Iron Assassins Slot Review

The Iron Assassins slots game can be found at casinos offering Spinomenal software. Spinomenal is one of the newer software developers in the online gaming market. Alongside many of the smaller casino software providers Spinomenal focus heavily on slots games. The House Edge/RTP of the Spinomenal slots games is listed within the paytable for the newer games in their catalogue. For the older games, as Spinomenal is partnered with UK licensed operators and the UKGC license requires the publication of this information, RTP figures can be found on numerous casino sites. As such, we know that the house edge for Iron Assassins is 4.25%.

Iron Assassins is a 5 reel game that is 3 symbols high. The game uses 30 standard paylines, playing from left to right.

Special Symbols

Wild – The Wild symbol is the “Green Spaceship”, with Wild written on it and will substitute for all symbols other than Free Spins and Bonus symbols. There are 3 different versions of this in the main game and the Free Spins, all looking a little different to each other:

Sticky Wild –The Wild will stick in place for another turn and you will be given an additional Free Spin. During the Free Spins feature a new target will not be added when you are given an additional spin.

Wild Multiplier – A multiplier will be added to any winning lines in which the Wild is present. x2, x3, x5 or x10 multiplier will be added to any wining payline. The size of the multiplier is chosen at random.

Wild Generation – The Wild Generator will transform one randomly chosen symbol on the board into another Wild. This can create a chain effect of up to 3 Wilds generated in a single turn.

Free Spins – The Free Spins symbol is a “Blue Spaceship” with Free Spins written on it. 3 or more of them will earn you 7 Free Spins at x7 the bet. These are only available during the main game.

Bonus – The “Alien” symbol is the Bonus symbol. 3 or more will trigger the game’s main Bonus feature.

Bonus Features

Moving Targets – This feature is only available during the main game. At the start of the game you will notice a red target covering a symbol in the bottom right hand corner of the grid. With each spin it will move one space to the right and then work up to the next row. If the target land on top of a wild symbol a unique Wild feature will be triggered.

Multi Targets – This feature is only available during the Free Spins. Every time you take a new free spin a new target will be added to the reels and will stick in place until they are finished. The same unique Wild features present in the main game are also in play during the Free Spins, except this time there are more targets on the reels.

Bonus – If you trigger the Bonus feature by revealing 3 or more of the “Bonus” symbols you will be taken to a new part of the game where flip and reveal feature is waiting for you to reveal cash prizes. In this instance the tiles take the shape of some evil looking aliens and the flipper is your laser gun that you use to shoot them.


Iron Assassins is a venture into science fiction. A world in which giant robots, spaceships and space stations are needed to protect humanity from the influx of some creepy looking aliens. The game is trying its hardest to look good and with a bit more fuel in the software capacitors I have no doubt that it really would be an amazing looking bit of gear. There are plenty of features to keep you amused. The moving target means that there is always something going on alongside the spinning of the reels. The multitude of wilds means that there is plenty of variety in the game, which means you’re unlikely to get bored any time soon. The game’s biggest let down is the house edge. This is something that Spinomenal are normally brilliant at but in this instance, at over 4%, Iron Assassins could be offering much better value for money than it does.
