The Challenge (1998) : 14x12

Players from each team have to transfer hand-carved wooden giraffes across a lake, to one of 15 cages that contains an identical twin giraffe. There are numerous giraffes on the shore across the lake that are in different shapes and sizes, and before advancing across the lake, each player has to randomly uncover one of 15 cages at the start of the course that are covered with white tarps, then memorize the details of the caged wood-carved giraffe inside, then swim across the lake to find the identical matching twin, with a key that will unlock a player's designated cage at the start of the course. Each player will have a 30-minute time limit, and the team that completes the challenge in the fastest average time wins.
