In the context of video slots, scatter symbols are special icons that can trigger bonus features or free spins, regardless of their position on the reels. Unlike regular symbols, which need to align on a payline to create a winning combination, scatter symbols can appear anywhere on the screen to activate their effects. When players land a certain number of scatter symbols, they often unlock additional rewards, such as multipliers or extra gameplay opportunities. This feature adds excitement and increases the potential for larger payouts, making scatter symbols a popular element in many modern slot games.
