Discover Huge Returns Of 99% From The New Book of 99 Online Slot By Relax Gaming

Relax Gaming has revealed a brand-new slot with a Greek theme and a massive Return To Players percentage. Book of 99 pays back at an average rate of 99%.

Players will find incredible 99% average returns from the Book of 99 slot that's just been released by Relax Gaming. This Ancient Greek-themed game features free spins with expanding symbols, and wins that can reach 5,000x the bet.

Discover A Mysterious Book

Heroic characters, a cyclops, and harpy appear on the 5 reels, 10 paylines cross the game, and alongside the character symbols, players will encounter high card emblems and a powerful book. This is both the wild symbol, which can act as others to complete wins, and scatter symbol of the Book of 99 slots game.

Each time the book appears, it collects in a meter to the side of the reels, and once 99 are in there, they trigger a free spins bonus round. Before they begin, the game selects a random symbol which expands to fill any reel it lands on during the 10 free games. The chosen symbol doesn't have to be on adjacent reels to award a prize.

An Amazing Return To Players Percentage

The Book of 99 slot gets its name from the number needed to trigger the free games, but also from the almost unheard of Return To Players percentage of 99%. That gives players incredible value for money when they open up the mobile and desktop versions. It's a high volatility slot, with a bet range of 0.10 to 100.00 per spin.

Commenting on the launch, Simon Hammon, CPO at Relax Gaming said: “The ‘Book of’ genre is a well-read one, but as always, our development team has done an amazing job in re-defining its legacy - marking Book of 99 as a game that truly stands out among the competition.


“It’s not only the generous 99% RTP that makes this game stand tall, but also a great slot experience in its own right, with a host of engaging features ready to wow its audience. We’re looking forward to seeing what players make of our new approach!”
