There is absolutely no way on earth that we could give you a complete list of all the variants in slots. Because of the extremely simple nature of the game, it is possible to add a new twist, spin or payline to just about any game and make it almost entirely new. On top of that, game developers are constantly designing new slots to bring to market, and competing with each other for market share. As a result, you can get anything from a game with three straight paylines, three reels and just a few simple symbols, to one with several reels – some of them split – tens of paylines, and multiple unique symbols, each with its own special feature. Some slots also have bonus side games like wheel spins.
Naturally, the variations don’t stop with the game’s structure. The themes are endless, covering adventure, wildlife, fairy tales, movies, sports, casino card games, music… there are even games around holiday themes. They have different, often mind-blowing, animation styles, music and sound effects, as well, making every game a new experience.
