With the advent of online casinos, the developers not only transferred all the functions and characteristics of land-based slot machines to the online space, but also added a couple of new options to the list of slot game varieties.

List of slot game varieties

Classic slots are essentially a virtual analogue of the “one-armed bandit”. Also, this concept can be attributed to any offline or online slot machine with three reels and one payline. Unlike real 3-reel machines, classic online slots can vary in theme. Many developers have abandoned traditional symbols, replacing them with thematic ones. Also, 3-reel online slots may contain special symbols or bonus games and be included in the progressive jackpot network. Classic online slots often have one payline, although there are exceptions.

Multi-reel slots are models of online slot machines, the playing field of which consists of 5, 7, 9 reels. Slots with an even number of reels are much rarer.
5 reel slots are among the most popular at the moment. They are always themed with lots of paylines (50-100), bonus symbols and games, free spins and progressive jackpots.

7-reel slots are not so popular among players yet. There are no bonus symbols or games in them, although, in a sense, these models offer more realistic conditions for winning. The playing field contains no more than 10 paylines, and there are much fewer symbols on the reels. To pay out, you need to collect any three symbols on one line.

9-reel slots have appeared relatively recently and, in fact, look like regular slots with 3 reels and 3 paylines. Only the symbols in them rotate independently of each other, and the paylines are arranged in horizontal, vertical and diagonal directions. Also, 9-reel models can be included in the progressive jackpot system and are not without various bonuses.

Multi-line slots – already from the name it becomes clear that these models will have several paylines. The playing field in the first multi-line slots consisted of three reels and three pay lines: top, bottom and middle. Now it is no longer possible to somehow classify slots by paylines due to the huge number of different options. Only a regular online slot with 3 reels and 5 paylines can have from 9 to 50 paylines, which is already talking about 5×5 models.

Progressive slots are not much different from their real counterparts. In order to hit the jackpot, you need to play at the maximum stakes, only in progressive online slots the bet limits can be lower than in real gaming halls, and there is more choice of models.

3D slots are models with more complex graphics and detailed drawing. When developing them, 3D technologies are used, which allows you to create a special, dynamic atmosphere and enhances the sense of reality of what is happening. The first 3D slots were presented to users in the online space, but since 2013 they began to appear in real gambling halls. In addition to bright and spectacular graphics, these slot machines are not much different from ordinary video slots. So 3D models are more likely to be of interest to players who want to get not only a solid win, but aesthetic pleasure from the game. If you want to try 3D slots in action, then pay attention to Betsoft Gaming products – the clear leader among developers of 3D slots.

AWP (Amusemt with Prizes) – translated as “entertainment with prizes.” These machines came to online casinos from British bars, where they were very popular with visitors. The playing field in these devices was not covered with glass, so the players liked to cheat and hold the drum with their finger or push it so that the symbol was in an advantageous position. Resourceful developers skillfully used this feature of AWP machines in an online game: from time to time, a player can use additional options and “hold” or “push” the virtual reel. The AWP slot looks like a classic one-line slot machine. The advantage is that the player can get an additional game with various prizes. True, the value of such a prize is not as large as in video slots and is comparable to a small payout.

i-Slots is a branded series of 5-reel interactive slots, which is presented only in online casinos using Rival software. Matching certain symbols in the main i-Slots game launches an additional game with a parallel developing plot. As the player advances in the main game, the player progresses through the sub-game’s storyline. Winning in i-Slots depends not only on the results given by the RNG, but also on the skill of the player. In addition, the entire gameplay will be accompanied by small animated screensavers.

In general, the slot industry is developing very dynamically, and it is simply impossible to list all slot options in one article. In addition, the gaming assortment of sites sometimes includes very unusual models that can hardly be qualified. In any case, when choosing the next online slot, pay more attention to the mathematics and the paytable. It does not hurt to get acquainted with additional information, read reviews of specialists and user reviews, watch promo videos of the slot, which usually show the key moments of the game. After all, the cool design and newfangled “chips” of the slot machine should not distract you from the main goal – the chance for a big win.
