Season 1

Before one of the three finalists is crowned champion, a shocking twist brings familiar faces back to the house who attempt to influence the game one last time. The final challenge is the classic game of Truth or Dare, where the stakes have never been higher as the winner automatically receives a spot in the top two. Strategy and tough decisions make for the most revealing challenge yet, ultimately ending in a tie and forcing a head-to-head dare to declare the winner. Alliances continue to be tested, and more secrets than ever are shared; but in the end, only one competitor outsmarts the rest, earning his or her own "Claim to Fame" and taking home the $100,000 prize.

After a dramatic Guess Off, the remaining four housemates grapple with loyalty, betrayal and their moral compasses while inching closer to victory. The challenge tests the contestants' knowledge about the celebrity relatives with clues pointing to their nicknames, careers, celebrity romances and TV appearances. For a second week in a row, the winner does not receive immunity but does receive the final wine room clue. The final Guess Off before the finale is an emotional one.

An alliance is solidified between two housemates. One housemate continues to lead others on with her false identity. A trivia challenge tests pop-culture knowledge.

With only six contestants remaining, the competition is stiff, and loyalties are tested; this week's challenge is centered on a mock estate sale, where the contestants must spot the difference when certain items are swapped around.

Attached to a lie detector, contestants take turns sitting in the hot seat answering yes or no questions about their relatives; they must decide whether to tell the truth or lie, while attempting to give their best poker face.

As the contestants catch on to Dominique's influence throughout the house, some develop their own counterstrategies; an elaborate game of telephone puts teams' memorization and communication skills to the test.

A fashion show challenge forces the players to create and show off a look centered around one item of clothing that reveals a clue about themselves; the winner of the challenge receives information about a fellow housemate; there is speculation that Dominique has the ability to influence others in the game.

With 10 contestants remaining, alliances continue to form and be tested throughout the house as more guesses are made; the contestants split up into two teams and jump into the pool, with one contestant saying goodbye.

New alliances are formed and more identities revealed after the first elimination; a close round of voting in the Voto Booth ends in another elimination.
