Game description

Book of 99

Book of 99 is a 10-payline online crypto game developed by Relax Gaming. Features included a bonus meter, a symbol collection feature, expanding symbols, and free spins. The journey home from the Trojan war was far from smooth sailing for Odysseus. It lasted 10 long years, and the brave warrior King encountered numerous challenges.

These included being captivated by the one-eyed Cyclops, as well as being tied to the mast to avoid the luring appeal of the dangerous Sirens. All the while, his ever-faithful queen and wife, Penelope, had her hands full fending off hundreds of suitors hungry for the throne.

Book of 99 is a Greek mythology-themed crypto game from Relax Gaming. The graphics are rendered in a unique comic book style that brings the legends of Greek myth to life in a new way. Like all Relax Gaming slots, there isn't anything to complain about in terms of its design. Book of 99 is a fantastic-looking slot that draws players in with its aesthetics.

The Book Collection feature is one thing that makes this crypto game stand out, and the book serves double duty as both the wild and the scatter symbol, per usual. As a wild, the book steps in for all regular pay symbols to help you form winning combos, and each book you land is also collected in the meter on the left-hand side.

The Wild Collection Meter is inspired by Homer (no, not the goofy Simpson character) and his famous Odyssey. Feel free to play this slot demo mode on our online crypto casino, as a visitor without signing up and now you can find it on our platform in crypto-game format.

This is one of the best online slots with a Greek mythology theme that I have ever played. Its RTP is an outstanding 99%, which is much higher than average.

not ordinary at all

Frankly speaking, the provider did an excellent job and managed to keep up with our expectations as the Book of 99 online slot is anything but an ordinary “Book of” release. The best thing about it is of course the fact that it comes with a RTP of 99%.

This one is tricky and I suspect 99% sounds better than it is. Im sure the collection feature has something to do with it. I couldn't triggered the free spins feature at all so I don't know what to say about that.

I’ve played the game for roughly 1000 spins now, and it seems to me that it is very unlikely that you reach free spins naturally by getting 3 books.
