A single-elimination, knockout, or sudden death tournament is a type of elimination tournament where the loser of each match-up is immediately eliminated from the tournament. Each winner will play another in the next round, until the final match-up, whose winner becomes the tournament champion. Each match-up may be a single match or several, for example two-legged ties in European sports or best-of series in American pro sports. Defeated competitors may play no further part after losing, or may participate in "consolation" or "classification" matches against other losers to determine the lower final rankings; for example, a third place playoff between losing semi-finalists. In a shootout poker tournament, there are more than two players competing at each table, and sometimes more than one progressing to the next round. Some competitions are held with a pure single-elimination tournament system. Others have many phases, with the last being a single-elimination final stage, often called playoffs.

A penalty shoot-out is a tie-breaking method in association football to determine which team is awarded victory in a match that cannot end in a draw, when the score is tied after the normal time as well as extra time have expired. In a penalty shoot-out, each team takes turns shooting at goal from the penalty mark, with the goal defended only by the opposing team's goalkeeper. Each team has five shots which must be taken by different kickers; the team that makes more successful kicks is declared the victor. Shoot-outs finish as soon as one team has an insurmountable lead. If scores are level after five pairs of shots, the shootout progresses into additional "sudden-death" rounds. Balls successfully kicked into the goal during a shoot-out do not count as goals for the individual kickers or the team, and are tallied separately from the goals scored during normal play. Although the procedure for each individual kick in the shoot-out resembles that of a penalty kick, there are some differences. Most notably, neither the kicker nor any player other than the goalkeeper may play the ball again once it has been kicked.
