About Book of 99
Book of 99 – how about another “Book of”-slot but with a boosted 99% RTP and 12,000x stake max win?
Game supplier Relax Gaming has shaken things up this time by releasing a slot with the famous “Book of” theme with standard features and adding an unusually high RTP and a mouth-watering max win cap to the mix.
Book of 99 RTP
Online Casinos wouldn’t be too pleased if their players only played Book of 99. The reason is that the average and long-term RTP on this slot is an unusually high 99%.
This is currently the slot’s highest and only Return To Player version.
Still, the CasinoWizard keeps an eye on this and will update the information if Relax Gaming decides to release other RTP versions of this slot.
Remember that the slot has high variance, so you play with a more risky, high-reward approach.
Feel free to choose one of the trusted and popular high-payout casinos that offer Book of 99 to their players.
In most online casinos this slot can’t be used towards bonus wagering as the RTP setting is so high.
Gameplay and features
Book of 99 is played on a classic 5-reel, three-row game panel with 10 fixed pay lines. Bets start from $/€0.10 and go up to $/€100 per spin.
The Free Spins bonus round is familiar to “Book of” slots enthusiasts, while the Collect Books feature might be a new experience for some players.
- Free Spins: Landing 3 or more wild symbols on the reels during one spin triggers 10 Free Spins
A special expanding symbol is randomly selected before the Free Spins begin. The special expanding symbol will pay on each line even if the symbols are not connected from left to right.
- Collect Books: Every time a wild symbol lands on the base game’s reels, the collection meter will increase with 1 step.
10 Free Spins will be triggered when the collection meter is filled with 99 wild symbols.
The Free Spins will be played with a bet size corresponding to the average bet size used when collecting the 99 wilds.
What is the maximum win on Book of 99?
The best outcome when playing Book of 99 would be to win the 12,075x your bet per spin max win. With the max bet of $/€100, you would walk away with a sweet 1.2 million if you hit the capped max win.
Expectedly, the big wins can only be achieved during the Free Spins bonus round, which is won by landing three wild symbols or collecting the 99 books in the base game.
Once the Free Spins game is activated, you want to see one of the high-value symbols chosen as the expanding symbol and then rack those symbols all over the reels to achieve big wins.
In some cases, you could get lucky and land three more books during the Free Spins, which adds +10 spins to your bonus game, giving you more chances to win.
More 99% RTP slots
Book of 99 has an exceptionally high RTP of 99%, meaning that of all the money staked on Book of 99, an average of 99% will be given back to the players.
The higher the Return to Player, the more spins you get for your money and, therefore, the higher your chances of winning.
Finding other 99% RTP slots can be a difficult task, however, as there simply aren’t that many of them around:
- Ugga Bugga (Playtech): 99.07% RTP. This simple slot machine, which was released in 2006, offers held reels, wilds, and a 1,000x max win.
- Mega Joker (NetEnt): 99% RTP. Mega Joker is a classic NetEnt slot that offers a 99% RTP when playing the top set of reels. Be aware though, that the base game has a significantly lower RTP. You could argue that Mega Joker technically is NOT a 99% RTP slot as you always need to start in the low-paying base game before upgrading to the 99% payout secondary game.
- Some in-house crash games also have an RTP of 99% or higher. including Crash by Stake Originals and Crash by BC.Originals.
Other online slots with a slightly lower than 99% RTP include Jackpot 6000 (NetEnt) which has a 98.86% RTP, 1429 Uncharted Seas (Thunderkick) with a 98.50% RTP and Blood Suckers (NetEnt) with a 97.99% RTP.
The Wizards verdict: 4 out of 5 stars
While fans of the “Book of” slot genre have hundreds of slots to choose from (including Book of Dead from Play’n GO and Book of Shadows from Nolimit City), Book of 99 is the only one to feature a 99% Return to Player. On top of that, both the higher max win potential, and the collecting books feature add new elements to the genre.
Before you start playing, be aware that once the journey toward the 99 collected books has begun, it’s very tempting to keep going. The reason is that each collected book feels like a small win (not necessarily a win to your balance), and the Free Spins are in constant reach until the mission has been completed.
