Book of 99

How often do you really get the chance to spin a slot machine with a 99% RTP to offer? Not too often, but at Book of 99, that’s exactly what you can do! So why not take the chance and see what it can bring on this slightly spooky Book of slot.

Book of 99 slot review

It’s not exactly the most inviting characters that meet us on the reels in Relax Gaming’s new video slot Book of 99, but don’t let that put you off! The slot which will be available for play from May 4, 2021 has been equipped with several great features, many of them familiar to those who enjoy Book of slots. But then there is also the exciting dispute, a maximum RTP of 99% that makes Book of 99 stand out among the majority of competing slot machines.

The rest of the layout is fairly standard, with 5 reels, 3 rows and 10 paylines. Just like the RTP, the volatility is also at maximum, and is simply rated as 5/5 on a numerical scale. You can set the stakes from SEK 1 – 1,000 per spin according to how you prefer to play, with a possible maximum win of 12.075x the stake. In practice, this means a maximum profit of SEK 12,075,000, which is not bad at all for this type of slot machine.

As for the theme in Book of 99, it’s a bit of an odd mix they’ve chosen to run on. Namely, the background and game board look like they were taken somewhere from ancient Greece, while the high-value symbols on the reels represent a blissful mix of characters. Some of them look like ordinary women and men, but we also have one-eyed monsters and slightly terrifying ladies to contend with in the pursuit of the winnings. The low value symbols consist of various numbers and letters, while the special symbols represent books with 99 printed on them. Just as the name Book of 99 suggests.

Book of 99 bonus features

Just like a Book of slot should be, the bonus features in Book of 99 consist of a combined wild scatter symbol, free spins and expanding symbols. Why change a successful concept as well?

Combined wild scatter

The combined wild scatter is of course the book in the Book of 99. This is thus responsible for everything to do with bonus functions in the slot, from replacing regular symbols in winning combinations to triggering free spins.

Expanding symbols

These special symbols always come into play as soon as you trigger free spins on the slot. Before the free rounds start, one of the regular symbols is randomly selected and becomes expanding. This means that every time they land during the free spins they expand to cover the entire wheel they land on.

Free Spins

Next to the game board is a kind of map-like construction, which is actually a bonus meter. This is replenished by collecting wild symbols during your game rounds. When it is filled with a total of 99 wilds, the Book of 99 free spins is triggered. This gives you 10 free spins to spin, with the aforementioned expanding symbols active.

Book of 99 jackpot

No jackpot has been chosen to bet on in Book of 99. The maximum win in the slot is 12.075x the bet.

RTP and volatility

This is where Book of 99 really gets exciting! To stir things up a bit with all the Book of slots already on the market, Relax Gaming has chosen to throw in a 99% RTP into the game. It has then been combined with high volatility, all to maintain maximum excitement factor for the player.
