Another three - player variation is " Sevens " in which one player plays against two players as a team , with the game being played to seven points ; if the two player team gets to seven first , the game is over , but if the solo player gets to seven first then the game continues to 14 ; if the solo player again reaches 14 first , then the game continues to 21 , where the game ends regardless of whether the solo player or the two player team reach 21 first .
