How the Game Plays

Book of the Sphinx is an Egyptian-themed slot developed by IGT that takes you deep into the heart of a Pharaoh's tomb. The game features a classic 5-reel, 3-row setup where wins are formed by matching symbols across 20 fixed paylines. High-value symbols include Pharaohs, Scarabs, and Anubis statues, while traditional card royals handle lower payouts. The atmosphere is defined by stone-guarded grids and ancient artifacts, staying true to the popular archaeological exploration subgenre.

Free Spins Explained

The free spins bonus is triggered by landing three or more Book symbols anywhere on the reels. Depending on whether you land three, four, or five Books, you are awarded 10, 15, or 30 free spins respectively. Before the round begins, a random symbol is chosen to act as the special expanding symbol. When this symbol appears during the bonus, it expands to cover its entire reel, potentially leading to full-screen wins.

Eye of Ra Feature Explained

Distinct from the free spins round, the Eye of Ra symbol provides an additional layer of depth to the base game. If three or more Eye of Ra symbols land on a single spin, the feature activates. A random symbol (excluding the Book) is selected from the paytable, and all instances of the Eye of Ra on the grid transform into that symbol before expanding to fill their respective reels. This mechanic allows for significant wins without needing to enter the main bonus round.
