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. Thanks to Avalanche mechanics, each win will add more rows and lines, which ultimately leads you to 8 rows and 262,144 ways to form them.

Unlike most slots, the columns are not at the same level, so when symbols slide down, they can fall left or right depending on gravity. In addition to gravity, which makes the symbols randomly fall, you get many functions that will accompany you on a journey outside the earth.
