Book of 99 Review
The journey home from the Trojan War was far from smooth sailing for Odysseus. It lasted 10 long years, and the brave warrior-king encountered numerous challenges. These included being captivated by the one-eyed Cyclops, as well as being tied to the mast to avoid the luring appeal of the dangerous Sirens. All the while, his ever-faithful queen and wife, Penelope, had her hands full fending off hundreds of suitors hungry for the throne.
It seems that Relax Gaming is hungry for another kind of throne, namely the ‘Book of’ throne. Their courtship to players comes in the form of an alluring 99 % theoretical returns, but the keyword here is ‘theoretical’. There’s no denying that this is an attractive and record-breaking stat, but the volatile nature of this game can still drain your bankroll to zero in the short run. Combined with the Book Collection feature, distinct visuals, and a compelling backstory, Book of 99 is undoubtedly up there as a very solid challenger.

Book of 99 Bonuses And Special Features
Book of 99 slot follows the familiar 'book of' slot formula, but introduces a unique twist to the bonus round triggering mechanism via the book collection system. Let’s check it all out!
Book Scatter/Wild Collection Meter
The Book Collection feature is one thing that makes this game stand out, and the book serves double duty as both the wild and the scatter symbol, per usual. As a wild, the book steps in for all regular pay symbols to help you form winning combos, and each book you land is also collected in the meter on the left-hand side.
The Wild Collection Meter is inspired by Homer (no, not the goofy Simpson character) and his famous Odyssey. Just like the classic dactylic hexameter poem, the meter depicts the Greek war hero and King of Ithaca, Odysseus, on his dangerous voyage home from the Trojan War (also depicted by Homer in his equally famous Iliad).
Anyway, history lesson aside, Odysseus' ship moves 1 step closer to home for each book wild you collect, and you need to collect - you guessed it - 99 wilds to fill the meter and reunite the brave King with his very patient wife, Penelope.
This awards you the bonus round, and it plays out exactly like if you trigger it by landing 3+ book scatters on the same spin.Book of 99 Free Spins
Landing more than 3 book symbols makes no difference in this game, as there is no scatter win involved. You trigger the Bonus Round with 10 free spins either way, and the Book opens up to a random page to reveal which symbol becomes the special expanding symbol during the bonus round.
If 1 of the 4 character symbols gets chosen, you need a minimum of 2 anywhere to trigger the expanding symbol feature. The low-value royal symbols require a minimum of 3 symbols to expand. All instances of the chosen symbol expand after the regular win calculation, and they don’t need to land adjacent to generate a win. You can retrigger the feature by landing 3+ scatters on the same free spin.

Strategy And Tips For Winning
To enhance your journey towards the untold riches of Ithaca, consider raising your stake when you feel the bonus round is just over the horizon. This may lead to grander rewards in the feature, akin to treasures hidden in Polyphemus' cave. But be wary not to let this strategy lead you astray, like Odysseus tempted by the sirens' call. It can prove costly if you become too consumed by the chase, forgetting the true goal of your journey.

Mega Joker - is the only other well-known slot out there featuring a 99 % RTP. Granted, you have to play with the highest possible stake to benefit from such insane returns, and you can win up to 2,000x your stake in the classic 3-reelers’ famous Supermeter Mode.
Book of Sun: Choice - is the highest RTP alternative to Book of 99, and this Booongo Book slot comes with theoretical returns of 97.74 % (at least for the Bonus Buy option). It also comes with a choice regarding the expanding symbol in the bonus round, and payouts up to 5,000x your stake.
Book of Dead - is still the king of Book slots, despite customizable RTP ranges and plenty of “improved” versions from countless competitors. The math model is as finely tuned as a trimmed Ferrari, and the expanding bonus round symbols can lead to payouts up to 5,000x your stake.
Review Summary And Verdict
Relax Gaming has understood that you need to go a bit “extreme” to have a shot at the ‘Book of’ throne. The popular genre is as overcrowded with competitors as Queen Penelope’s home is filled with power-hungry suitors in King Odysseus absent. Paying homage to Homer, and The Odyssey in particular, is a nice touch, and the Book Collection system fits the motif perfectly, while also keeping you motivated.
The big headliner is undoubtedly the record-breaking 99 % RTP. Few games are even close to such numbers, and even fewer slots. Just like the Sirens enticed Odysseus' men to their destruction with their seductive songs, so might this “magic number” have the same effect on unwary punters. In our experience however, the base game can be as dry as the bones in the one-eyed Cyclops’ cave, and the expanding symbol you get will pretty much make or break your bonus round.
