IO Online Slot Machine – Free Play & Review

The idea is that you’re in a space casino, and you’re playing this Gravity based game. You sit back and you watch the space beyond, and a planet in whose orbit you’re in, while on the reels the gravity-influenced symbols show four Royals and classic icons (clovers, lucky 7s, diamonds, stars, logos).

Developer

ELK Studios has a couple of very popular slot machines already, and there is also one more Gravity style game offered by them, called Cygnus. I would also suggest you try out their Gold series, with several adventure themed titles present in it, quite popular with players.

How To Play It

If it’s a game from ELK Studios, then the betting system is standard. It uses 100 coins, and the range of their total value goes from $0.20 to $100. This means that $1 coins are used in all their games, at the highest setting.

As for the way the game is played, that part’s a bit more special, without adding difficulty though. You’re using a system with 4096 ways to win on 6 reels. It has Gravity, a mechanic that we’re going to talk about below, but otherwise it behaves much like a regular slot with ways to win and cascading reels.

Special Features

Gravity is one of the innovations that ELK has brought to its slot machines, and IO is the second game to feature it. It allows symbols which are not part of winning combinations, to more naturally fall to the below positions, when the ones that got you paid are removed via an Avalanche style mechanic. Gravity influences the direction in which these symbols go down.

As the Avalanche that follows also adds one more row of symbols, the game area expands, and eventually you can get to 8 rows of symbols. At that point, you would have 262,144 ways to win to form combinations on.

There is a regular wild present, and it can be used to form new combinations, just as expected.

Charged Wilds comes with a number of lives, 4 of them, which will allow it to stay around even after it is included in a win.

Wild Forge is the other one, and its appearance can bring you a wild with a multiplier in an empty space that’s below it. Get this Wild Forge to reach the bottom row, to get it turned into a multiplier wild.

Laser is the name of a bonus symbol which can show up on the reels, and then it will activate a laser beam. It burns away symbols in its path, and there will be empty positions in which symbols from the top can fall. If two laser beams intersect, then you get a wild in the middle position.

Via the usual 3 to 6 Bonus symbols, the game can trigger 7 to 15 free drops (or free spins). The advantage for it is that you get to play it with 6×8 reels and the full 262,144 ways to win active. The special wilds are going to be turned into sticky symbols on the bottom row.

Maximum Payouts

It’s a game with good potential, as rewards of up to 5,000x the stake are a possibility, however unlikely. I’m saying unlikely, because the slot has high volatility, but I’m also glad to report that the RTP is set to 96%, so it’s not unfair for a slot machine.

Summary

ELK Studios hasn’t exactly revolutionized the slot machine with their Gravity mechanic, but it’s an interesting option anyway, which you’re not going to find in its competitors. Big payouts, high volatility, something unique to play with, these are ingredients that should make this slot enjoyable for veterans of the casinos.
