The Maze

The Maze (often given a location-specific name for each season) is a recurring Immunity Challenge that tests both physical and mental prowess. It premiered in and multiple variations of the challenge have appeared in different stages of the game.

Rules
The contestants (sometimes in tribes, but usually individually) head into a labyrinth of passages, corridors, and turns. They have to reach a certain number of checkpoints either in order or any order they wish, collecting an item at each one. After they collect all their items, contestants must find their way out of the maze. Mazes have also been done where the castaways are blindfolded, called a Braille Maze.

History
The challenge made its debut in . The tribes had to collect five pendants in the correct numerical order. Because there was no apparent unfairness due to having a maze for each tribe, everyone in the competition competed. Ogakor maintained the lead early and Kucha was unable to catch up. Ogakor won immunity for the first time in days.

The challenge returned in. The format was similar to The Australian Outback. Rob Mariano lead Rotu to victory.

The challenge's next appearance (called Obstacle Puzzle Maze) was in as the final four Immunity Challenge. Unlike its previous two appearances, it was an individual challenge. The castaway had to collect eight ladder rungs in any order. After the castaways had obtained them all, they must arrang them in the correct order to reach the top of the platform. The first person to do so wins. Everyone was relatively even, although Rupert Boneham had a slight lead. In the end, Amber Brkich caught up and passed him. Amber won immunity for the first time in the game.

The challenge was also used in  as the final four Immunity Challenge, where it was known as Snakes and Ladders. This time, the maze was vertical. The castaway had to collect eight bags of puzzle pieces. After collecting all of the bags, they must arrange them to spell out "Final Three". The first person to do so wins. Scout Cloud Lee was quickly out of the challenge due to her age. In a close race, Chris Daugherty was the first to compete the puzzle, winning himself immunity.

The challenge reappeared in  as the final four Immunity Challenge (and was known as Maya Maze). The castaways had to collect pieces and arrange them to form a Mayan deity. Everyone was somewhat even, with the exception of Lydia Morales who was lagging. Rafe Judkins was the first to complete the puzzle, winning immunity.

In, the challenge (here called A-Mazing Gabon) was used as the final five Immunity Challenge. The castaways had to dig a hole under a wall, cross a maze made out of planks, and untie a series of knots that would open a gate that led to a maze with 25 Gabonese huts. They should find three bags of puzzle pieces in the huts and take them one at a time to a platform. Bob Crowley got the three bags and finished the puzzle first, winning immunity.

The challenge reappeared in  as the Final Immunity Challenge. Called Meso Maze, it once again saw the castaways collecting puzzle pieces to ultimately spell out a phase. It was neck and neck between Rob Mariano and Ashley Underwood. They even helped each other out on the puzzle. Rob was the one who competed his puzzle first and won immunity.

In the challenge was once again used as the Final Immunity Challenge. In this version, called Roundabout, the final three have to race out into a maze with turnstiles where they have to collect four medallions. Once they have all four medallions, they then have to use them to open a chest, inside of which are puzzle pieces in the form of wooden cogs. Once the puzzle is put together, they then have to turn the cogs raising a flag. The first player to raise the flag wins immunity. Kass McQuillen was initially leading, however, she became stuck looking for her last piece. This allowed Woo Hwang and Tony Vlachos to catch up and start on the puzzle. Despite Kass coming from behind, Woo beat her by a second for the final immunity.
