Principles of Selection

Any rating is based on certain data obtained during a precise analysis of each subject under consideration. Thus, below, let’s see what criteria we considered when compiling the best online slots list.


The notion is the level of risk in a slot. It denotes quantitative and qualitative indicators of winnings in slots. In other words, volatility (dispersion) shows how often and how much players win in a particular slot. They distinguish three types of volatility: high, medium, and low.

High-volatility games are characterized by a high level of risks. The essence is that winning combinations drop out in such slots rarely, but the sum of won funds is significant.

Slots with medium volatility are the most widely used. They gained popularity among gamblers.

Low-volatility slots have a low level of risks. They frequently give out winnings combinations, but winnings are small.


RTP is the indicator that denotes the percentage of return to a player. This value shows the probability of winning in a slot machine. When considering the indicator, a player understands how much of his/her funds will return as a win. As a rule, the level of RTP on the best online slots sites is more than 90%. Reliable software providers always provide such information in the description of a slot.


Some games attract more gamblers, while others get less attention. This determines slot popularity. It is an important criterion due to the following reason: if more gamblers choose the slot, it means that it functions properly, and players are satisfied with the functionality of the game and its results.


This criterion determines how a gambler interacts with a slot, how he/she reacts to its interface and game reality, what emotions a game plot evokes.


A user creates the first impression of a new slot by judging its graphics. Graphics is the first thing a gambler sees when starting a new game and choosing a slot in the list of provided options. The first demonstration of the slot sets expectations. Paying attention to the graphics is necessary since it captures the imagination of players and makes them explore a new world.


Music creates the necessary mood. Pleasant music attracts a player, excites, and creates the illusion of being in a pleasant place during the gaming process. Thus, it is an important criterion for evaluating the best online slots for real money.
