Online slot machines are games that you play on a computer or mobile device. You insert money or, in the case of “ticket-in, ticket-out” machines, a paper ticket with a barcode into a slot, which activates the reels. If the symbols match up to a winning combination listed in the paytable, you receive credits based on your bet. Online slots are more advanced than their physical counterparts, offering a range of bonus features and colorful themes.

The best slot sites feature a wide variety of titles from many software providers, including industry giants and smaller boutique studios. They offer low, medium and high volatility games and have betting limits that suit all players. In addition, they offer exciting Megaways and instant win games, along with progressive jackpots.

A good online slot site will have a huge selection of video slots, and they’ll often let you test them out for free before you commit any money. These free trials will give you a feel for the game’s rules, payout rates and bonus features before you decide whether it’s worth your time and money.

When you’re ready to try out an online slot, click the button next to one of our recommended sites. This will open the site in a new tab and apply the best sign-up bonus code to your account. Follow the instructions to create your account, enter your details and agree to the terms. Once you’re approved, you can deposit and start playing real money.
