- Bonus Slots
In slot machines with bonus features, scatters usually initiate the bonus game. One scatter may be enough, in which case additional scatters make the bonus game even more beneficial, or the bonus game may require three scatters to begin at all.
- Multiplier Slots
Scatters may also be used as win multipliers; for example, one scatter multiplies your win by three, two catters multiply your win by six, and so on. However, in case you have no winning paylines, there are no winnings to multiply.
And they may simply give you significant winnings or free spins (in which case the amount of scatters usually dictates how many free spins you get).
Slots with scatters are known as "Scatter Pay Slots".
