START TO PLAY FOR MONEY

IO slot is an ELK Studios space-themed game built around gravity rather than standard falling reels. Symbols slide left and right on their way down, so more of the grid can come into play after each drop. The game starts with 4,096 ways to win and can expand up to 8 rows with 262,144 ways. The Laser symbol clears symbols in the direction it points, and if two lasers cross, every symbol in their path becomes Wild. Wild Forge fills the empty space below it with a multiplier Wild, and that multiplier grows each time the Wild Forge helps create a win. Charged Wilds are stronger than regular Wilds because they carry four extra lives and lose a life only when part of a win. The bonus gives 7 Free Drops on an 8-row grid. RTP is 96.0%, volatility is 8/10, and the max win is 500,000 coins.
