The Book of 99 slots enables you to walk with the Greek warriors on a journey of undiscovered lands, and defend against the evil ploy of fantastical creatures.

You can grab this win by gaining the maximum of 10 free spins which paves the way to collecting the Bonus Round, providing players the opportunity to fill up the entire meter. Besides this promising award, players are also granted an unbelievable RTP of 99%. Some might consider the high volatility as the key drawback, but every Relax Gaming slot is marked with high volatility. So this towering RTP is undoubtedly a key differentiator.

Another similar slot, "Iron Bank" fetches a slightly lower multiplier of 2000x at an RTP of 96.20%. To get started, players can use the Book of 99 demo mode before indulging in real money.
