How the Game Plays

Book of Mystery Pyramids by Onlyplay is a visually polished addition to the Egyptian genre, set within the dimly lit chambers of an ancient tomb. The game follows a traditional 5x3 grid structure where wins are formed by matching symbols from left to right across 10 fixed paylines. The paytable features thematic icons including scarabs, pharaohs, and an adventurous explorer, alongside stylized card suits. A unique strategic element is the Paid Respin feature, which allows you to select any individual reel to respin for a calculated cost after a standard spin, helping to complete winning lines or trigger features.

Free Spins Explained

Landing three or more Book symbols triggers the Free Spins mode. Before the round begins, the game randomly selects one standard symbol to act as a special expanding symbol. During the bonus, if enough of these symbols land anywhere on the grid, they expand vertically to cover their entire reels and pay out across all 10 lines, even if they are not on adjacent reels. This feature can be retriggered by landing additional scatters during the round.

Speed Up Feature Explained

This Onlyplay title includes a "Speed Up" option, which serves as a Bonus Buy mechanic. It allows you to bypass the base game and instantly trigger the Free Spins round for a fixed multiple of your current stake, providing immediate access to the expanding symbol mechanic.
