Book of 99
When it comes to slot games, Book of 99 is one of the best. Not only does it have a 99% RTP, but it also has a unique expanding symbol mechanic that can deliver big wins. You can win up to 12,075 times your original bet when you land at least three or more Wild symbols. This game is also unique in its twist to trigger free spins. So, what makes it so great? Here are some of its main features:
It has ten paylines, which means that a combination of three matching symbols will create a win. The lower paying symbols are poker ranks, while the higher-paying ones are Greek mythology symbols. The higher-paying symbols also pay out on two-of-a-kind combinations, which helps boost the RTP. In addition to this, the Book symbol also triggers the free spins feature, which is where players can take advantage of a special expanding symbol.

Its payout is high compared to other online slots, and it is worth playing the game to see what it has to offer.
