How Do Slot Machines Work?

By Geraldine

Many are drawn to slot machines by their exciting experience of pulling the handle and hearing coins jangling, but there’s much more going on behind-the-scenes when it comes to this form of gambling. There’s an incredible amount going on behind-the-scenes that helps turn one simple lever pull into an unpredictable outcome of play – this article will examine how slot machines work from their inner workings (reels) to what happens when someone hits paylines.

Originally, “slot machine” referred to a device that accepted coins in exchange for tokens (usually drinks or cigars) as an indirect form of gambling. Such machines were often installed at saloons to attract gamblers who might place bets against each other and potentially win prizes; early mechanical slots operated randomly with odds determined by symbol positions on reels.

Modern electronic slot machines use a computer program known as a Random Number Generator (RNG), to determine their odds. This program generates groups of numbers related to different symbols; when spun, each spin’s results depend on these random numbers – just as if dice, roulette wheels or decks of cards had been used instead of RNG.

At one time, weightings for each symbol on a reel were determined using par sheets; today they remain unknown so as to allow players to be surprised by their winnings without anyone knowing exactly what the odds of the game actually are.

Modern slot machines feature three or five physical reels or virtual representations thereof spinning on screen, or they may be represented through video game representations with symbols ranging from traditional bells and sevens to restaurants, alien creatures or gift boxes. Some video games also include bonus rounds that let players interact with their graphics to unlock prize money prizes.

All these features are intended to add fun and excitement for the player, while simultaneously increasing time spent gambling. But none of them impact overall odds or house edge; all that can impact probabilities of wins is random number generator (RNG) selection of symbols from possible outcomes; that explains why one machine can win one day but then fail the next, regardless of how often played.
