Million Dollar Gamble

Challenge: Ferryman
Castaways are randomly divided into two teams of five. They start on a platform in the water, then swim out to a raft and work together to use a rope to pull themselves and the raft to another platform. From that platform, they climb up a ladder, retrieve a key, and then slide down a pole into the water. They must then race the key to shore. Once a team has all five of their keys, they unlock a set of blocks. The blocks then need to be stacked, so there are no repeating colors on any side. The first team to finish wins.
Reward: Trip to a floating restaurant to with pizza, chicken wings, and beer, within viewing range of the camp, and letters from home.
Winner: Purple Team (Adam Klein, Bret LaBelle, Hannah Shapiro, Sunday Burquest, and Zeke Smith)

Challenge: With a 10 ft Pole
Each castaway stand on a narrow beam while balancing a statue with a long pole. At regular intervals, they must move farther away from the statue making it more difficult to balance. If at any point, they fall off the beam or their statue drops, they are out of the challenge. The last person left standing wins immunity.
Winner: David Wright

Challenge: Slither Me Timbers
The castaways are randomly divided into three teams of three. Their feet are tied together and their arms are bound to their sides. One at a time they must slither through the sand through a series of obstacles. Finally, they must work together to solve a snake puzzle. First team to finish wins.
Additional Stipulation: At the beginning of the challenge, there is a rock draw to determine teams. The castaway who draws a white rock sits out for this challenge, and automatically joins the winning team on reward.
Reward: Aerial tour of the local area, followed by a feast
Winners: Orange Team (Bret LaBelle, Sunday Burquest, and Zeke Smith) (joined by David Wright)

Challenge: Rusty Gates
The castaways must each stand behind a cage door where they maneuver a handle through a maze. Once their handle is free, they unlock the door and race to complete a slide puzzle. The first person to finish wins immunity.
Winner: Jay Starrett
