The game has a lot to offer and we suggest you first try the demo version of the Io online slot. That way, you will get to know the gravity avalanche that the game uses. You will also see how all those wild symbols differ from each other and how they work.

ELK Studios offers 4 betting strategies and you have enough free credits to try all of them and see if you want to use anyone when you play for real money. The demo version is pretty much the same as the regular one, so it will be like playing for real.

When you are ready to play the game with real money, we recommend you to head over to our The Grand Ivy casino review and find out more about the brand. The rating of the place is very good, and you will find some of the well-known software providers there.

The casino offers more than 500 games, not only slots but also roulette, blackjack and live dealer tables. Their welcome offer is quite good, and when you decide to open an account, they will match your deposit and will also give you some wager-free spins.

Gravity Winnings in Io

Io slot has very beautiful graphics and the playful soundtrack is the perfect addition to the overall feeling of the Space theme. The grid consists of 6 reels and 4 rows and all symbols are round, so they are in a zig-zag position. The game has gravity mechanics with an Avalanche feature. This means that after every win, the winning symbols will be replaced with new ones and some of the existing ones will fall either left or right.

Also, after every win, an additional row will be added, up to a total of 8, and this increases the ways of winnings. The autoplay and quick spin options are also available. There are no paylines involved because you start with 4096 ways of winning, and they can increase to 262,144. Besides the Free Spins, there is no bonus round, but there is a special Laser feature together with 3 different Wilds. All those extras make the game even more appealing to the player.

Special Symbols and Some Payouts

As we mentioned earlier, all symbols are round and you will see regular Red 7, Star, Diamond and Flower together with the playing cards images J – A. There are three wild symbols, W is the regular one that substitutes for all symbols, except the special ones. Charged Wild and Wild Forge are the Wild features and we will explain about them later.

The highest paying symbol is the Red 7 and how much it will pay depends on your total bet. If you have a bet of 1 per spin, Red 7 will give you 10 for 6 matches. J – A are the low-value symbols. You also have a Bonus symbol which triggers the Free Spins.

Advantages:

• Free Spins
• 3 Wild Symbols
• Multiplier
• Interesting Features
• Gravity Cascading Symbols
• Very Captivating

Disadvantages:

• No Jackpot
• No Bonus Round

The slot has a good betting range. The minimum starts at 0.20 and the maximum is 100. It is a good fit for the high rollers and for those on a lower budget. There is no progressive jackpot, but the maximum win is 5000x your bet and this is quite generous.

You will also see 4 different betting strategies, which don’t reflect the outcome of the game. They give you the possibility either to raise your bet after a win or a loss, or to bet a set percentage of your remaining balance. If you want to try any of them, you have to set this before you start playing.

Free Drops, Wild Features and Laser Beams

In Io online slot, you have the Free Spins and few very interesting features. You need 3 Bonus symbols to trigger 7 free drops. You will play with 8 rows, not 4, as in the base game. Charged Wilds and Wild Forge symbols will be collected at the bottom in the Free Spins to give you more chances of winning. You can also retrigger 7 more free drops if you get another 3 Bonus symbols. Charged Wilds is also a W symbol, but it has 4 lives. It substitutes for any symbol and is losing a life if it makes part of a winning combination.

Wild Forge carries a multiplier beginning at 2x and also substitute for any symbol. It fills an empty space below itself, and every time that is part of a winning combination, it will move one space down and the multiplier will increase. The other interesting feature in the game is the Laser. If you hit two of those anywhere on the grid, the beams of the two Lasers will connect and all symbols along the line will turn into Wilds.

Io slot RTP is 96% and it has more of high volatility. The percentage is good and you will get those avalanche gravity mechanics pretty often. The Free Spins are a little hard to get to and they don’t hit very often. The game has a hit frequency of 24.6%, so statistically, every fourth spin should come with a payout.

You will get small winnings of the regular symbol combinations, but when those rows start to expand the winnings are getting bigger and bigger. Also, if you get a combination of only Wilds, the payout will be the same as the highest paying symbol.

Play Io on Mobile

If you want to try the game anywhere and to use your mobile, it is possible. ELK Studios are always taking care of the mobile users and all of their games are ready for a mobile play. You can use either a phone or a tablet. Any operating system will do the trick. On the mobile version, you get everything as expected.
