Users like the best online slots to play of several types. There are slot machines with special symbols connected to the system of drawing the progressive jackpot. 

Types Of Online Slots

Users ask how to play popular slots online free, enjoying the game? They are available in modern casinos, where each paid analog comes with a demo version. You will find information about the history of this type of games on the page. It also describes the right status in different jurisdictions.  

In addition to listing the types of slots, users need to look for a reliable and safe place to play. The casino Cryptoreels which has been operating since September 2019 is suitable. Its site belongs to the Club World Group platform, where people have been playing for more than 20 years. The collection includes gambling games from world famous software developers. There are different types of slot machines, including those connected to the system of drawing of the progressive jackpot. 

Division by the Number of Reels 

The most common four options are three, five, seven and nine. The first option is the analogue of the old mechanical machines, the second is the most probable (used in both classics and modern video slots). The main categories include music, fruit, pirates, comics, jewels and animals. In addition to colorful graphics, a large number of bonus features are also provided. 

The third option is popular due to the large number of winning combinations. When playing slot machines with nine reels, each symbol spins independently of each other. Payouts are accrued if identical pictures are arranged vertically. In addition to bonus games, progressive jackpot draws can be held. In the latter case, the amount of the maximum winnings increases with each bet. 

Classic and Modern Slots  

When choosing the best online slots to play, it is worth considering their division into classic and modern. The former externally look like the models that were in the ground halls a few decades ago. In addition to images of fresh fruit, the paytable may include bells and sevens. The number of reels is three or five, payable combinations are most often stacked on a single line. They can have additional functions, which include:

  • re-spins;
  • free spins;
  • risk game with cards;
  • progressive jackpot.

As an example, we can take Sizzling Hot from the world-famous Austrian developer Novomatic. The structure has five reels, pictures are located under the scheme 5×3. There is a special symbol Scatter in the form of a five-pointed star, which is paid when it falls outside of the active paylines.  

Modern video slots have Wild, when falling out in the right position, the icon replaces the disadvantageous images. There are four more types of such special symbols, information about which is given in the table. 

Folded  Stretched vertically by several cells
Expanding  Takes up the entire reel ( with some game situations)
Giant  Expands horizontally and vertically into several positions (for example, 4×4)
Sticky   Stays on the playing field for the next few spins


Different types of bonus rounds are used, for example, with the choice of items. After clicking on a particular picture, the payout amount is revealed. The free or re-spins are given more often, with chances to hit winning combinations without additional bets. The story mini-games can be carried out on a separate screen in one or two stages. 

There are prize options that are activated when a certain number of extra points are collected. Another possibility is the transformation of symbols, when some pictures are changed into others. 

The popularity of modern slot machines is growing for other reasons that are not directly related to winning. Three-dimensional graphics and an introductory video to explain the essence of the storyline can be applied. The latter repeat themes of fairy tales, movies, comic books, dedicated to the traditions of different countries and nations, Christmas or New Year holidays. 

Classification by Type of Spinning Reels and Combinations 

There are slot machines with the Avalanche feature, for example, Gonzo’s Quest about the adventures of a Spanish conquistador in Latin America. They have no spinning reels, there is a drop of symbols from top to bottom. When making a winning combination, the icons within it disappear, new pictures replace them. With each cycle, the payout multiplier can grow (up to x10). The scale is sometimes filled to activate the cumulative bonus (with a continuous roll of prize combinations).

Other developers have a feature called Cascading Reels. It is in the slot machine Prissy Princess manufacturer Play’N GO. Before you start, you have to choose one of four mode:

  • proud dragon;
  • treasure chest;
  • dragon’s breath;
  • tournament.

Winnings are accrued on the same principle as in Gonzo’s Quest. The special Wild symbol on the reel can occupy three cells vertically. This increases the chances of winning. The bonus game is randomly launched, the participants will fight for the heart of the princess. An additional screen shows a tower, three knights and a dragon (users have to choose one). 

There are reels in the structure of regular machines, which are triggered by three methods at the beginning of the game:

  • manually;
  • automatically;
  • in turbo mode. 

The result of the spins depends on the random number generator. There is another type of mechanics – Megaways, which is known since 2016 thanks to the Big Time Gaming. It is provided in slots with a non-standard playing field, on which there are six reels differing in height. The number of schemes for counting winning combinations is more than 100.

With the cluster principle, identical symbols are in adjacent positions. They must touch each other vertically and horizontally. Examples include Aloha Cluster Pays, developed by the world famous company NetEnt. Payment is given when a chain of nine or more identical icons. The amount of reward depends on the number of pictures.   


To begin with, users can choose free games gambling slots for familiarization. In this case, it is possible without risk to get acquainted with the features of different types of slot machines, which are represented in the collection of the institution. This is  an appropriate option for the game with real bets chosen at your discretion.
