The pay table of a slot machine will tell you how much a winning combination of symbols can fetch you. Most slots have a candle light that indicates the denomination. If you match additional scatters during the free games, you’ll be awarded more free games. And the scatter symbol is actually one of the bonus symbols in a slot game.
