How a Slot Machine Works
Winning lines
Most machines have multiple winning lines on the reels, so options are given for how many lines the player wants to bet. Each line is equal to one bet, so on a five-cent machine, betting on five lines would equate to betting 25 cents.
Credit meter
A credit meter keeps track of how much credit the player currently has as well as winnings when the reels are spun.
Credits are often used instead of showing actual cash amounts because, to the player, losing credits may not seem as negative as losing money.
Arm or button
Once the player has selected how many lines they want to bet, pulling the arm or pressing the bet button locks the settings, selects a random number, and spins the reels.
