Escape the Sunken Pyramid: The Story and a Look Inside

Escape the Sunken Pyramid is a puzzle adventure gamebook, so do not read it in order. You solve a puzzle, and the answer in the door brick is the page you turn to next.

The story

A stepped pyramid rests on the sea floor beside Tidewell, a deep-sea research station. You follow Otto the octopus through the Sea Gate; it seals behind you, and a ramp spirals up round nine levels of five chambers to the Apex Hatch.

The map is the pyramid seen from above, a square spiral. One lock, Sonar Echoes, shows only the gap between the two bricks under each buoy, with an arrow to the bigger one.

How it plays

Every chamber is one page: a short story beat, a puzzle, and a Next Door box. Solve the puzzle, find the number in the door brick, and turn to that page. A wrong answer sends you to a dead end that tells you which brick to recheck, so a slip costs you a minute and not the whole game.
