How the Scatter Symbols Work
For these symbols to work you need a certain number of them to appear on a single spin and you need to consult the Pay Table of the game you are playing to confirm how many. When the correct number appear they will activate a bonus feature which could offer Free Spins or even an interactive Bonus Game.
Most casino Slot Games do have scatter symbols, especially the 5-reel Slot Games that use Scatters to unlock bonus features. They can also be found on progressive Jackpot Slot Games and slots that offer bonus games. However, 3-reel Slot Games rarely have Scatters appear on their reels.
In order to know if the slot game you are playing has Scatter symbols, simply study the Pay Table associated with the game that you’re playing to learn whether it uses Scatters. The Pay Table will also tell you about Wilds and all the bonus features that the game contains including the important features of how the game actually works and what the winning combinations look like.
