Book of 99 review

Here’s what you’ll find once landing on the reels of this Book of slot: a huge RTP (99%), a very wide range of bets and some cool graphics.

The key to unlocking the most exciting moments in the game is the Book symbol. Acting as a Wild, it can substitute for other pay symbols and also trigger 10 free spins when 3 or more land on the reels. The special feature of the free spins round is that one of the pay symbols is randomly chosen to expand and cover an entire reel whenever it appears. This makes it possible to score wins in all directions, from any reel.

The ultimate goal is to fill the screen with these expanded symbols, especially if they are high-paying ones like Lamia, cyclops, or the main characters. Interestingly, this game stands out with its high RTP of 99%, setting it apart from others in the "book" category which tend to have lower numbers.

Whether you see this as a gimmick or a clever tactic to attract players, there's no denying that Book of 99 offers incredible value for money. It can be played with stakes ranging from 10 p/c for casual players up to $/€100 for high rollers, on any device.

Whichever way you spin it, this Greek myth-inspired slot provides plenty of action on its classic "book of" reel set over 5 reels and 10 fixed paylines.
