Big Brother 17
The Battle of the Block competition is a competition introduced in Big Brother 16. The twist was reintroduced as a "fan-favorite" during the premiere of Big Brother 17. The two pairs of nominees must compete against each other in a themed-competition. The winning pair would be safe from eviction for the week and would also dethrone the Head of Household that nominated them, leaving the other HOH as the sole Head of Household. It replaced the Have/Have-Not Competition in the early part of the game.
