Slot games weren’t always as lucrative as they are today. In the early games, the payout was very small, which made professional gamblers pay more attention to table games. However, times have changed. You can now find online slot games with high RTP (Return to Player) — these games are considered to be the most profitable and offer the highest payout, giving players a chance to win big even if betting small. Let’s explore the most profitable online slots. 

Ugga Bugga

As the name suggests, Ugga Bugga is a slightly spooky and cartoonish-themed online slot game. It was the first slot game of its kind to be released with ten separate rows and three symbols on each row. The maximum win stands at 1000x . There are no extra bonus features available in this game, but the original setup gives the players more chances to win — and with a RTP of 99.07%, chances of winning seem pretty good.

Book of 99

Book of 99’s Greek odyssey theme will transport you to another era in which you’ll get familiar with various mythical characters and get a chance to win up to 5000x of your bet. This online slot game is all about collecting 99 books, which triggers Free Spins.
