How to Play Book of Xerxes – Diamond Treasures

The game is played on a 5×3 reel layout with 10 fixed paylines. Wins form by landing identical symbols on adjacent reels from left to right. The Book symbol acts as both Wild and Scatter, substituting for regular symbols and triggering Free Games when 3 or more appear anywhere on the reels. The Diamond Treasures side game can be activated for an additional bet, adding a random prize‑draw mechanic on top of the base game.

Book of Xerxes Theme & Graphics

Book of Xerxes presents a mystical, fantasy‑styled version of ancient Egypt. Golden books, enchanted relics, and arcane symbols fill the reels, while the atmosphere leans into adventure and mystery rather than strict historical realism. The presentation is clean and polished, with dramatic animations during Bonus Symbol expansions and Diamond Treasures prize draws. It’s a classic Book‑slot aesthetic with a modern, magical twist.
