Iron Assassins

Iron Assassins is a sci-fi slot in which an elite squad of combat robots defends a spaceship from an alien invasion. Spinomenal builds it on five reels, three rows and 30 paylines, with coloured robots and a fleet of spacecraft as symbols and medium volatility.

The wild is the key piece: as well as substituting, it applies a multiplier of up to 10x to any win it completes. Three or more scatters award 7 free spins plus up to 3x the total bet, and three bonus symbols launch an interactive shoot-out in which every alien destroyed reveals a cash amount. RTP is 91.62 %, stakes range from 0.5 € to 200 € and the maximum win is 31,200 €. Iron Assassins suits players who like action and arcade-style bonus games.

Three matching symbols on any of the 30 lines pay. Robots in different colours form the premium set, led by the blue robot at 500 coins for five; three-of-a-kind wins in this tier start at 12 coins. Spaceships are the lower-value symbols, paying 12 to 50 coins. Coin values range from 0.01 to 10, and autoplay can be used.
