Time to head to the frontiers of space where over the viewpoint of your casino spaceship you can see Jupiter as you head for your final destination: the moon of IO slot.
Elk Studios have really created something gorgeous here, with very tall reels that start with bouncing balls that are four in a row. On every win, those balls explode and the rest all bounce to settle below each other, and then an extra row of symbols are dropped down.
As the symbols pay left to right, it means you start with 4,096 ways to win and then increases. By row 7 this becomes a 117,649 ways to win, and then 8 rows (the maximum) pays out 262,144 ways to win.
In short, this is Elk Studios attempt at creating their own special megaways slot mechanics, giving you lots of little wins in the base game, and keeping you hooked as you watch the wonders of space from your cabin.
The thing about having a casino game that is tall is that you would think it would look better in portrait mode. But it really, really, doesn’t. This is by far nicer to play in landscape, which makes this far perfect as an iPad or Android tablet slot.
Because you are going to want to see each one of those little symbols disappear and these reels getting taller and taller with each avalanching win.
And that’s not all you can get in this IO slot game; you’ve got a normal wild, you have a wild forge that creates wilds with multipliers, you have charged wilds that stay sticky on screen for up to 4 avalanching spins and you have a laser symbol that destroys everything in its wake.
So much is happening, you may not realise that the wins aren’t earth-shattering, even when you get 6, 7, or 8 rows of symbols.
This Elk Studios slot is trying to give you the excitement of Megaways mechanics but in their own special way. Which means that most of the excitement is in the IO slot free spin bonus.
That’s because you play on 262,144 ways to win on every spin, increasing your chance of getting wins. But you also get more chances of getting multiplier wilds because the wild forge symbol doesn’t disappear per spin.
It will keep tumbling down, giving you multipliers, and hopefully, by the time it reaches the bottom, more wilds.
Does it always succeed? No. Is this IO slot a frustrating game? Absolutely. But you can win up to 5,000x your bet, and the action is plentiful. What more do you want from a new slot game online?

Avalanching Wins and Increasing Rows: You get a win by getting the same symbols from left to right. You start with 4 rows, and with each win, the symbols will explode, and not only will more tumble from above, but you'll get an extra row of symbols, adding to your possible ways to win.
The game goes back to 4 rows once no more wins are found.
The Wild: The W is the wild symbol and substitutes for any symbols except the special bonus symbols in this IO slot.
Charged Wild: The Charged Wild symbol has 4 extra lives. So it can stay on screen for up to 4 different avalanches rather than exploding on a win.
Multiplier Wild: these are generated by the wild forge. They act like a normal wild, except now they come with a random multiplier.
The Wild Forge: This is a blocked, but it carries a multiplier of 2 to start with, It fills any empty space below itself with a multiplier wild using the value it carried. This multiplier can be increased for every empty space directly below itself that it moves to, and for each wild multiplier it generates. If it falls to the bottom, it turns into a multiplier wild.
Laser symbol: This laser symbol will destroy all regular symbols along its beam. If two laser symbols intersect, all regular symbols along the beam, up to the intersection points, are turned into wild symbols.
Bonus and Scatters: Three bonus scatters anywhere in view trigger 7 free drops with 8 rows on every spin. During the bonus game, all charged wilds and wild forge symbols fall vertically, slide left and then right and remain for the next free drop.
Beautifully set in the vastness of space, this IO slot is gorgeous, but you really have to want to play on a vast slot that keeps expanding with every single win.
It takes a while to gain momentum, and not everyone will love it. In fact, we think this is really catering to the fans of the Megaways slots, with lots of little wins in the base game, but the really big wins only come in the free spins with that multiplier wild forge.
Don't expect the earth, but you might just be able to claim a little slice of IO thanks to that 5,000x your bet max win that gives you enough hope that you can get just half of that.
IO is a 4,096 ways to win slot game that has avalanching reels that expand by one row on each win, and multiple bonus wild features. During the free spins, you open up 262,144 ways to win and more wild multipliers.
