Relax Gaming Rewrites History With 99% RTP in Book of 99

Online gambling is a highly competitive industry, so developers need to be very creative when designing their slot games. To stand out among their rivals, you need to offer players something special like a fresh theme, innovative features, and game mechanics, or a massive winning potential.

Relax Gaming decided to take another approach. The company’s slot titled Book of 99 has a usual Ancient Greece theme, a standard potential, but its RTP, and an exciting collection system, will undoubtedly draw the attention of slot enthusiasts everywhere.

Ancient Greece Awaits

When it comes to its appearance, Book of 99 is a nice-looking game, especially once the bonus game is activated. The cartoonishly designed game symbols give it a recognisable Relax feel. Populating the reels are various heroes from Ancient Greece, together with villains from the country’s mythology. On top of it all, there’s a nice and a bit exotic soundtrack playing in the background, creating the perfect setting for an epic adventure.

Book of 99 is a highly volatile slot, played on a standard five-reel three-row layout, with ten paylines for players to benefit from. What makes this title stand out in the sea of similarly-themed releases and makes it more desirable to slot lovers is the RTP configuration we don’t see often. As the title of the game suggests, its Return to Player averages at 99%!

To start getting paid, you’ll need to match adjacent symbols on a payline, starting from the leftmost reel. On the reels, you’ll encounter a mixture of low-value symbols, such as the usual selection of playing cards and higher-paying icons, represented by cyclops, a child-eating monster called Lamia, as well as the main female and male characters. Landing five premium symbols can pay off, with prizes ranging from 75 to 500 times the triggering bet.

Book of 99 Features

If you’ve ever played a ‘book of’ style game, then you’ll know what to expect in terms of features. The central part of the slot is expanding symbols found in the bonus round, while Relax Gaming made sure to make Book of 99 even more exciting by throwing in a collection system you rarely see in releases like this.

Be on the lookout for the book symbol, as this will be your entry card to the most thrilling part of the game. It serves as the Wild, substituting for other regular icons and helping form more wins. However, it also works as the Scatter, triggering the bonus round and awarding ten spins when three or more land on the reels. Before the bonus round starts, a randomly chosen icon will become the expanding symbol, active throughout the feature.

Special symbols can expand to cover an entire reel on each spin. They also pay from any reel, which means they don’t have to be in adjacent positions. Filling an entire grid with special symbols is the ultimate goal, resulting in staggering payouts. To retrigger the Free Spins feature, all you have to do is land three or more Scatters.

Let’s talk about the game’s Wild collection system. Every time a Wild symbol lands during the Main Game, a collection meter located next to the screen will increase. Collecting 99 Wild will award ten free spins. Activating the bonus round functions the same way, with expanding symbols coming into play.
