IO Overview

Elk Studios are a company known for its innovative approach to online slots, and the company has once again delivered an exciting and fresh outing in the inter-galactic slot game, IO. IO is set in outer space, with the general theme of the game focusing on a group of explorers who have gone to a planet in order to discover some minerals.

This is not the most interesting thing about the game, though. The slot uses the gravity mechanic that Elk Studios also used in their popular Egyptian based slot, Cygnus. This is similar to an avalanche mechanic where symbols fall to replace ones that have been a part of a winning combination. Instead of just falling, though, the symbols can also fall left to right, helping to create even more winning combinations.

With such a unique mechanic, itā€™s no surprise that the game has huge winning potential. The game is made up of 6 columns, four rows, and a mouth-watering 4,096 ways to win.

Graphics & Theme

As weā€™ve already discussed, IO online slot is set deep in space. The gameā€™s visuals and themes reflect this, with the game having stylish and futuristic graphics. The gameā€™s symbols fall into a grid which is set in some sort of space ship, and the background of the reels is the control grid for this ship.

The game has plenty of bright and colourful animations as well, with the slot having a range of laser-based graphics that hit your symbols whenever you manage to score a winning combination. The soundtrack of the game also perfectly compliments this, with the game featuring various noises that are best described as lively and sci-fi inspired.

The symbols themselves all have simple designs. They are little stars that come in different colours, and the game also has the standard K-A symbols as well. Players can check the value of these at any time using the gameā€™s paytable.

IO Game Promotions

Aside from the obvious gravity mechanic, there are also several other special features that help IO stand aside as a great online slot game.

The site has many different features. The first one to mention is the charged wild symbol. This is a fairly standard wild symbol in that it substitutes for others to make a winning combination, but it stands out because unlike normal wild symbols, it has four lives. The symbol will down the grid after combinations and can be used four different times.

Next is the wild forge symbol. This has been used by Elk Studios in some of their other games as well. The wild forge will fill space below it on the grid with a multiplier wild symbol, the value of which increases every time the forge is part of a winning combination.

The laser feature is one of the ones that is potentially the most lucrative. The laser will destroy any standard symbols in its direction, and if two laser paths cross one another, they will turn all of the symbols into wilds, which could lead to some enormously big wins.

Finally, the game also features a bonus drops round. This is a standard free spins round where players are given a set amount of drops to see what they can win.

IO How to Play

IO slot may come jam-packed with a range of special features, but the gameplay itself is very simplistic and easy to get to grips with. To start the game, players need to select their stake using the +/- buttons that are located under the slots.

The game has a good betting range. Players can bet anything from $0.20 to $100 on each spin, providing them with the chance to get some big payouts. The game has high volatility and a 96% RTP.

IO on Mobile

If you want to try your luck on IO while you are out and about, then you are in luck. The mobile version of the game has been well-optimised to work on a range of different devices including both phones and tablets.

The game is supported on both Android and iOS operating systems and works well on numerous different browsers. Many online casinos will also have apps where you can play the game.

IO Conclusion

Pros
  • The Range Of Special Features
  • Fun Theme
  • Great Graphics
Cons
  • Highly Volatile
  • No Multiplier

Elk Studios are an innovative company, and IO is another enjoyable outing from the group. The gameā€™s design is excellent, and the gravity mechanic helps it stand out from the crowd. The range of special features that the game has other than this is also a huge selling point, and while the high volatility of the game may put some players off, there is still plenty of fun to be had with this one.
