Slots are one of the most popular casino games. Their popularity has increased by double since the game was digitised in the 1990s. The most popular online slots offer high RTP (Return to Player) percentages, which indicate the percentage of money that is paid out to players in exchange for the initial bet. These games also often offer free spins.

Players can play slots using mobile devices, desktops, or tablets. This allows them to play anytime they have free time. The variety of slot games available online is another reason why so many people are playing these games. The best online casinos have hundreds of different slots available for players to choose from. However, when choosing an online casino, players should keep a few things in mind.

Play’N Go is one of the best providers of online slots. They produce some of the most popular slot machines and regularly release the most exciting new titles. Thunderkick is another developer who is catching up with Microgaming. This company released its first online slots in 2012, and has continued to add more exciting games to its portfolio.

When choosing the best online casino, look for one that offers generous welcome bonuses. These bonuses are good for new players, and are often accompanied by exciting promotions for frequent players. You should also choose a casino that offers many different payment options, including Bitcoin. In addition to this, look for a wide selection of slot machines with the highest jackpots.
