From fully mechanical machines with one handle, joker123 apk machines have evolved into modern machines, which take up the most space in the casino and are the most popular casino games, enjoyed by millions of casino players around the world. Stay with us, because below we will introduce you to the technology, based on which slot machines work.

About slot machines in general

Slot machines are popular slot games, consisting of 3 to 5 columns, with different symbols, many themes, and with different names. Deposit slot games use cash, coins, and chips.

The first slot machines were mechanical with rotating gears around a central shaft, and as such, they broke down very often. The lever would be pulled and the reels would spin. The reels were supported by notched discs, which when aligned triggered a payout. Replacing the discs with different notches, and rearranging the symbols on the reels led to certain twists and changes in the probability of the game.

 In the middle of the 20th century, the first electromagnetic slot machine was made, where gears were replaced by motors and electromagnets. The lever was replaced by buttons, which was another step toward an automated system.

The lineup slot in hockey indicates the player’s position on the ice, such as center, winger, or defenseman.

The introduction of video slots combined computer technology with a slot machine, where the reels were replaced with a computer screen and logic boards. The new technology aimed to make the results of each spin random. The improvement in graphics has led to video slots incorporating various animations, which has resulted in increasing excitement and enjoyment in playing these games.

Online slot machines

The most popular games offered by a casino are certainly online slots. Video slots are expanding every day, so there are hundreds of programmed games on offer, which online casinos put on their websites. The demand for online slots is increasing every day, and today some studios purposefully produce dozens of new online slots.

Online slots technology

In this chapter, we will describe the technology of online slots, so that you can learn how online slot machines work and, as well, assure you that this is a very fair game.

  • RNG – The basis of online slot technology is the Random Number Generator software, which determines the outcome of each spin, and where the possibility of predicting what will happen next is disabled. This means that each spin is not part of a planned sequence, is not associated with a specific win, but is completely random. RNG is hard to hack, thus fair and honest play is fully guaranteed. The composition of the symbols changes from game to game, according to a mathematical formula, which determines the value of the win. The computer at the beginning of the game generates 100 random numbers, and millions of combinations are an integral part of this game. Each time the player presses a button, the RNG will generate a different combination of numbers. Based on the algorithm together with the software that generates the RNG, the outcome is determined and the random numbering program will give a result, which is different for each spin from the previous one.
  • Graphics is something that makes this game very impressive and exciting.
  • Animations bring this game to life and make it very popular. Thanks to advances in digital technology, online slots are animated, and the most modern slots have a design that allows them to be played perfectly on different screen sizes, from computers to mobile devices. This is a great advantage for gaming, as more and more casino players prefer to play on the go, from anywhere.
  • Sound effects create a more realistic game experience, make it more intense and provide the player with an incredible gaming experience.

Paylines and symbols

Some slots have fixed pay lines, unlike others where you can activate multiple pay lines. Each symbol has a different value and just guessing a combination of certain symbols can lead to payouts.

Who creates online slots?

One of the most popular companies that creates online slots is IGT, which was founded in 1981, and has created some of the most popular slots, including the popular titles Cleopatra, Star Trek, and Wheel of Fortune. Also, a very popular company, which excelled in creating popular online slots is Microgaming, which is behind many popular titles, such as Thunderstruck and Mega Moolah.

Renowned developers are behind the online slots, which assures players of a fair and honest game. Luck in this game is the most important factor because RNG software performs checks and tests to ensure transparency and safety in playing.

Licensed online casinos use the renowned RNG system, which is certified by the Global Association for Testing Technical Systems. Over time, online slots become more modern and popular, but regardless of that, the random number system is still used in any case.


Behind slot machines is technology, which has changed a lot in the last 100 years. From mechanical to digital, slots have retained their gameplay and appearance, but over time have become more accessible to casino players.
