HOW PAYOUT RATE WORKS
To see how this works, let’s take a look at a very simple early slot machine, one with three reels and 10 symbols on each reel. The first two reels are identical. Each has five horseshoes, two spades, one diamond, one heart, and a bell. The third reel is different. It has two stars, two spades, three diamonds, one heart, and two bells.
