Io Bonus Features

You’ll notice that there’s a lot to like about the Io online slot game when you load it up. Alongside the Elk Studios gravity mechanic, which can cause symbols to tumble randomly to the left or right, you also have the grid of 6 columns and 4 rows. These can increase with each avalanche, bringing up to 8 reels and 8 rows into play. Upon reaching the highest level, you will have an unimaginable 262,144 different ways to form wins. And that’s just the start of what makes Io such a compelling slot.

Wilds

When it comes to forming wins, the Io slot features 3 different wild symbols. The standard wild operates as expected, by substituting for all other symbols, except special ones. But, you’ll also benefit from the wild forge and the charged wild at different points in the game.

The charged wild in the Io slot game starts with four lives attached to it, and this remains on the game area throughout a full avalanche reaction sequence. Each time it forms a part of a win, it will lose a life. Once all four lives disappear, it disappears from the grid.

When wild forge appears on the grid, it will fill an empty space below it with a multiplier wild symbol. The value of that multiplier then increases whenever the wild forge is used. The multiplier is unlimited, and if the wild forge falls to the bottom of the grid, it transforms into a wild multiplier, too.

Laser Feature

While you’re exploring the surface of Io, you may want to utilise the game’s laser feature. It destroys any regular symbols with its beam. If two beams cross, then the symbols along these light beams become wild.

Free Spins

The slot’s bonus symbols are the ones that will trigger the free spins round, with 3 or more needed to activate the feature. You’ll initially receive 7 free spins, but if you spin 6 of the bonus symbols into view, you’ll get 15. The round can be re-triggered, and for the full duration of the free spins, the grid expands to its 8×8 size. Charged wilds and forge wilds will remain sticky throughout, too.

Io Jackpot

The maximum reward possible from playing the Io online slot game is a payout of 5,000x your bet. This isn’t either a fixed or a progressive jackpot and exists solely as the game’s largest reward.

RTP and Volatility

When playing this Elk Studios slot, beware of the game’s high volatility and the RTP rate of 96%. As a result of these two key stats, you may not receive super frequent wins, but the combinations that you do form throughout your play will theoretically provide quite large rewards.

Where to Play Io

You can fly to the moon and bring the treasure back when playing Io for real money at the top online casinos. But if you’re not sure if you can handle the lack of oxygen, take it for a test spin with some free spins and other casino bonuses instead. The friendly bunch at Videoslots and Pelaa are offering plenty of bonuses to their new players who want to sample their best online slots for some fun first.

Io on Mobile

Should you ever want to play Io on the go, this is possible using your Android or iOS device. Access the slot via your mobile, and you’ll experience a high-quality level of gameplay from wherever you are.

What does John have to say?

Space may be the final frontier, but in this game, you’re stopping off on the moon. Don’t worry though, with the free spins round, three different wild symbols and a laser feature, you’re bound to survive it all and build up a stash of treasure in the process.

Pros

  • Laser feature
  • 5,000x stake
  • 3 different wilds
  • Expanding grid size

Cons

  • Visuals could have been more impressive
