The slot starts with 6 reels and 4,096 ways to win. Each time a win is created, the number of ways to win increases. It uses a unique "Gravity" mechanic and after a win, all symbols move to the left side of the screen. You can bet from €0.20 to €100 per spin.

To start this space journey all you need is:

• Open Io at your chosen casino
• Find out the value of symbols
• Carefully read the rules of bonus features
• Choose a bet: from €0.20 to €100 per spin
• Set the reels in motion!

This slot machine comes with high volatility, which means that you will have to work hard to create a prize combination of premium symbols or activate a bonus feature. The advantage of this volatility is that you can get really big payouts! The theoretical return is 96% which is the industry average and this is a good thing as many slots come with RTP well below the industry average.

What could be better than being able to play wherever you are? Fortunately, ELK Studios is a provider that does everything for the convenience of its players, so all of their slot machines, including this one, are created using HTML5 technology. You can spin the reels of Io on any modern smartphone or tablet as it is perfectly compatible with mobile devices. The slot does not require any apps to be installed, so you can simply log into the casino site from your mobile device and launch it using your web browser.

This slot was created by ELK Studios, a young Swedish gambling provider that specializes in top-notch slots. The company has an amazing portfolio of unique products and operates on a “mobile-first” basis, that is, they use a development method that prioritizes the mobile version. Their products support 20 different languages as well as multiple currencies. Among their popular games are Zulu Gold, Book of Toro, and Fate of Fortune.

Wild Lives

There are a number of bonus features in this slot machine and the first one you will likely encounter in the base game is the Charged Wild. This Wild symbol has 4 lives and 1 life is used when it is included in the prize combination. Then it does not disappear but remains on the playing field with its remaining 3 lives. This will continue until the next spin or until all 4 lives are used up.

Wild Forge

There is also a Wild Forge feature. It fills the space below the Wild symbol and applies a multiplier to it. Each time a Wild symbol is included in the prize combination, the multiplier increases.

Laser

When 2 laser beams intersect, all symbols between them and the two symbols from which the lasers come out become Wild. If there is only 1 laser on the playing field, it will remove all symbols in its path.

Free Spins

Landing 3 Bonus symbols will instantly trigger the free spins feature with 7 free spins! During this bonus feature, you always play with the maximum number of ways to win (262,144). Charged Wilds and Wild Forges gather at the bottom of the playing field to help you land some really massive payouts.

The provider has created a Demo mode for this slot machine, which allows you to spin its reels making bets with "fun" coins, not real money. This mode is easily accessible to every player and you don't even need to create a casino account to use it. Play for free for as long as you want! If you have used all the provided amount of "fun" coins, just reload the page with the slot machine and continue to test the game for free.

The maximum payout in this slot machine is 5,000x the bet. This is a good max win potential for a high volatility game and you will be able to unleash it during the Free Spins feature that comes with the maximum number of ways to win, Charged Wilds and Wild Forges. Good luck!

Did you like Cygnus? Then you'll probably love Io too! There is little difference between these 2 slot machines, although it would be wrong to call it a clone. Of course, the theme is completely new, as is the backstory, but the gameplay bonuses and the math model are somewhat similar. That said, Io has enough tweaks and twists to make itself a unique experience while still satisfying fans of the previous game. This release is worth your attention and we expect that this will not be the last thing we see in the gravity series from ELK Studios!
