If you’re just starting out, join us as we dive deeper into the realm of online slots and find out more about where to play the best online slots.  

What are Online Slots? 

Online slots are digital renditions of land-based slot machines with colourful graphics and a variety of game play mechanics. All across the board, you will find familiar sets of reels, a few buttons to adjust the settings and a prominent ‘Spin’ or ‘Play’ button. 

The best online casinos have a large offering of online slot games from game studios around the world, from classic fruit-themed slots to modern games with innovative bonus features and interactive game play.

The very first slot machine, “Liberty Bell”, was invented in 1895 by Charles Fey, a car mechanic from San Francisco. It was an instant success and quickly became a staple of every land-based casino. The first online slot machines were replicas of the original, relying heavily on the time-tested style, complete with the box-and-lever look and feel.

Technological advancement facilitated the move of traditional slot machines to the digital era when computerisation allowed for the addition of previously unheard of features, like Scatter symbols and Free Spins bonuses. 

Players could now play online and enjoy a much wider variety of games from the comfort of their homes, with varied betting options and exciting features. Today, developers and designers are constantly exploring new creative directions, steering modern online slots toward interactive, video game-like experiences. 

Many slots stick to a classic setup of 5x3, but you'll come across plenty of games that deviate from the standard. Symbol combinations are generated randomly on every single spin, and a winning combination constitutes a combo of identical symbols that land on one of the game's paylines. Each slot game comes with its own instructions and symbol payouts, which can be viewed through the game’s rules and paytable.
