With their colourful reels, lifelike animations and engaging sound effects, slot machines are a form of casino magic. But understanding how they work can be tricky, particularly if you’re new to online gambling.

In online slots, the game outcome is determined by a random number generator (RNG), which generates different outcomes each time you spin the reels. This is how all slot games, regardless of the style or theme, are able to give players a chance to win every single spin.

Online slots can be simple and straightforward to play, or complex and immersive with features like Megaways, scatters, wilds and more. It all comes down to choosing the right online slot to suit your style and budget. The key is to find a site that offers generous welcome bonuses and has easy-to-use banking options, so you can get playing quickly.

Some online slot games also offer progressive jackpots, which pool the prize across thousands of players to make the maximum payouts much bigger. Unibet offers a great range of these games, including titles that pay tribute to Alice’s Adventures in Wonderland and more.

Another thing to consider when choosing a slot game is its RTP rate. This relates to the percentage of your total stake that will be returned to you as winnings. The higher the RTP rate, the better your chances of winning. You can check the RTP rate of each slot by reading its full rules and looking at its reviews on the internet.
