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.

The Book of Ninety-nine slot is similar to Book of Ra in many ways, including its expanding symbols and collection system. As with most online slots, the game revolves around the Book symbol. This symbol acts as both a scatter and wild symbol and can award a win if three or more appear. In addition, the bonus feature has a unique expanding symbol that can create winning combinations. Its payout is high compared to other online slots, and it is worth playing the game to see what it has to offer.
