Big Brother 1

 is the second season of Big Brother (U.S.).

Twists

 * Have-Not Choosing: After the first Have-Nots were determined by the first HOH competition, they then had to pick the new Have-Nots themselves for the following week, and the process repeated every week. They are not allowed to pick any other outgoing Have-Nots, including themselves. In Week 5, there were no Have-Nots for the week, and the Week 6 Have-Nots were also determined by a competition, before starting the new selection cycle in Week 7. If an outgoing Have-Not was evicted, there would be no replacement and the number of overall Have-Nots would just decrease.
 * Room Twist: New rooms will be added to the house throughout the season, each with its own special twist.
 * Safety Suite Competition: For the first three weeks, the All-Stars were given a VIP Pass to the Safety Suite. Once a signal went off, they had an hour to decide if they wanted to swipe their pass and play in the competition. The winner would get safety for the week and could gift it to a "Plus One", making two people immune. The Plus One would receive a punishment in exchange for being safe. The current HOH is ineligible to enter the Safety Suite, and a houseguest can only enter the Safety Suite once before being ineligible for future rounds. If only one houseguest enters the Safety Suite, they will not be guaranteed safety - they will still have to complete the competition before their time runs out in order to win safety.
 * BB Basement: In Week 5, the houseguests will compete in a Black Box competition, and three houseguests will win. The three winners will each receive their own power that has the ability to shake-up the game.
 * The Disruptor: Keo Motsepe won the power to secretly save a nominee and force the HOH to name a replacement. Whoever he saves will be safe, but unless he uses it on himself, he will still be vulnerable. It can be used following any of the next three Nomination Ceremonies.
 * The Replay: Jesse Metcalfe won the power to allow any outgoing HOH to play the HOH the following week. He can use it on herself or anyone else. It can be used during the next three HOH competitions.
 * The Blocker: Vernon Davis won the power to block himself, or someone else, from being nominated post-Veto. If he wins the Veto and saves a nominee, he can also block another houseguest of her choosing from going up. He must use it after the POV is used but before the HOH names a replacement nominee. It can be used at one of the next three Veto Meetings.
 * Triple Eviction: In Week 8, two weeks of Big Brother will go down in one night during the first-ever Triple Eviction. Two HOH competitions, two POV competitions, and three evictions all in one night!
