Book of 99

Book of 99 Online Slot Full Review

Relax Gaming rewrites history with its new online slot. Book of 99 is a 5 reel, 10 payline video slot where players battle among the gods in a 99% RTP slot, the first of its kind.

Collecting 99 books in the base game triggers 10 free spins, an additional way to the typical 3-symbol trigger. In this Greek odyssey warriors are welcome, one is chosen at random before entering the ancient empire in the Bonus Round. Once the mythical character is chosen, it gains expanding abilities in the free spins round, growing to fill the entire reel and catapulting the winning potential up to 5000x the bet.

The prizes may not be set in stone, but the potential is: when 3 or more book symbols land in the bonus round, 10 free spins are re-triggered, sending the winning potential soaring again.

Don’t judge a book by its cover, this “book of” game is unlike any other. Spin the reels, the Midas touch could be at your fingertips!

Features

Free spins

If 3 or more wild symbols are obtained, the free spins feature is triggered, awarding 10 spins. A special EXPANSION symbol is randomly selected. During free spins, the symbol can expand and, in addition to normal line wins, pay on all 10 lines according to the number of symbols landed and the corresponding paytable value. Note that the special expanding symbol will pay on each line even if the symbols are not connected from left to right.

Collection

For each wild symbol landed during the main game, the collection counter will increase by 1 step. Free spins will be triggered when the collection meter is filled with 99 collected wild symbols. Free spins triggered by collecting will be played with a bet size corresponding to the average of the bet sizes used when collecting each wild.

Note: Book of 99 online slot will be launched on 05/04/2021 at the best online casinos Relax Gaming.
