Online Slot Reviews: Spotting the Best Slot Machines

Online slots are, without exaggeration, one of the most popular entertainments among gamblers. The reason for this is the lack of complex rules and combinations and the incredible variety of slot types, game themes and additional features. In addition, players worldwide prefer to spin virtual reels due to the considerable flexibility in bet sizes and preferences.

Try your luck in classic fruit slots, launch a 5-reel slot machine or enjoy modern slots with high-quality graphics – the choice is yours. Our online slot reviews are all about playing online slots and about the best providers of virtual slot games.

How Virtual Slots Work

At the heart of virtual slots is the principle of operation of all familiar slot machines in land-based casinos. The key difference is that the player presses the buttons on their devices’ screen and plays their favourite games without leaving home.

Like the prototypes of one-armed bandits in the best casinos in Las Vegas, virtual slots work based on an RNG or a random number generator. That is, the combination of each reel spin is determined randomly. Therefore, online slots are a classic example of games of chance, where nothing depends on the gambler’s skills.

Another difference between online slot machines and those in physical casinos is the frequency of winnings and betting limits. Online operators usually set lower betting limits. Firstly, this is due to the faster pace of the gaming process, which is almost twice the pace of playing slot machines in land-based casinos. Thus, by offering lower limits, gambling platforms encourage punters and try to compensate for higher risks.

As well, fans of running a virtual drum cannot participate in tournaments since it is more difficult to find such an event online.

Understanding RTP

The RTP or Return to Player is usually stated in the game description as a certain percentage. This indicator shows the theoretical return to the player of the funds spent on the game for a certain period. For example, let us say that the RTP of a certain game is 98%. This means that over time, the gambler could theoretically earn an average of C$0.98 for every C$1 spent on the game.

Available Types of Online Slot Machines

Modern slot games surprise with their diversity. Starting from 3- and 5-reel slots, ending with video slots with high-quality graphics, everyone can choose a slot machine to their liking. These are the most popular categories of virtual slots, so we decided to describe them in detail in our online slot reviews.

Video Slots

Video slots are like regular video games on your computer or any other device. In many ways, this type of slot is similar to classic machines with reels and multiple lines. One of the reasons why video slots have so many fans is the bonus rounds and good graphics.


3- and 5-reel Slots

If you had a chance to play in land-based establishments in the distant 1970s, you would have seen these same 3- and 5-reel machines. They got their name from the number of reels (hence the lines on the screens 3 and 5). These are the most popular slot machines among the visitors of virtual casinos.

The main difference between video slots and 3- and 5-reel slots is that the first type offers smaller winnings with less dynamic losses. At the same time, multi-reel slots offer punters bigger wins with frequent losses.
