How Power Balls works
In play, the thing to watch for is tumbling reels, so a single spin can pay more than once. Power Balls runs 6 reels with fixed paylines. Stakes in the real-money version run from 0.01 to 1 per spin; the demo uses virtual credits instead. Playing the demo first is the cheapest way to find out whether a game's pace and feature frequency suit you.
