Relax Gaming rewrites history with Book of 99, a first-of-its-kind 99RTP ‘Book of’ slot that pits players against the gods!

In the Base Game, collecting 99 books awards 10 free spins as an alternative to the standard 3-symbol trigger. Warriors are welcome in this Greek odyssey, and one will be chosen at random before venturing into the old empire in the Bonus Round. Once the mythological character is selected, it has to expand skills in the Free Spins round, allowing it to expand to occupy the entire reel and catapulting win possibilities up to 5000x one’s bet!


Book of 99 Slot Details

Wins aren’t guaranteed, but the possibility is – when three or more book symbols appear in the Bonus Round, 10 free spins are re-triggered, increasing the win possibilities even further.
