Listing the Features of Io Slots

This game is for anyone who finds space science intriguing. It has several exciting features that you should use to win as severally as possible. This game has the following features:

  • Wilds. These are common icons in various slots. In this particular game, they are called charged wilds as they have four lives. Thus, after a winning combo occurs, one life will end, and three will remain.
  • Avalanche. This feature activates when you play Io Slot for free or play it for real money and create a winning combination. Without a winning combo, it does not become active. Each time winning images explode, new ones appear. This cycle enables new winning combinations to be born. It also causes the rows to increase until they are 8. Once they are 8, you can officially have up to 262,144 win lines for yourself. The rows will begin at 4 with 4096 pay lines and then rise to 5, 6,7, and 8 with 15,625, 46,656,117,649, and 262,144 pay lines, respectively. This feature can increase your payout chances.
  • Multiplier Wilds. These are accumulating multipliers. They get active whenever there are constant wins.
  • Wild Forge. There is a Wild Forge symbol that is made to activate this feature. It causes the multiplier values to increase in an IO slot demo and real money games.
  • Bonus game. In a bonus game, you will receive 7 free drops and expanded 8 rows. As with free spins found in most slot games, the drops can be triggered over and over.
  • Laser Symbols. Whenever common icons collect on a line pointed by the laser symbol, they will explode. There is one exception, though. If common symbols cross 2 laser icons, they will automatically become wilds. If this does not occur, the reel will be full of icons again.
