Braille Maze

Braille Maze (also known as Blind Maze) is a recurring Individual Immunity Challenge that debuted in, and has since reappeared in and.

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") insignia's 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 of the maze wins the challenge.

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

In  the challenge was extended and modified. Each contestant had a uniquely shaped key that fit into 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.

The challenge next appeared as the Final Immunity Challenge in. The contestants had to collect four necklaces (again representing the four elements) scattered throughout the maze, then make their way to the Immunity Necklace located at the maze exit. The challenge reached a nail-biting finish, as Russell Hantz edged out Parvati Shallow and Jerri Manthey by mere inches to claim immunity. It was Russell's second individual immunity of the season.
