Meet a slot with space topics called IO, which developed ELK Studio.

IO is the second slot machine, after Cygnus from the ELK Studios developers, which uses the mechanic called Gravity. This time we had the opportunity to go to space, and perhaps it is here that you can get prizes 5,000 times more than your bet.

Play for free in the gaming machine IO

IO slot begins with 6 drums, 4 rows and 4096 ways to win. Winning combinations are formed when 3, 4, 5 or 6 identical characters appear from left to right on adjacent drums, starting from the first. Thanks to the mechanics of Avalanche, each win will add more series and lines, which ultimate will lead you to 8 rows and 262 144 methods for their formation.

Unlike most slots, the columns are not at the same level. Therefore, when the characters slide down, they may fall to the left or right depending on the strength of gravity. In addition to gravity, forcing the symbols randomly fall, you get a lot of functions that will accompany you on travel outside the land.

Bonus features of the IO slot

Avalanche Feature – enters the game after each win, with the result that you will see that these characters explode, freeing the place for others. Then a new range is added to the playing field and the number of ways to form a win increases.

  • 4 rows – 4096 ways
  • 5 rows – 15,625 ways
  • 6 rows – 46,656 ways
  • 7 rows – 117,649 ways
  • 8 rows – 262 144 methods

Charged Wilds Feature – Vilde symbol has four lives, that is, when he participates in creating a winnings you lose one life at the same time, Wilde stays on the playing field. When WILD symbol took part in four combinations it is removed from the game field.

Wild Forge – Fills the space at the bottom of the wild factor. Each time Wild Forge is used, the multiplier value increases. When it reaches the lower row of Wild Forge turns into Wild with a multiplier.

Laser Feature – Pay attention to the laser characters that appear on the drums that destroy themselves and any ordinary characters on their way, allowing new slip into empty spaces. When the rays are crossed from two lasers characters along the rays to the point of intersection become wild.

Bonus Game Feature – is the main feature of the IO slot. It is activated when you get 3 bonus symbols on the game field. Then you will be provided with 7 free spins with 8 rows and 262 144 ways to win. Any characters of Charged Wilds or Wild Forge remain sticky at the bottom of the mesh throughout the rotations.

Summing up, I want to say that IO is a good slot with interesting features that will be an excellent addition to the ELK Studio Portfolio.
