Explore the Casino Space Station

Embark on a journey around the solar system when you play this space themed slot machine. IO online slot draws you to Jupiter and gives you more than your average win in the process. You’ll the see planet in the background from your spaceship filled with brightly colored symbols.

The highest paying symbol is the 7, and promises a win of up to 1,000x your stake. This is followed by a diamond, a clover and a star. The IO slot machine lower paying symbols include A, K, Q and J symbols respectively.

You’ll also see a W, which represents the wild, and a planet with BONUS written across it.

Shoot for the Stars

Get ready for take off when you place your first IO online slot bet. You’ll get to select between bets of 0.20 and 100.00. Winning paylines go from left to right, and should you land more than one during a single spin, only the highest one will be paid.

We’ve collected payouts based on a 100.00 coin bet below. Keep in mind that the IO slot machine wins vary depending on the bet size. The higher your stake, the higher your winnings. You’ll find the numbers corresponding to your bet choice in the game’s paytable.

Your payouts, can, however, vary if you choose a Bet Strategy. You can find these by clicking on the coins symbol to the left of the screen, but here are the basics:

Optimizer: your bet level will adjust automatically according to your chosen percentage
Leveller: your bet will be raised after five consecutive losses, and reset after a win
Booster: raises your bet by one level after a loss, up to a maximum of four times
Jumper: increases your bet by one level after a win, up to a maximum of four times

IO slot machine comes with an RTP of 96.00% and medium to high volatility, which can only mean big wins!

Charge your Wilds

Bet strategies aren’t the only cool feature IO online slot has to offer. Besides your regular wild symbols substituting for any other symbol, you’ll come across lasers, charged wilds, wild forges, a gravitational bonus game and more.

You’ll start off with four lines when playing IO slot machine. When you land a win, the Avalanche feature is triggered. All winning symbols blast away, making room for the remaining symbols (except the Charged Wilds) to fall into the empty spaces. You’ll be awarded with new symbols, and a new row. This repeats itself with every win, but you can only get a total of eight rows.

The Charged Wilds have an electric current around them. It works the same as a regular wild but has a total of four lives. It loses a life every time you land a win.

The Wild Forge, on the other hand, fills the empty space below it with a multiplying wild. Each time you use this, the multiplier value increases. This will turn into a regular multiplier wild when it hits the bottom of the IO online slot grid.

You’ll also see a Laser beam while you’re spinning. Watch the laser shoot and remove itself and the symbols it touches from the grid. Get two of these in opposite each other and the symbols in their path will transform into wild symbols.

And let’s not forget about the IO slot machine Bonus Game. You’ll need three or more bonus scatter symbols to get to this round, and it can be retriggered within itself. Played with eight rows, you’ll get free drops, Charged Wilds and Wild Forges at the bottom of the grid to give you an up to 500,000 win!

Explore the Universe Some More

Take a detour and check out some of the other space themed slot machines. We recommend the Adventures in Orbit slot by 888, where you’ll get to battle against asteroids to save the world. Enjoy double wilds and a Cosmic Voyage bonus game which is sure to send you back to Earth with more than just your spacesuit.

Or why not take a trip to the future with the 2050 Escape from Mars slot by Espresso Games? Go on an adventure with wilds, a free spins round and a bonus game with generous multipliers just itching to give you massive wins.

Make your way to Jupiter

IO online slot is guaranteed to give you hours of fun and entertainment, starting from the bet strategies. We love these as it gives you more control over your bets and winnings. There are also so many amazing features: Charges Wilds with four lives, Wild Forges with multipliers, laser beams, a unique bonus game and much more. All with an RTP of 96.00% and medium to high volatility.

The only thing left to do is play IO slot online today and try out these features for yourself!
