Casino Hipster verdict: Hot!
Or, if you’re betting a maximum of one hundred, a more than cool half a million! Are you going to go into space and find that luck? WHO KNOWS!
You start with 6 reels with 4 rows of symbols. We say rows, but the symbols go up and down and sideways. But if you ignore that, you see that there are four rows.
The game is played according to the win all ways mechanism. As there are 6 reels with 4 rows, there are 4,096 ways to win. That can go all the way up to 262,144 ways to win if you get the maximum number of 8 symbols on all 6 reels (8x8x8x8x8x8=262,144).
In the game, you also have the Avalanche mechanism, where winning symbols disappear. But the nice thing here is that a full row of symbols will be added for the next re-spin. For example, if you get a few consecutive winning combos, you will notice that there are many more symbols in the “space,” leading to many more ways to win.
But there is more.
You have the Regular Wilds, which change in every symbol except the bonus symbols. Nothing special, but useful.
Then, there are the Charged Wilds, who have 4 “lives”. You use such a wild 4 times to make a winning combination because these wilds only lose a life if you spin a winning combo. If not, the lives are kept.
There are also the Wild Forges, which are wilds with a multiplier. Every time such a wild is part of a winning combo, the multiplier increases by +1. It can go up to x20. If you get a nice series of consecutive wins, it can become highly lucrative.
But we’re not there yet.
There is also a Laser Symbol. Do you have 2 of them, then all the symbols between these 2 Laser Symbols are converted into wilds. With the win all ways concept, these Laser Symbols can create a lot of fireworks. In terms of prizes, I mean!
Grab your 3 Bonus symbols and activate the seven free spins. Elk Studios calls these Free Drops by the way.
The big advantage of the Free Drops is that you start with a fully filled “space” of 6 reels with 8 symbols each. Yes, that implies that you get the maximum of 262,144 ways to win.
The payout percentage of IO is 96.0%. It is just about okay, but of course not spectacular.
Elk Studios gives a score of 8 out of 10 for the volatility of io. This means that the variance is medium to high.
Most major top prizes will be around 500x to 1,000x the bet. Chances of winning anything more substantial will be very, but very small, but not impossible.
Other Elk Studios slots with similar volatility are Hidden, Wild Toro, Cygnus or Ice Wolf.
Players who appreciate a beautiful and original slot will not skip this slot. In one word: stunning! You have to dare to take some risks because this slot is quite volatile.
It is better to stay away from this slot if you suffer from dizziness or get over-excited easily.
