which is reminiscent of Lil Devil, in an entirely different way. With this bonus, 10 free spins are awarded, where reels 3 and 4 are clearly marked as the area the expanding wilds can land. Wilds can still land on other reels, but are not expanding. Any time a wild lands on reels 3 or 4, they expand and players are awarded a re-spin, which continue as long as wins continue, or a second wild lands within the marked area. Any win during re-spins increases the multiplier by 1 on each expanding wild, and if both are in play they multiply together.
