Sometimes referred to as a slot player's best friend, the scatter symbol is basically a key to unlocking various fun bonus features designed within a slot game. Unlike symbols that have to be lined up on a payline to win anything, the scatter just has to appear on the reels to open up free spins, mini-games, or other bonuses. Scatter symbols are typically one of the highest paying symbols in a slot game and are represented by a specific graphic that is unique to the theme of the particular slot title.
Usually, a certain number of scatter symbols must appear on a single spin to unlock a feature. These details are outlined on the game’s paytable. When the required number of scatter symbols pop up on a single spin, the game will launch into the promised feature. Oftentimes, this is free spins, but sometimes the scatter symbol is used to open up other interactive bonus games.

The scatter features are usually game-specific, meaning that they function a bit differently across the board, according to the slot you are playing. That being said though, many scatter icons are simply just scatter icons and may sometimes just payout on a winning combination. You will find this is true on simpler slot games that do not offer bonus events outside of wild and scatter payouts.
