Book of 99 slot review (Relax Gaming)
Book of 99: The best paying slot of all time
Relax Gaming states on their website that they’re “rewriting history” with this slot.
Book of 99 has an RTP of 99%(!), and it’s indeed the best paying online slot of all times!
It’s (obviously) also the best-paying Relax Gaming slot, the best-paying Book of Ra slot, and it will take some time before someone will be top that!
Okay, Netent’s Mega Joker matches this generous RTP, but you can only benefit from it if you play the maximum bet and play the top game. Besides, the slot is ten years old and way too old and way too dull.
|SLOT: Book of 99 | SOFTWARE: RELAX GAMING
Number of paylines: 10 fixed paylines
RTP and variance: 99%
Maximum win: 5,000x
Betting range: $€0.10 – $€100
Bonus features: free spins
Casino Hipster verdict: HOT! The RTP speaks for itself, and the game is cool as well!
Book of 99 has much more to offer, besides the RTP, as it’s a joy to play. It’s not just an ordinary Book of Ra slot, as it has more options. I’ll tell you all about it below!
Gameplay and Features
It’s a 5×3 slot with 10 fixed paylines.
The slot has an Ancient Greek theme, and Midas (the God of war) is indeed the highest-paying symbol. A five-of-a-kind gets you a 500x win.
The other highs are two female Godesses and a one-eyed cyclops. The lows are the 10, J, Q, K and A.
The Book of 99 symbols are the Wilds. You can trigger the free spins in two different ways.
Way 1: Trigger the Free spins by landing three wilds
If you manage to land three or more wild symbols, you gain ten spins.
Way 2: Trigger the Free spins by collecting 99 wilds
Another way is by collecting 99 wild symbols during the base game. On the left-hand side, you see the collection meter, which is filled, by one step, for each wild symbol you spin.
The free spins – a special expanding symbol
Now, you see the typical Book of Ra features. A special expanding symbol is randomly selected.
The special symbol expands over an entire reel if you make a win. It helps that the symbols do not necessarily have to be adjacent, starting from the first reel.
For example, if you have three identical symbols on reels 1, 3 and 4, that’s just as well a winning combination.
Indeed, if the special symbol is the highest paying symbol (Midas), you can land 5000x with one spin if you manage to land this symbol on all the reels.
The payout percentage (RTP) of Book of 99 is 99%
The RTP of the main game is 99%, and I guess we’re informed by now, loud and clear!
The variance (volatility) of Book of 99 is high
Book of 99 is a medium to high variance slot, and the max win is just over 12000x. I expect to see more than enough wins exceeding 5.000x (a full screen of the best paying Midas symbols).
