Guide to slots

Slots are the quintessential casino game, the easiest and quickest way to win (or lose) with online casinos as well as a nice, cosy way to ease into betting and gambling. It’s a game that anyone can play, without needing to study complex rules, hands, and scores. It’s all handled by the machine, so you just need to sit back, relax, and let the magic happen.

Since the very first slot machine, the Liberty Bell, was invented in 1895, game developers have strived to continuously innovate and create exciting games. Over the decades, they have brought all kinds of themes, designs, and styles to this popular casino attraction. Once the internet became more widely used, online casinos popped up all over the place, and this was truly the time for slots to shine. Today, slots make up the bulk of online casino games with tons of variations, features, and bonuses – no wonder many casinos offer nothing but slots.

Slots are all controlled by random number generators (RNG), which means there is no way to cheat. If you don’t believe us, check out our piece on slot strategies, which explains just how it all works.

There is 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 compete with each other for market share. The spectrum of online slots available starts with an easy game with three straight paylines, three reels, and just a few simple symbols, and ends with several reels – some of them split – thousands of paylines, and multiple unique symbols, each with its own special feature. Many 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, historic epics and much more – there are even games around holiday themes. They have different, often mind-blowing, animation styles, musical scores, and sound effects, making every game a new experience.
