Io Features & Bonus Games
Step into the casino space station with Io and trigger bonus scatter symbols, a progressive multiplier and other great features leading to valuable minerals.
Laser
When the laser beams from two laser symbols intersect, then the laser symbols and all regular symbols along the beams are turned into wilds. A single laser symbol removes itself and all regular symbols along the laser beam.
Wild Forge
A Wild Forge will fill an empty space below with a multiplier wild. The value of the multiplier increases every time the Wild Forge is used. The Wild Forge turns into a regular multiplier wild when it falls to the bottom.
Wild Symbol
The regular wild symbol substitutes for any regular symbol. A winning combination of all wild symbols pay as the highest value symbol.
Avalanche
All symbols that form part of a win, apart from charged wilds, are removed and leave space for additional symbol drops. An additional row of symbols is added at the top. You can get up to 8 rows of symbols. The avalanche feature continues until no new winning combinations appear.
Charged Wild
The charged wild symbol comes with 4 additional lives. It spends a life when it forms part of a win. The charged wild can substitute for any regular symbol.
Bonus Game
You need 3 bonus scatter symbols to trigger the free drops bonus game. The free drops spins bonus cannot be retriggered. The free drops bonus game is played with 8 rows. Charged wilds and wild forge symbols are collected at the bottom between free drops.
Bet Sizes, Max Win, & Return to Player (RTP)
You can play the Io slot game with your bet level set between 0.20 and 100.00 per game round. During the base game and bonus features, a random number generator (RNG) is used to ensure fair outcomes on every spin.
