Book Of 99 Pokie Overview for NZ Players

Book Of 99 is a Relax Gaming pokie released in 2021. At first glance, this looks like just another game with an ancient Greece theme, with even the additional features not suggesting otherwise. However, Book Of 99 has been a popular choice for all types of casino players due to its incredibly high RTP that stands at 99%. Here are some key features of the game, one of the highest RTP pokies players can find at online casinos.

Reels, Rows, And Paylines

The entire “Greco” action in Book Of 99 takes place on a standard “Book Of” reel set that comprises 5 reels and 10 paylines.

RTP & Volatility

The Book Of 99 RTP is 99%, with the high volatility matching the high return percentage. A math model structured like this theoretically represents a high-risk and high-reward experience.

Maximum Win Potential

The maximum win in Book Of 99 pokie real money version is 5,000x the base bet, which can be achieved in the Free Spins round.

Expert-Vetted Relax Gaming Casinos to Play Book Of 99

Our experts have tested numerous Relax Gaming casinos where the Book Of 99 pokie is available. Refer to the table below to see their top picks.

Casino	Book Of 99 Wagering Contribution	Book Of 99 Bonus Play Eligibility
Hugo	100%	No
Win Rolla	100%	No
Lanista	100%	No
Dragonia	100%	No
Ivibet	100%	No

Book Of 99 Real Play Experience: The Reality Behind the 99% RTP

The most important feature of the Book Of 99 slot is that it is promoted with a 99% RTP. However, this should not be taken at face value, since the 1% house edge can mean better returns over a long cycle, but players should be prepared for very long dry spells with no wins at all. This is due to the game’s high volatility. As to be expected from such a game, during my testing phase, I had a streak of 42 consecutive non-winning spins. Do not mistake the 99% RTP for guaranteed and frequent wins. —Arlo F., Editor

Bonus Features in Book Of 99

Book Of 99 is one of the most exciting online casino games with a set of additional features. It includes a Wild symbol that replaces all other icons, except the special Expanding Symbols in the Free Spins Round. Additional features include the Free Spins and Collection.

Free Spins

Three or more Wilds will trigger the Free Spins round, which starts with 10 free spins. A special Expanding Symbol is selected in this round. Any symbol can expand and pay out on all 10 paylines, even if the symbols are not on adjacent reels. Players who land 3 or more Scatters while this feature is active can get an additional 10 free spins.

Collection

The Collection Meter increases 1 step for every Wild player who lands in the base game. Free Spins are triggered when the Meter is filled with 99 Wilds.

Understanding Book Of 99's Stake-Based Collection Meter

In Book Of 99, progress in the Collection Meter is directly linked to your specific bet size. If you change your wager, you will initiate a new meter for that new wager. However, it is important to use this function carefully. If you notice that your funds are running low, do not lower your bet size in an attempt to reset the Collection Meter, as doing so will completely hide the books you have already collected at your original stake size. Choose a sustainable wager amount per spin, and stick to it throughout the game.

Paytable in Book Of 99

Low-paying symbols in Book Of 99 include the A-10 Royals, while nicely crafted Greek heroes and villains represent the higher-paying symbols. Below is an overview of the game’s paytable.

Symbol	2	3	4	5
Q, J, 10	/	0.5x	2.5x	10x
A, K	/	0.5x	4x	15x
Female and one-eyed villains	0.5x	3x	10x	75x
Female hero	0.5x	4x	40x	200x
Male hero	1x	10x	100x	500x

Expert Tip

Why Some Casinos Exclude Book Of 99 from Bonus Play

Some online casinos exclude Book Of 99 from bonus wagering contributions due to its exceptionally high RTP of 99%. Compared to most online pokies, this means a much lower house edge for the online casino. Therefore, allowing bonus funds to be used when playing this pokie can increase the operator’s exposure to promotional losses, and make bonus abuse more probable. To manage this risk, online casinos either prohibit this pokie from bonus play entirely, or assign it a reduced contribution rate toward wagering requirements. If you want to play Book Of 99 with bonuses, make sure to review the casino’s terms and conditions to confirm whether the game is eligible, and how it contributes towards wagering.

Our Verdict: Is Book Of 99 Worth Playing?

Book Of 99 has a familiar theme, a standard bonus feature and a familiar gameplay, but its 99% RTP stands out from most online pokies in the industry. In theory, this can provide decent returns to players over the long term. However, players should be aware that such high RTP combined with high volatility means long dry spells with no substantial wins. Therefore, budget control and patience are essential if you want to try this game.
