This game has a 96 percent RTP.

How to Play Io Slot Online

IO is a simple slot machine to play. Here is a quick look on how to play the Io slot.

  • Io has 6 columns and 4 rows of falling symbols, as well as 262 144 at the top.
  • The bet lines are paid from left to right, with the premise that only the highest per active payline is paid.
  • When the player presses the button, the game begins.
  • Winnings are paid out in either the player's currency or coins.
  • Io has two modes of play: normal and bonus with free drops.
  • In Normal mode, all symbols drop with four rows and 4096 ways to win
  • Except for the Charged Wilds, all symbols included in a winning combination are eliminated after the current symbol drop wins are collected.
  • The remaining symbols fall vertically, sliding to the left and then back to the right until they come to a halt.
  • The new outcome is paid out, and fresh symbols fall from the sky. As long as new combinations exist, the Avalanche cycle will continue.
  • As the number of rows increases, so does the number of methods to win
  • Except for the Laser, Wild Forge, Charged WIld, multiplier wild, and bonus symbols, wild symbols can be substituted with any other symbol.
  • The greatest payout is for a combination of all Wild symbols.
  • The Charged Wild has an additional four lives. When it comes to a win, it spends a life, and when it spends its fourth life, it becomes a regular Wild.
  • In Io, you must land three or more matching symbols on neighbouring reels to form winning combos. The 7 is the most generous symbol in the game, paying out 5x for 7-of-a-kind combinations.

Io Game Features


Each time Charged WIlds contributes to a win, it loses one of its four additional lives. Once it has consumed all four lives, it becomes a standard wild symbol. Then there is the standard Wild symbol, which may replace any regular symbol and pays the most when it appears on an active payline.


When you make a winning combination, this function will activate. It does not become active unless there is a winning combination. Each time a winning image becomes viral, a new one pops up. This cycle allows for the creation of new winning combinations. It also causes the rows to grow until they reach a total of eight. You can have up to 262,144 win lines after they reach the age of eight. The first row will have 4096 pay lines, followed by rows 5, 6, 7, and 8, which will have 15,625, 46,656,117,649, and 262,144 pay lines, respectively. This feature can help you boost your chances of winning

Multiplier Wilds

These are multipliers that are accumulating. When there are consistent wins, they become more active.

Wild Forge

This feature is activated by using the Wild Forge symbol. In both the IO slot demo and real money games, it causes the multiplier numbers to grow.

Laser Symbol

When common icons form a line pointing in the direction of the laser sign, they will explode. However, there is one exception. When two common symbols cross two laser icons, they become wilds. If this does not happen, the reel will be filled with icons once more.

Free Spins

To activate the free spins round, you must land three bonus scatter symbols anywhere on the same spin, and the free spins are played on the maximum reel arrangement.
