Come and visit the casino space station and go on a trip through space to mine immense amounts of invaluable minerals in ELK Studios’ Io online slot game! Named after Jupiter’s fourth largest moon, the Io slot game is quite a treat for fans of the space-theme in slot games. In Io, they bring back the Gravity mechanic they used in their Cygnus slot game and it is certainly a strong feature with the symbols tumbling randomly left or right. Aside from the unique mechanic, Io has bonus features such as special Wilds, a Laser feature, and a free drops bonus game! All of that plus up to 4096 ways to win which can expand up to 262,144 ways to win!

How to Play Io Online

Your bets in the Io slot game can range from 0.20 to 100 and you can choose your preferred bet from a list of given choices.
With the Gravity mechanic always on, with each spin 24 symbols fall into the game’s screen to create 6 columns and 4 rows with up to 4096 ways to win. This number of paylines expands to up to 262,144 ways to win with the Avalanche mechanic that activates whenever a win is hit and an extra row is added for a maximum of 8 rows.
Winnings and winning combinations are paid out according to the game’s paytable.

Io Symbols

All the symbols in the Io game are represented by round discs and the higher-paying symbols are golden discs with classic symbols such as a Lucky 7, Pink Diamond, 4-leaf-clover, and a star. The Lucky 7 is the highest paying out of all of these at 10x for 6 on a payline. Card royals represent the lower-paying symbols in the Io slot machine.

In addition to the special Wilds, there is a regular Wild symbol that can substitute for any regular symbol in the game and a winning combination of all wilds will pay as the highest value symbol.

Io Features

In addition to the awesome Gravity mechanic and Avalanche feature, the Io slot online also has bonus features such as special Wilds, a Laser feature, and a free drops bonus game! Learn more about these cool features below:

Charged Wild

This special Wild symbol starts with 4 lives and it can only lose a life when it contributes to a win. This Wild remains on the game’s screen throughout a full reaction sequence. It disappears when all 4 lives have been used up.

Wild Forge

The Wild Forge wild will fill an empty space below with a multiplier Wild. The value of the multiplier can increase every time the Wild Forge contributes to a win.

Laser Feature

When Laser symbols appear on the screen, they will shoot a beam of light, clearing all symbols in the direction of the laser. If two lasers cross each other’s paths, all symbols in their directions are turned into Wild symbols. The Laser symbols disappear when used.

Free Drops

Land 3 or more bonus symbols to activate the Free Drops bonus feature which can reward 7 free drops and is played with 8 rows. During this feature, Charged Wilds and Wild Forge symbols will be collected at the bottom and become sticky for the entire duration of the feature.
