In some sports, this extra period is played only if the game is required to have a clear winner, as in single - elimination tournaments where only one team or players can advance to the next round or win the tournament . In other sports, particularly those prominently played in North America where ties are generally disfavored, some form of overtime is employed for all games . </P> <P> The rules of overtime or extra time vary between sports and even different competitions . Some may employ "sudden death", where the first player or team who scores immediately wins the game . In others, play continues until a specified time has elapsed, and only then is the winner declared . If the contest remains tied after the extra session, depending on the rules, the match may immediately end as a draw, additional periods may be played, or a different tiebreaking procedure such as a penalty shootout may be used instead . </P>
