<P> During Season 18, the first two evicted house guests battled one on one, and the winner went on to compete against the third . The winner of that matchup would face the next evicted HouseGuest, and the winner of the final match - up re-entered the game . Victor Arroyo was the winner . Also that season, jury members competed alongside the HouseGuests still in the game . The last HouseGuest standing became the new HoH while the last Jury member standing returned to the game . Victor won this Battle Back making him the first HouseGuest in Big Brother history to reenter the game in the same season for a third time . This version of the Battle Back did not return for season 19 . </P> <P> During Season 19, the four evicted house guests played against each other in one competition . The top two then played head - to - head, and the winner then had to face off against a member inside the house . If the evicted house guest won, they would re-enter the game . However, if the non-evicted house guest won, no one would re-enter the game and all four evicted house guests would be permanently eliminated . Cody Nickson beat Paul Abrahamian in the final round and reentered the game . </P> <Table> <Tr> <Th> Season </Th> <Th> Launch date </Th> <Th> Finale date </Th> <Th> Days </Th> <Th> HouseGuests </Th> <Th> Winner </Th> <Th> Runner - Up </Th> <Th> Final Vote </Th> <Th> Average viewers (millions) </Th> <Th> Episodes </Th> </Tr> <Tr> <Th> </Th> <Td> July 5, 2000 </Td> <Td> September 29, 2000 </Td> <Td> 88 </Td> <Td> 10 </Td> <Td> Eddie McGee </Td> <Td> Josh Souza </Td> <Td> 59--27--14% </Td> <Td> 9.10 </Td> <Td> 70 </Td> </Tr> <Tr> <Th> </Th> <Td> July 5, 2001 </Td> <Td> September 20, 2001 </Td> <Td> 82 </Td> <Td> 12 </Td> <Td> Will Kirby </Td> <Td> Nicole Schaffrich </Td> <Td> 5--2 </Td> <Td> 7.90 </Td> <Td> 30 </Td> </Tr> <Tr> <Th> </Th> <Td> July 10, 2002 </Td> <Td> September 25, 2002 </Td> <Td> Lisa Donahue </Td> <Td> Danielle Reyes </Td> <Td> 9--1 </Td> <Td> 8.70 </Td> <Td> 33 </Td> </Tr> <Tr> <Th> </Th> <Td> July 8, 2003 </Td> <Td> September 24, 2003 </Td> <Td> 13 </Td> <Td> Jun Song </Td> <Td> Alison Irwin </Td> <Td> 6--1 </Td> <Td> 8.80 </Td> <Td> 33 </Td> </Tr> <Tr> <Th> 5 </Th> <Td> July 6, 2004 </Td> <Td> September 21, 2004 </Td> <Td> 14! 14 </Td> <Td> Drew Daniel </Td> <Td> Michael "Cowboy" Ellis </Td> <Td> 4--3 </Td> <Td> 8.30 </Td> <Td> 31 </Td> </Tr> <Tr> <Th> 6 </Th> <Td> July 7, 2005 </Td> <Td> September 20, 2005 </Td> <Td> 80 </Td> <Td> 14 </Td> <Td> Maggie Ausburn </Td> <Td> Ivette Corredro </Td> <Td> 7.24 </Td> <Td> 30 </Td> </Tr> <Tr> <Th> 7 </Th> <Td> July 6, 2006 </Td> <Td> September 12, 2006 </Td> <Td> 72 </Td> <Td> 14! 