Braille Maze

Braille Maze (also known as A-Mazing Gabon) is a recurring individual immunity challenge that first appeared in, and has since reappeared in. The challenge has always appeared as the penultimate immunity challenge.

Rules
Each contestant is blindfolded, and must make their way through a maze whilst accomplishing given tasks (such as collecting medallions). Throughout the maze, signposts with raised (or "braille") insignias help to point the castaways in the direction of items or the end of the maze. The first contestant to accomplish all required tasks and reach the end point wins the challenge.

History
The challenge debuted in at the Final Four. The contestants were required to locate medallions representing the four elements (earth, air, fire and water) and return them to the center of the maze. Jenna Morasca won the challenge, taking home her second individual immunity.

saw the challenge extended and modified. Each contestant had a uniquely shaped key that they used to locate a unique gate. The key unlocked the gate and dropped a drawbridge to permit access to the next stage of the maze (which grew larger and more complex over the five maze stages). Yau-Man Chan won the challenge and his second individual immunity.
