Book of 99 - Ancient Egyptian Slot

Discover why Book of 99 has become a cult favorite at Bahigo Casino. Developed by Relax Gaming, this 5×3 slot blends classic “Book” mechanics with an extraordinary twist: a 99% RTP. That headline number means the game is engineered for unusually strong long-term returns compared with typical online slots, while still delivering the suspense and volatility fans expect.

The theme taps into Greek myth. Ancient ruins and heroic symbols set the scene, with the Book icon acting as both Wild and Scatter. Three Books trigger Free Spins—a special feature where one symbol is randomly chosen to become an expanding symbol. When enough of that symbol lands, it expands to cover its reels and pays on all lines, even if the symbols are not adjacent, recreating the high-impact moments that made “Book” games famous.

Book of 99 also introduces a clever collection mechanic: each time a Book appears in the base game, it fills a meter. Reach 99 collected Books and you guarantee a Free Spins round, even if you didn’t land three scatters at once. This system softens dry streaks and builds anticipation, giving you a tangible milestone to chase during regular play.
