A "Perfect Game" is a feat that has been accomplished by only four houseguests: Dan Gheesling, Kevin Martin, Dane Rupert and Cody Calafiore.
Elements of a Perfect Game
- The houseguest never receives an eviction vote against him or her.
- The houseguest is announced the winner of Big Brother.
- The Jury unanimously votes for the houseguest to win.

Those Who Almost Played a Perfect Game
Trivia
- The concept of a Perfect Game also exists in Survivor. To be considered to have played a Perfect Game in Survivor, a contestant must never receive an elimination vote during the game and must then win the game by a unanimous vote from the Jury. As in Big Brother, a perfect game is a rare accomplishment, and has only been achieved twice by winners J.T. Thomas in Survivor: Tocantins and John Cochran in Survivor: Caramoan.
- Due to Cody never being nominated at all, including at Final 3 due to winning the Final HOH, he has the most Perfect Game of all four winners. Dan, Kevin and Dane all won their respective Final HOHs, but got nominated beforehand at some point during their seasons.
- Had Ian received all of the jury votes to win during Big Brother 14 (US), Dan would have been the first houseguest to play a Perfect Game and lose to a Perfect Game.
- Had Dan won the season with all seven votes by the Jury, he would have been the only person to win with a Perfect Game twice.
- Dan and Cody are the only people to eligible to win with a Perfect Game twice.
- All 7 winners of Big Brother Canada have never received any eviction votes, although Kevin and Dane are the only ones to win with a Perfect Game.
- Ironically, the first 6 runners-up of Big Brother Canada were unable to win with a Perfect Game, as they all had received at least 1 eviction vote before reaching the Final 2. Anthony Douglas was the first Canadian runner-up who had the opportunity to achieve a Perfect Game.
- For Big Brother 1 (US) and Big Brother: Over The Top, the concept of a Perfect Game is different.
- For Big Brother 1 (US), a housemate would have had to never receive any percentage of America's vote to banish and have had to receive 100% of America's vote to win.
- For Big Brother: Over The Top, a houseguest would have had to never receive an eviction vote and have had to receive 100% of America's vote to win.
- Because of the stipulation of having to receive 100% of America's vote to win, a Perfect Game in Big Brother 1 (US) or Big Brother: Over The Top is virtually impossible.
- Kevin is the first winner to have received all of the Jury votes from a Jury of 9. However, he is not the first winner to win with 9 votes. Lisa Donahue did so in Big Brother 3 (US).
- Tamar Braxton is the first person to win the game with a unanimous vote but not a Perfect Game.
- She's also the first female to win with a unanimous vote.
- As of Big Brother Canada 8 and Big Brother 22 (US), no woman has ever won with a Perfect Game. Only Tamar has come the closest, winning unanimously but having one eviction vote cast against her.
