In 1985, Charles Fey invented and presented the famous slot machine considered as a predecessor of modern casino slots. As years passed, we can see considerable changes in almost all aspects of the casino slot machines. Today, gambling games are available not only in regular land-based casinos, but also in an online world. Due to the preferences of people to choose online establishments, the ground clubs lose their rates. Therefore, the developers try to include such features to the online casino slot machines to make them look like a real land-based casino. Mainly, the casino owners try to focus on the slot machine design and its software. 

Accordingly, the developers look for exciting and creative options to include getting high-quality results at the end. Furthermore, anyone who wants to get more information about a particular online casino can freely visit their official website. The first thing that the player sees is the appearance and the slot machine design. Thus, the developers should not overlook the importance of the attractiveness of the slot machine games.

A chance to get bonuses in an online casino

Have you ever wondered about the differences between regular land-based and online casinos? There exist several variations, but one of the obvious ones is about bonuses. Overall, the essence of gambling is based on real money bets. If in land-based clubs, the players buy chips at the cash desk, in online casinos, the users make deposits through online payment systems. However, modern slot machine design includes such a possibility that players can start their internet casino games without any investments.

Especially, catching a bonus opportunity helps when you already have a not outstanding balance. Did you lose your motivation to go further? Here come the bonuses! In general, there are two types of bonuses in online casinos: no deposit and deposit bonuses. The first category, which is no deposit bonus, has no connection with a deposit at all. It means that the money that you have in your account has no association with this bonus. Then, how do these no deposit bonuses work? 

Firstly, these bonuses are several types as well, which may include categories for newcomers and already existing customers. For instance, new players can get rewards for registering or confirming their email address/phone number. Then, there are some bonuses available for existing customers. The users can get them simply sharing the casino link with their friends. Apart from this, there are daily, weekly, monthly bonuses for regular players. Later, following some simple regulations, who lat can become a loyal player and get a VIP player status. With this status, the users can get more bonuses, including gifts for the birthday or other special days. In a word, encouraging bonuses included in a slot machine design attract more concerned players.

Variations in online slots

As you may know, with the existence of online casinos, the developers tried to copy the functionalities of regular land-based casinos. However, they also added several new options and characteristics to improve them. We can highlight two types of slot machines: classic and multi-line slots. Classic slots are the analog of “one-armed bandits,” and they have three reels with a single game line. To continue with multi-line slots, we can say that they are online slots with the playing field consisting of 5, 7, 9 reels.

Among them, 5-reel slots are the most popular ones at the moment because of a large number of paylines. Then, come 7-reel slots that have a playing field containing no more than ten paylines, and smaller symbols on the reels. The nine reel slots considered relatively new look like regular three-reel slots with three paylines. The difference is that the symbols rotate independently of each other, and the paylines have horizontal, vertical, and diagonal directions. 

Apart from this, there are some other slots like progressive and 3D slots. Progressive slots are not much different from their real alternatives. For instance, here, to hit the jackpot, you need to play at maximum bets. 3D slots are slot games with more sophisticated graphics and detailed rendering. Specifically, developers use 3D technologies during their development to allow you to feel a distinctive and dynamic atmosphere. Because of this, you can enhance the sense of reality during the gameplay. All the features, including demo mode, bonus opportunities, and simple interface, are related to these slots as well.


Nowadays, online casinos do their best to satisfy the preferences of the public, offering their customers different quality services. Mainly, the owners try to collaborate with the top-rated software developers to have incredible design of an overall website and existing games. Therefore, it is better for a slot machine design to consider some crucial points, including the first impression on the players. This moment is very valid because if a user gets a feeling of excitement after entering the casino and facing well-classified information appear on the main page, he will understand the overall atmosphere existing in the games.
