Book of Xerxes brings the timeless “Book” formula into the world of ancient Persian legends, blending a 5×3, 10‑line setup with expanding Bonus symbols and a clean, high‑impact Free Games feature. With its familiar structure, strong volatility curve, and the iconic Book acting as both Wild and Scatter, the game delivers a streamlined, classic experience built for players who love the traditional Book‑style thrill.
Book of Xerxes 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 all regular symbols and triggering Free Games when three or more appear. During Free Games, a random symbol becomes the expanding Bonus symbol, unlocking the signature “Book” mechanic.


The game embraces an ancient‑Egypt‑meets‑Persian aesthetic, with golden books, royal symbols, and desert‑temple tones. The reels feel mystical and regal, evoking the secrets of Xerxes’ hidden library. The expanding Bonus symbol animation adds a dramatic flourish, filling entire reels with golden overlays and creating the classic Book‑style suspense.

The Book substitutes for all symbols except Bonus symbols during Free Games. As a Scatter, it pays anywhere on the reels and triggers the Free Games feature when three or more land.

Three, four, or five Books award 10 Free Games. Free Games use a special reel set and play with the same bet as the triggering spin. Additional Free Games can be retriggered.
At the start of Free Games, one of the nine regular symbols is chosen as the Bonus symbol. When enough Bonus symbols land to form a winning combination, they expand to cover their entire reels after the regular evaluation. Expanded Bonus symbols pay as “scatter‑on‑payline,” meaning gaps are ignored and wins are evaluated along paylines regardless of reel position. Bonus symbols do not participate in the regular payline evaluation.
Book of Xerxes includes a Buy Feature that lets players purchase instant entry into the Free Games feature at a cost tied to the current bet. Buying the feature uses a slightly higher RTP, giving players a more favorable return profile when skipping straight to the expanding‑symbol action. It’s the fastest way to reach the signature Book mechanic without waiting for natural triggers.

Book of Xerxes focuses on the pure, classic Book‑slot experience: 10 Free Games, expanding Bonus symbols, and the iconic dual‑purpose Book driving all the action. The gameplay is clean and direct, making it ideal for players who want the familiar expanding‑symbol suspense without extra layers or distractions. With its polished presentation and traditional volatility curve, it delivers exactly what Book‑style fans expect.
