Meet the space-themed slot called Io, developed by the ELK studio.
Io is the second slot machine, after Cygnus from developers ELK Studios, to use a mechanic called Gravity. This time we have the opportunity to go into space, and perhaps this is where you can get prizes of 5,000 times your stake.
The IO slot starts with 6 reels, 4 rows and 4096 ways to win. Winning combinations are formed when 3, 4, 5 or 6 identical symbols appear from left to right on adjacent reels, starting from the first one. Thanks to the Avalanche mechanic, each win will add more rows and lines, eventually leading you to 8 rows and 262,144 ways to form them.
Unlike most slots, the columns are not on the same level, so when the symbols slide down they can fall left or right depending on gravity. In addition to gravity causing symbols to fall randomly, you get a lot of features that will accompany you on your journey beyond the earth.
Avalanche feature - comes into play after every win, causing you to see these symbols explode to make room for others. Then a new row is added to the playing field and the number of ways to form a win increases.
Charged Wilds feature - a wild symbol has four lives, that is, when it participates in creating a win, you lose one life while the wild remains on the playing field. When the wild symbol has taken part in four combinations, it is removed from the playing field.
Wild Forge - fills the space below with a wild multiplier. Each time a Wild Forge is used, the multiplier value increases. When it reaches the bottom row, Wild Forge turns into wild with a multiplier.
Laser feature - Look out for laser symbols appearing on the reels, destroying themselves and any regular symbols in their path, allowing new ones to slip into empty spaces. When beams from two lasers intersect, the symbols along the beams 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 playing field. You will then be awarded 7 free spins with 8 rows and 262,144 ways to win. Any Charged Wilds or Wild Forge symbols remain sticky at the bottom of the grid throughout the spins.
Summing up, I would like to say that io is a good slot with interesting features, which will be a great addition to the portfolio of ELK games.
