How the Game Plays

Book of Secrets Extra by Synot Games is an enhanced version of the provider's popular archaeological adventure. The game invites you to accompany a fearless female explorer as she ventures deep into an ancient pyramid in search of the Golden Book. The 5x3 reel set is populated with classic Egyptian motifs, including Pharaoh masks, scarab beetles, ankhs, and stylized card royals. Winning combinations are formed by landing matching symbols across the 10 fixed paylines, with the Archaeologist serving as the highest-paying standard symbol.

Free Spins Explained

The core of the action centers on the Golden Book symbol, which functions as both the Wild and the Scatter. Landing three or more Book symbols anywhere on the reels triggers 10 free spins. Before the round begins, a random symbol is selected to become the Special Expanding Symbol. During the feature, this symbol expands to cover its entire reel if a win can be formed, paying out across all paylines regardless of whether the symbols are on adjacent reels.

Bonus Buy & Gamble Feature

This "Extra" edition distinguishes itself from the original title by including a Bonus Buy option, allowing you to bypass the base game and enter the free spins round directly. Furthermore, the game features a traditional risk-based Gamble mechanic. Following any base game win, you can choose to guess the color of a hidden card to double your payout, with the option to gamble up to 10 times or halve the current win to bank a portion.
