The Houseguests enter the back yard to see a hill of rocks, with the nomination box at its center. Each Houseguest must stand on a pair of poles, placing their key inside the box. The Houseguests must keep one hand on their keys at all times. Throughout the competition, the platform beneath the Houseguests will jolt around, simulating an earthquake. The last player standing with a hand on their key will win the first round of the final Head of Household competition.
