Knight Moves

 (also known as Turnover) is a recurring Power of Veto and Battle of the Block competition.

Rules
Houseguests all pick a tile to start on and flip it over. They must then take one step in any direction and flip over the tile. That tile is out of play and houseguests cannot step on that tile ever again. Houseguests continue until they can no longer take a step in any direction. When that occurs, the houseguest is out of the competition.

This process continues until one person is left standing. That person wins the PoV or BotB.

History
The competition first appeared on Big Brother 3. Houseguest Chiara Jude Berti won the competition, winning her first PoV of the summer.

The competition reappeared on Big Brother 6. Houseguest James Rhine won the competition, winning his second PoV of the season.

Reappearing on Big Brother 16, the competition was now a Battle of the Block competition. Houseguests Amber Borzotra and Jocasta Odom won the competition, meaning they were safe for the week.
