Online slots are computerized versions of the traditional fruit machines you’ll find at most casinos. Featuring dazzling graphics and an array of themed games, they often have several paylines which will payout when a winning combination of symbols is hit. Players can also expect exciting bonus rounds and a range of extra features such as scatters and wild symbols.

The best slot online sites offer an amazing selection of top quality games, fantastic sign-up bonuses and fast loading times. They’re available on all devices from desktop PCs and laptops to tablets and mobile phones. Some of them even offer cashback on every spin! The amount you get depends on the game you play, but it’s a great way to save money while having fun at the same time.

Before you start playing an online slot, make sure to test the payout percentage of the machine. Do this by placing a few dollars on the machine and seeing how much you get back after a certain period of time. If you see that it’s not breaking even, then the machine may not be loose.

The backend of a slot online game is controlled by random number generator (RNG) software which selects a series of numbers and assigns them to the reels. Then, when you hit the spin button, the digital reels will rotate and stop randomly. If matching symbols appear on the paylines, you’ll win a sum of money based on your bet and the type of symbol you’re playing.
