How Do Slot Machines Work: The Math Behind

by Damjan

At the midway mark, 2023 is still on course to beat 2022 as the year with the largest revenue in the history of the gaming business. With the first-half revenue of $29.16 billion, 2023 is already approximately 18 percent ahead of last year. And slot machines generate most of the gaming industry’s income. So, how do slot machines work? There are two types of slots: modern computer technology runs online slots, while older slot machines run on mechanical systems. This article reviews their build, fairness policy, and everything else, so read on.

Considering various factors, here are the best online slots casinos with popular slots games suitable for both beginners and pros:

Understanding Slot Machines

There’s a probability you’ll win every time you spin the reels. When you spin, the machine randomly selects a series of numbers. These numbers determine where the symbols land on the screen. The amount of the payout depends on the symbols that you end up landing on and the machine paytable. You receive a payout if the symbols line up in a winning combination.

The Technology of Slot Machines

The same principle applies whether you play a game on a modern slot machine or on an old-timer. The player pulls the lever or pushes a button that activates a series of reels, determining the outcome. The number of reels is typically three or five, each with a different number of symbols. These symbols range from a few dozen to hundreds, depending on the particular slot machine.

The Mechanism Behind Early Slot Machines

Conventional, mechanical slot machines use a series of gears and levers to operate. The coin detector registers when you insert coins to play slot games and unlocks the brake, allowing the handle to move. A metal shaft in the center supports the spinning reels, while a braking system stops the reels. Sensors communicate the reel positions to the payout system. Generally, physical slot machines have over 20 symbols per reel.

Newer Slot Machines

The video slots’ design resembles the technology of old machines, but only on the outside. Inside, they’re run by a central computer that uses a random number generator (RNG) program to determine the outcome of each spin. Computerized slot machines use step motors to turn the reels and stop them at a predetermined point.

Slot Machine Gaming: Ensuring Fairness

When it comes to ensuring slot machines’ fairness when you play, there’s always a chance for you to win the game. That’s because slots use a random number generator. Thus, each spin is independent of the last and doesn’t influence the outcome of the next.

Random Number Generator

Random number generators are an essential part of slot machines. Slots are programmed with a set of possible outcomes, and each time you pull the lever or hit the spin button, the random number generator chooses which outcome will occur. Random number generators help to ensure that every spin is fair and unpredictable.

Symbol Selection

An RNG picks a random number for each reel stop on a slot machine. When you hit the spin button or the lever, the game chooses the numbers (and symbols, accordingly) associated with each reel and combines them to create your result. If you’re lucky, the machine pays out your reward.

Odds of Slot Machine Games

The House Edge

Most casinos feature a house edge (also known as house advantage) of up to 10%, meaning that the casino expects a 10% gain from all wagers.

The Gain Probability for Players

The house edge is the statistical advantage that the casino has over the player. One of the ways that casinos ensure that they have an edge is by offering different payouts for different bets.

Payback Calculation

To determine the chances of winning a casino game, we must calculate the slot payback. For example, scoring a jackpot combination on a three-reel slot machine, if there are 128 reel stops, the likelihood of hitting the jackpot is 1 in 262,144.

Wrapping Up

Since the introduction of online gambling in 1994, the number of gamblers playing from the comfort of their homes has risen to 96%. Thus, playing on online slots prevails over playing on a classic slot machine. Still, that doesn’t take away from the brick-and-mortar casinos, as slot machines are designed to be addictive.

Casino slot machines work on algorithms, and each gambling venue has a house edge. Make sure never to wager more money than you’re willing to lose. While you may not be able to beat the system, you can still enjoy playing slot machines without risking too much money. Just remember to gamble responsibly and have fun!
