Scatters or scatter is a term that describes a type of bonus symbol you can find in video slots and slot machine games.
In most modern-day video slots, apart from the basic symbols, you can also find wild and scatter symbols. While wild symbols always act as a substitute for other symbols, scatters are usually the ones that trigger bonus features, such as free spins or mini bonus games, for example. The most common way to trigger these is by landing three or more scatters at the same time. However, keep in mind that this can change from one slot to another, depending on the design.
In addition, scatter symbols usually pay both ways. In video slots, winning combinations are almost always calculated from left to right exclusively, making scatters one of the best symbols to land in a slot game.
