The era of fruity online slots with boring bonus rounds is long gone and now you can find a wide selection of high quality titles. Many are based on popular TV shows, films or other pop culture phenomena and feature themes that can appeal to all manner of gamblers. The best online slots also have a wide range of options and features that offer more ways to win, ensuring that the games remain exciting even after hundreds of spins.

The external mechanics of a slot machine are fairly simple; players deposit money, select their paylines and hit the spin button. However, the internal software of an online slot is a lot more complex. The random number generator (RNG) creates a new sequence of numbers every millisecond, and this determines which symbols display on the reels at the end of a spin. Independent agencies regularly test the RNG software to ensure that it is truly randomized and cannot be tampered with by players or casinos.

In addition to the RNG, online slots also have built in mechanisms that prevent cheating. The most important of these is that a player’s real money winnings can only be transferred to their account if they use a reputable online casino. Licensed online casinos will be subject to regular inspections by independent bodies to ensure that they comply with all gambling laws.

There are a huge variety of online slots available, ranging from Megaways titles to 3-D and branded games. Some of the most popular include Starburst, Gonzo’s Quest, Cleopatra, Rich Wilde and the Book of Dead, Rage to Riches and 88 Fortunes Megaways.
