Exploring the Casino Space Station

Start on a journey through the solar system by playing this space-themed slot machine. IO online slot transports you to Jupiter and provides more than just an average win. You’ll witness the planet in the background from your spaceship adorned with vibrant symbols.

The highest-paying symbol is the 7, offering a win of up to 1,000x your stake. Following that are a diamond, a clover, and a star. The lower-paying symbols on the IO slot machine include A, K, Q, and J symbols, respectively.

You’ll also come across a W, symbolizing the wild, and a planet with BONUS inscribed on it.

Aim for the Stars

Prepare for launch when you place your initial bet on the IO online slot. Choose between bets ranging from 0.20 to 100.00. Winning paylines run from left to right, and in the event of multiple wins during a single spin, only the highest one will be paid.

We have compiled payouts based on a 100.00 coin bet below. Keep in mind that the wins on the IO slot machine vary depending on the bet size. The larger your stake, the bigger your rewards. You can find the figures corresponding to your chosen bet in the game’s paytable.

Your payouts may vary if you opt for a Bet Strategy. These can be found by clicking on the coin symbol on the left side of the screen. Here are the fundamental strategies:

• Optimizer: your bet level adjusts automatically based on your selected percentage
• Leveller: your bet increases after five consecutive losses and resets after a win
• Booster: raises your bet by one level following a loss, up to a maximum of four times
• Jumper: raises your bet by one level after a win, up to a maximum of four times

The IO slot machine features an RTP of 96.00% and medium to high volatility, paving the way for significant wins!

Power up your Wilds

Bet strategies are not the only fascinating aspect the IO online slot brings to the table. In addition to your regular wild symbols that substitute for any other symbol, you’ll encounter lasers, charged wilds, wild forges, a gravitational bonus game, and more.

When you begin playing the IO slot machine, you will start with four rows. The Avalanche feature is triggered when you achieve a win. All winning symbols blast away, creating space for the remaining symbols (excluding the Charged Wilds) to drop into the vacant spaces. New symbols and a new row are rewarded with each win, up to a maximum of eight rows.

The Charged Wilds possess an electric current around them, functioning like a regular wild but with four lives. Each win diminishes its life count.

On the other hand, the Wild Forge fills the space beneath it with a multiplier wild. Upon each use, the multiplier value ascends, eventually transforming into a standard multiplier wild at the bottom of the IO online slot grid.

A laser beam will also make an appearance while you spin. Observe the laser as it shoots and removes itself, along with the symbols it contacts, from the grid. If two lasers appear opposite each other, the symbols in their paths will convert into wild symbols.

And let’s not overlook the IO slot machine’s Bonus Game. To access this round, you need three or more bonus scatter symbols, with the potential for retriggering within the game. Played with eight rows, this round awards free drops, Charged Wilds, and Wild Forges at the grid’s base, offering up to a 500,000 win!
