Book of 99 - What you need to know
If you’re after a classic 5-reel, 3-row slot, then Book of 99 by Relax Gaming offers just that. With 10 active paylines, you need to land 3, 4, or 5 matching symbols or wilds from left to right on one of these paylines, starting from reel 1, to hit a win.
Book of 99 is one of those classic Greek-themed slots, like Thor’s Lightning, with an impressive design, filled with mythological characters such as the one-eyed Cyclops. The world is fitting to the theme with the addition of the gods. With the visuals and backing track, there is an aura to the slot that completes the game’s aesthetic design.
The reels are set against a night-time backdrop and are framed within elegant marble columns. As well as bejewelled playing cards, the reels are decked with higher-value symbols, including Lamia, Cyclops, Pythia, and Apollo.
However, it is the Book symbols you’ll want to look out for - which serve as both a wild, substituting for all standard pay symbols and also a scatter. If you manage to land three Book symbols on the same spin, it will trigger the Free Spins feature.

Bonus Rounds in Book of 99
There are two main features in Book of 99 - the Free Spins and the Collect Feature.
Free Spins Feature
To activate the Free Spins feature, you will need to collect 99 books, which will give you 10 free spins. Before the round starts, one of the standard symbols will be randomly selected to become a special expanding symbol throughout the feature.
After each free spin, the payouts will be calculated - and if the special symbol appears, it will expand to cover the whole reel. As well as the regular payline wins, the special expanding symbol can help to complete winning combinations.
However, what sets this feature apart is that the expanding symbol doesn't require symbols to be connected. For example, if you land expanding symbols on reels 1, 3, and 5 then it can create a winning combination during free spins. The maximum win you can get depends on which symbol is chosen as the special expanding symbol.
If you land another 3 or more Book symbols during the feature, you can retrigger the feature and get an additional 10 free spins - and there’s no limit to the number you can get!
