<P> Of the 36 full series played, Queensland have won 21, New South Wales 14, with 2 series drawn (Queensland retained the Shield on both occasions as the previous year's winner). With the addition of three one - off games that were played in 1980, 1981 and 1987, the total number of games played is 108 . Queensland have won 58, New South Wales have won 51, with 2 matches being drawn . </P> <P> The series of 1999 and 2002 are considered drawn series, as both New South Wales and Queensland won a single game of each 3 match series, with the final game concluding in a draw . At that time there was no overtime rule to break the deadlock, and by the same set of rules, Queensland retained the shield as they were the previous holders, but did not win the series . Due to controversy around the second drawn series, and the rule awarding the series champions to Queensland, the rules were subsequently changed to rule out drawn matches and series . Equal points at the close of full - time are now resolved with the golden point method . </P> <Table> <Tr> <Th_colspan="6"> State of Origin series </Th> </Tr> <Tr> <Th> Year </Th> <Th> Winner </Th> <Th> Wins </Th> <Th> Losses </Th> <Th> Drawn </Th> <Th> Shield Holder </Th> </Tr> <Tr> <Td> 1982 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1984 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1985 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1986 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1988 </Td> <Td> Queensland </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1989 </Td> <Td> Queensland </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1990 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1991 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1992 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1993 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1994 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1995 </Td> <Td> Queensland </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> </Td> <Td> New South Wales </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1997 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 1998 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 1999 </Td> <Td> Draw </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2000 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 2001 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2002 </Td> <Td> Draw </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2003 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 2005 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 2006 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2007 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2008 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2009 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> </Td> <Td> Queensland </Td> <Td> </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2011 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2012 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2013 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2014 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> <Tr> <Td> 2015 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2016 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2017 </Td> <Td> Queensland </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> Queensland </Td> </Tr> <Tr> <Td> 2018 </Td> <Td> New South Wales </Td> <Td> </Td> <Td> </Td> <Td> 0 </Td> <Td> New South Wales </Td> </Tr> </Table> <Tr> <Th_colspan="6"> State of Origin series </Th> </Tr>
