Book of 99

Matej94 Last Updated 2021-12-30

Whether you consider yourself a veteran or a beginner, you must have stumbled upon a “Book of” type of slot machine by now. It is common for such releases to contain a Special Expanding Symbol in the bonus round but, however, there’s much more to acknowledge in the Book of 99 online slot.

To tickle your imagination, for now, keep in mind that Relax Gaming casino software managed to deliver this online edition with a staggering RTP of 99%. Aside from that, you can still enjoy the “Book of” experience and win up to 5,000x the stake.

Theme and Symbols

The title is based on Greek Mythology, hence the theme of the game, and comes with a solid graphical representation. The reels appear to be pillars of a Temple while the background depicts a simple forest at night, atop Mount Olympus.

When it comes to the pay table, Book of 99 online slot contains symbols that depict 2 Gods, Cyclops, Medusa and low paying royals A, K, Q, J and 10. The Book is the Wild Symbol, substituting for all other icons.

This is also where this online one-armed bandit differs from the rest of “Book of” based releases where the Book would usually present both Wild and Scatter Icons.

Betting Options and Features

Book of 99 online slot is played across 5 reels, each 3 symbols high and 10 pay lines, offering a betting range of 0,10 - 100,00 credits per spin.

As noted earlier, the game’s best odds are 99% which is not something you see every day and speaking of high return to a player percentages, here’s our list of Best Paying Relax Gaming slots.

The highest win you can aim for lies at 5,000x the stake.

Aside from the Wild Symbol, the title comes with a round of Free Spins which can be triggered in not one but two ways, one of which being the regular case of landing 3 or more Book Wilds anywhere in view.

The second option is referred to as the Collection of 99 Book Symbols throughout the game. Once in, players are awarded with 10 Free Spins where one randomly chosen icon becomes the Special Expanding Symbol.

Keep in mind that the Special Expanding Symbol expands to cover the whole reel and in addition to any normal line wins, pay out on all 10 lines.

Wrapping Up

Frankly speaking, the provider did an excellent job and managed to keep up with our expectations as the Book of 99 online slot is anything but an ordinary “Book of” release. The best thing about it is of course the fact that it comes with a RTP of 99%.
