We’re sure that there’s no experienced punter out there who doesn’t know what the abbreviation ‘RTP’ stands for.

But, all of you who are making your first steps in the world of online video slots should know that the theoretical return to player (RTP) is one of the main components of every online slot and it represents a minimum percentage that’s returned as a winning over a certain period of time. 

This time, we’re looking at an online one-armed bandit whose main highlight is its amazingly high RTP. Book of 99 is a mythology-themed online release packed with Wilds, scatters, Symbol Collection, Free Spins, and Expanding Symbols. 

As far as the payout potential is concerned, all punters who decide to give it a spin should know that the top payout stands at 12075x the bet. 

Before we jump into a more detailed analysis, we should mention that it’s fully optimized and highly responsive, meaning that you’ll be able to enjoy one of the best reels in the industry even on your mobile devices.

Theme and Symbols

After the Trojan war ended, Odysseus (the king of Ithaca and the main character of Homer’s Odyssey) traveled for 10 years in search of his kingdom and this online video slot is based on events from that journey. 

At the bottom of the paytable, you’ll find 5 low-paying royal letters worth up to 15 coins for 5 of a kind, while 4 main characters from the poem are the premiums here - land 5 and you can win up to 500 coins. 

As expected, the book acts both as a Wild and a scatter here. 

Betting Options and Other Functions

Book of 99 comes with 5 reels, 3 rows, and 10 fixed paylines meaning that players won’t be able to change this number during their sessions. Also, in order to score, you’ll need to land at least 3 identical icons across a single line. 

The betting range starts at 0.1 coins and goes all the way up to 100 coins while the title’s maximum win is set at 12075x the bet. 

Finally, high volatility is paired with yet unseen odds - the theoretical return to player (RTP) is set at 99% which is far above the current average. 

Special Features

As is the case with the majority of Book of… online video slots, the book icon represents the most important symbol in the game as it acts both as a Wild and a scatter. First, it will replace all regular paying icons and help you form even more winning combinations. 

In order to trigger the Free Spins feature, you’ll need to fill the meter placed on the grid’s left. It’s important to note that you’ll need to collect 99 book symbols to fill it. 

Also, the round can be activated by landing 3 books anywhere on the reels and the game will award 10 spins free of charge. At the start of the feature, one symbol will be randomly selected. 

Verdict

And just when we lost hope that iGaming software developers would revolutionize the Book of ... genre in any way, Relax Gaming casino software did something really amazing.

They brought us an online video slot which, in addition to the most used gameplay mechanics, offers extremely high RTP and a unique way to activate the Free Spins round.
