The online slot machines are so diverse and there are so many that you can play a different one every day. It's hard to assume that you will test all of them throughout your life. With this in mind, it's worth getting familiar with the symbols you can see in the games that you choose to play. Some of them are characterized by good graphics and animations but many are just simple images or names. However, they are important to know.
In terms of symbols, two types are the most popular in casino games. You will find them almost everywhere. The first category is fruits. These are cherries, plums, oranges, lemons, watermelons, sometimes also pineapples and others. The second category is all the symbols associated with cards, most often from number 9 up to the Ace.
Fruits and cards are the basic symbols and their value alone is not that high. However, they are almost always accompanied by other symbols. Usually, they are sevens, bars, bells, which are taken from the classic slots. On video slots, you can find unique characters assigned directly to the slot title. Some symbols are taken from TV series, movies, cartoons, rock bands. There are images created directly for the needs of games like guitars, weapons, sweets, fictional characters, vehicles. Many symbols are the reflections of the game name. So in the slot like Batman, you will see the image of Bruce Wayne or Joker, in Crazy Cats, there are several cat badges in different forms, sometimes dressed as real people.
