In this article, we propose to understand how slot machines and real cash 3 patti work, the types of slots and their characteristics, and what developers were able to offer players the most original and exciting entertainment.

History of slot machines: how did the first one-armed bandits

It is believed that the prototype slot machine was developed by English inventor Charles Faye and introduced back in 1887. Among the progenitors of slot machines is also known product of the company Sittman and Pit, which introduced the virtual machine in 1891. The device consisted of five reels and 50 cards, as the game was based on the rules of poker.

Only in 1905, in America, there was the legendary Liberty Bell: a mechanism consisting of three drums with five symbols. The device worked on nickels with a face value of 5 cents, and the maximum win reached 50 cents.

The first gaming machines were exclusively mechanical and did not contain digital or software components. The player only had to throw a coin, pull the handle and activate the mechanism. After this, they began to move the combined shafts and gears, which issued a particular combination of images.

As for the first video slot, the first digital game was developed by the Fortune Coin Company in Las Vegas. It happened in 1976. It was not until 1994 that the world saw the first online slot: a game with three reels and one line to make combinations.

Within a few years, the developers entered into desperate competition for the players’ attention. With this in the market appeared virtual slot machines for 3, 5, 25, tens, and even thousands of lines for payouts, with reels of different formats and all sorts of additional features. Over time, video slot machines with three-dimensional graphics, animated intros, and intricate plots came into play.

Types of slots

All the slots have a crucial feature: the basis of the game of chance are rotating drums, which fall into several types of pictures. The player’s main task is to start spinning reels and wait until the same images do not add up to a winning sequence.

There are several basic types of slots, which differ not by the basic principle of operation, but by additional criteria and characteristics. Consider them in detail.

Classic slot machines

It is a primary type of slot machine, which features the most simple game rules. However, these slots have a few additional features and options, similar to the first slot machines.

Often, classic machines consist of a standard playing field of three drums with three cells each, located from one to five paylines. In rare cases, these slots contain an additional feature or symbol with unique characteristics.

A striking example of the classic slot game is Monkey Money from the provider Booongo. The gameplay unfolds on three reels, each of which is only one cell, and, accordingly, there is only one payline—a set of symbols – as simple as the rules of the game.

Fruit slots

As you can tell from the name, fruit slots are slot machines in which the characters are bright ripe fruit. Often fruit machines are a subset of the classic, but not always. As the theme of fruit is prevalent among gambling fans, modern developers often produce similar machines with non-standard features, many paylines, and bonus games.

An excellent example of the fruit slot game is Ultra Hold and Spin from developers Pragmatic Play. It combines cherries, plums, strawberries, watermelons, and oranges on the reels with a non-standard Hold and Spin feature, which makes the gameplay as involved as possible.

Video Slots

A separate category of slots that feature animated inserts, intros, and losses according to the storyline. Video slots are based on modern graphics and progressive visual effects. Quality animation, intricate plot, and the presence of video clips make such games more like actual animated movies than traditional casino games.

Modern games in this category often have unusual bonus games and extra features. However, the basic principle remains the same: the screen rotates the drum with characters that, depending on its location, may bring the player reward.

A striking example of this category is the slot Gonzo’s Quest of NetEnt studio, which has become legendary. The plot centers on a colonial conquistador looking for ancient Aztec treasures in the dense jungles of South America. The classic story, colorful intro, unique system of falling characters, and bonus game make this slot one of the best representatives in its category.

3D slots

Slots with three-dimensional animation and modern visualization. These games have excellent 3D images, which, together with good sound quality, create a maximum immersion effect in the gameplay. In addition to the impressive visuals, three-dimensional slots are characterized by fast operation, thoughtful gameplay, and a comfortable gaming interface.

Often 3D slots have an unusual storyline, which is reflected in the gamble’s additional bonus games, unique options, and features. Playing such slots is no less interesting than computer games. Thus there is a high degree of excitement and involvement.

An excellent example of a 3D-slot game is Wild Guns from the developer Wazdan. Western-style slot machine creates an atmosphere of exciting adventures in the Wild West, offering many additional bonuses and features.

The best slot machine developers

Today, the gambling market has dozens and even hundreds of companies involved in developing online slots. Every day new slot machines appear in the industry. However, the competition in the industry is as high as possible, so only some new developments capture players’ attention.

The gambling market is a recognized leader, and slot machines enjoy unwavering popularity among players worldwide. They include such companies:

  • Microgaming. 
  • Endorphina. 
  • NetEnt. 
  • Yggdrasil Gaming. 
  • Playtech.
  • Novomatic. 
  • Quickspin. 

The list of the best producers of gambling software – the value is not constant. Companies compete with each other, presenting more attractive, original, and involving games. Therefore, young studios whose games will revolutionize the gambling market may soon be able to break into the top.


Slot machines are the most popular type of entertainment in both land-based and online casinos. Despite many developers, styles, and models of slots, they all work on the same principle and have a similar control system. Once you understand this system, every player can understand how even the newest and most unusual slot machines work, replenishing the vast catalog of the entertainment gambling industry every day.
