Book Of 99
Book of 99 is a Relax Gaming video slot with a captivating Greek theme and arguably the best RTP we’ve seen in a slot for 2021! Moreover, the slot game has 5 reels, 3 rows, and 10 paylines.
The hit frequency of the Book of 99 slots is 29.83%, which is great for a “Book of” slot. It means that you’ll catch a winner on every 3-4 spins. You can also play for an incredible jackpot of 12,075x, though the volatility is high.
You can play Book of 99 as a mobile slot or a free slot at any of our top best EU casinos online!
To get the show on the road. Players can start making their bets at $0.10. In other words, at a cent per payline. High rollers can ignore that and go straight for the max bet of $100. Needless to say, the betting range will please any real money slots players.
Now for the big reveal. The theoretical RTP of Book of 99 is 99%! You’ve read that right, Relax Gaming tried to do something fancy with this one. Book of 99 stands well and truly above the rest of the field.
As a result, it’s a math model like no other and one that many players will fall in love with. Now, if we look at the house edge it’s 1%. For an online slot, it’s massive because it’s better than what many table and card games offer!
The theme will take you on a Greek odyssey with heroes and monsters. The low-paying symbols are only about card ranks. From Tens to Aces, but it picks up from there. You can look forward to seeing two heroes and two monsters.
For monsters, there’s the big Cyclops and the tricky Lamia. The visuals are nice to look at and they’ll draw you into the atmosphere. The team at onlinecasinos2.com congratulate the designers on a splendid job with Book of 99!
We can feel the disappointment from our Aussie players because the slot is sadly now available to them. Sorry mates. No need to bang your PC’s keyboard in frustration. A pokie we often play at the safest Australian casinos online is Lava Gold. Betsoft did a marvelous job with it from its RTP, bonuses, jackpot right down to the hit frequency.
The Book symbol combines with the Wild and Scatter. That means it subs for adjacent pay symbols and also triggers the Free Spins Feature.
Land 3 or more Book symbols and you’ll launch the Free Spins Feature. It’s what you expect from “Book of” slots, no big twists. Before your 10 free spins start; the game engine picks a random symbol as an Expanding symbol for free spins. This symbol can expand to cover an entire reel and also pays all ways, even when not adjacent. You can retrigger the Free Spins Feature as well, which is a neat bonus.
To get off the beaten path, Book of 99 also includes its own Wild Collection Feature. You collect Book symbols as you go and fill the meter that’s right next to the playing field. Once you collect 99 symbols, you’ll get to the end of the path and the meter will reset. Not before it gives you 10 free spins. They serve in the regular Free Spins Feature; so you’ll get Expanding symbols that are the slot’s heart and soul.
Book of 99 is an excellent Relax Gaming slot that we can recommend to every single player out there. Its main selling point is its huge 99% theoretical RTP. It’s so massive that it’s hard to argue with the slot’s potential. It translates to a low 1% house edge that beats even many casino classics!
The gameplay then builds on the traditional “Book of” formula. That means combined Wilds and Scatters alongside Free Spins with Expanding Symbols. To make things a bit more interesting, Book of 99 introduces the Wild Collection Feature.
For loyal players, that’s a big boost, as it guarantees free spins now and then. You might not get 3 Books on a spin. The interesting thing is you can accumulate 99 of them if you keep on playing.
The bottom line is that Relax Gaming went for something unique and they accomplished the goal. Book of 99 has one of the best math models out there and that counts for a lot. To get the best experience, give it a shot at one of our top European online casinos. You can even grab yourself a sweet bonus while you’re at it! Book of 99 is one of the best slots for clearing bonus wagering requirements.
