How Exactly do Slot Machines work?

Published 19/10/2020

Did you know slot machines require zero gambling knowledge? This makes them one of the most popular casino games; all it takes is a very small bet.

It’s no secret that technology has changed dramatically in recent years, yet the idea behind the slot machine is the same; reels spin and the mechanism stops randomly in positions which form a win or loss. If a winning combination is shown, the player is paid out dependant on the value of the symbols.

All slot machines used to work mechanically and were powered by a selection of levers, gears, sensors and a braking system. Now, these machines have mostly been replaced with video slots that are powered by microchips to control the motherboard, though the principle of the game is the same.

Hitting the spin button on newer machines makes the computer within the machine select numbers via the random number generator (RNG). This is fed to the computer, which then corresponds to symbols on the video slot reels. The computer will spin the reel to a corresponding symbol to form a winning, or losing combination.

Slot machines are completely random, though the odds can be set. Some machines will carry ‘Wilds’ while others may have a smaller number of bonus icons. Therefore, the chances of landing on a bonus icon or hitting the jackpot can vary radically.

Return to Player (RTP) percentages are always on the slot machine, normally displayed on pay tables. It’s important to understand that these are the theoretical long-term pay outs to players. For example, if a slot machine has an RTP of 95%, this means that over the long term, every £95/100 that is paid out by the machine, it will withhold £5. If a slot machine has a high RTP percentage, it doesn’t necessarily mean you will be a big winner quickly. Many people win big on low RTP games as well as high ones.
