How to Play the Book of 99 Slot Machine

Like many Greek-themed games, the reels of the Book of 99 slot are framed by the sturdy columns of a temple. A book collection meter snakes up one side, leading you along the path to that magical 99 level. The symbols include jeweled playing card icons, and four character symbols, which pay the higher prizes when crossing any of the 10 paylines.

It’s a good-looking game, with some nice animations from winning symbols, and you can enjoy it on PCs, Android, iOS, and Windows mobiles at the best Relax Gaming casinos.

You won’t have any trouble getting started, as it’s designed for ease of use. Click the coin buttons to select a bet from a range of 0.10 to 100.00 for each spin at one of our recommended online casino sites. The double arrow button activates a fast-play mode, and the circular arrows start the reels spinning on their own.

Press the 3 small lines on the controls, and you get through to a paytable, where you see how much each symbol is worth, and how the various features can land you with big wins. The heroic character pays from 1x to 500x your total bet, depending on how many reels on a payline he lands across.

Free Spins & Other Book of 99 Slot Features

The mysterious book is a wild symbol which has the power to act as any other if it’s seen in the right place to complete a win. Each time it appears, whether it helps to form a win or not, the book collection meter rises by 1. Once you build up to 99 books, you gain automatic entry to a free spins bonus round.

It’s not the only path to the bonus games, as any 3 books appearing in the same spin will also launch the round. Before the free games begin, the book opens to reveal a random symbol that will expand on any reel it lands on throughout the feature. It doesn’t even have to be on adjacent reels to pay out, which make it much easier to grab prizes from whichever symbol the book selects. Any 3 books landing in a free spin will retrigger the round.