14 (All Returnees) </Td> <Td> Mike "Boogie" Malin </Td> <Td> Erika Landin </Td> <Td> 6--1 </Td> <Td> 7.56 </Td> <Td> 28 </Td> </Tr> <Tr> <Th> 8 </Th> <Td> July 5, 2007 </Td> <Td> September 18, 2007 </Td> <Td> 81 </Td> <Td> 14 </Td> <Td> "Evel" Dick Donato </Td> <Td> Daniele Donato </Td> <Td> 5--2 </Td> <Td> 7.52 </Td> <Td> 33 </Td> </Tr> <Tr> <Th> 9 </Th> <Td> February 12, 2008 </Td> <Td> April 27, 2008 </Td> <Td> 16 </Td> <Td> Adam Jasinski </Td> <Td> Ryan Quicksall </Td> <Td> 6--1 </Td> <Td> 6.56 </Td> <Td> 33 </Td> </Tr> <Tr> <Th> 10 </Th> <Td> July 13, 2008 </Td> <Td> September 16, 2008 </Td> <Td> 71 </Td> <Td> 13 </Td> <Td> Dan Gheesling </Td> <Td> Memphis Garrett </Td> <Td> 7--0 </Td> <Td> 6.72 </Td> <Td> 29 </Td> </Tr> <Tr> <Th> 11 </Th> <Td> July 9, 2009 </Td> <Td> September 15, 2009 </Td> <Td> 73 </Td> <Td> 13! 13 (1 Returnee) </Td> <Td> Jordan Lloyd </Td> <Td> Natalie Martinez </Td> <Td> 5--2 </Td> <Td> 7.19 </Td> <Td> 30 </Td> </Tr> <Tr> <Th> 12 </Th> <Td> July 8, 2010 </Td> <Td> September 15, 2010 </Td> <Td> 75 </Td> <Td> 13 </Td> <Td> Hayden Moss </Td> <Td> Lane Elenburg </Td> <Td> 4--3 </Td> <Td> 7.76 </Td> <Td> 30 </Td> </Tr> <Tr> <Th> 13 </Th> <Td> July 7, 2011 </Td> <Td> September 14, 2011 </Td> <Td> 14! 14 (6 Returnees) </Td> <Td> Rachel Reilly </Td> <Td> Porsche Briggs </Td> <Td> 7.95 </Td> <Td> 29 </Td> </Tr> <Tr> <Th> 14 </Th> <Td> July 12, 2012 </Td> <Td> September 19, 2012 </Td> <Td> 16! 16 (4 Returnees) </Td> <Td> Ian Terry </Td> <Td> Dan Gheesling </Td> <Td> 6--1 </Td> <Td> 6.79 </Td> <Td> 30 </Td> </Tr> <Tr> <Th> 15 </Th> <Td> June 26, 2013 </Td> <Td> September 18, 2013 </Td> <Td> 90 </Td> <Td> 16 </Td> <Td> Andy Herren </Td> <Td> GinaMarie Zimmerman </Td> <Td> 7 - 2 </Td> <Td> 6.47 </Td> <Td> 36 </Td> </Tr> <Tr> <Th> 16 </Th> <Td> June 25, 2014 </Td> <Td> September 24, 2014 </Td> <Td> 97 </Td> <Td> Derrick Levasseur </Td> <Td> Cody Calafiore </Td> <Td> 6.41 </Td> <Td> 40 </Td> </Tr> <Tr> <Th> 17 </Th> <Td> June 24, 2015 </Td> <Td> September 23, 2015 </Td> <Td> 98 </Td> <Td> 17! 17 </Td> <Td> Steve Moses </Td> <Td> Liz Nolan </Td> <Td> 6--3 </Td> <Td> 6.18 </Td> <Td> 40 </Td> </Tr> <Tr> <Th> 18 </Th> <Td> June 22, 2016 </Td> <Td> September 21, 2016 </Td> <Td> 99 </Td> <Td> 16 (4 Returnees) </Td> <Td> Nicole Franzel </Td> <Td> Paul Abrahamian </Td> <Td> 5--4 </Td> <Td> 5.78 </Td> <Td> 42 </Td> </Tr> <Tr> <Th> 19 </Th> <Td> June 28, 2017 </Td> <Td> September 20, 2017 </Td> <Td> 92 </Td> <Td> 17 (1 Returnee) </Td> <Td> Josh Martinez </Td> <Td> 6.06 </Td> <Td> 39 </Td> </Tr> <Tr> <Th> 20 </Th> <Td> June 27, 2018 </Td> <Td> Fall 2018 </Td> <Td_colspan="7"> TBA </Td> </Tr> </Table> <Tr> <Th> Season </Th> <Th> Launch date </Th> <Th> Finale date </Th> <Th> Days </Th> <Th> HouseGuests </Th> <Th> Winner </Th> <Th> Runner - Up </Th> <Th> Final Vote </Th> <Th> Average viewers (millions) </Th> <Th> Episodes </Th> </Tr>
