A slot machine operates by using a random number generator (RNG) to randomly determine the outcome of each spin. The RNG generates a number for each reel of the slot machine, and the reels stop on the corresponding symbols. The combination of symbols that are displayed on the reels after a spin determines whether the player wins or loses.When a player inserts money or a ticket into the machine, the player is credited with the corresponding amount of credits. The player then chooses the amount they want to bet per spin and initiates the spin by pressing a button or pulling a lever.
