 All the teams first work to eliminate the Red team (not wanting Q to get immunity) then the Brown team, then the Pink team .However, the Yellow team used strategy by placing their smaller weights on the scales first, keeping their heavier weights for later.This put the Grey team at a disadvantage – they have only the smaller weights to use on Yellow team, and although they started with a near 200-pound advantage on Yellow, Yellow catches up and eliminates Grey, thus winning immunity.
