Tournament Mode

Tournament Mode is a feature in Super Smash Bros. Melee and Super Smash Bros. Brawl, and Super Smash Bros. Tourney which features three modes:
 * Tournament
 * Loser out
 * Winner out

Tournament
In the tournament mode, players battle against each other in turns. Several options can be chosen for tournaments, including: In Brawl, there are some more options such as:
 * The number of competitors in a tournament (ranging from 4-64 (32 in Brawl), in two or four player tournaments and 6-27 in three player tournaments).
 * The number of computers and humans in a tournament.
 * How many players fight in each tournament match (In Melee, the number of players only go up when the certain number of controllers is inserted. When there are four controllers inserted, two to four players fight in each match, when there are three controllers inserted, two to three players fight in each match, and when there are one or two controllers inserted, two players fight in each match).
 * How stages are selected.
 * The CPU level of computer players (Levels 1-9 as well as a random option)
 * Individual custom rules for matches.
 * Handicap for individual players and computers.
 * Set a player to "Drop out" computers that will automatically drop out when their match comes so that people can play with uneven amounts of players.
 * One can switch between Samus-Zero Suit Samus, Zelda-Sheik and Pokemon Trainer and his pokémon by using "-" on a Wii remote, Left Control Stick on Classic Controller, C on Wii remote + Nunchuck, and the C Stick on Gamecube Controller. In Tourney, this cannot be done as the characters are now separated.

Loser out
This mode is also played in turns, but unlike Tournament, where the game ends when a final winner is proclaimed, this lasts forever (or at least until the player decides to stop playing). The loser of each match "drops out" and has to wait until it is his or her turn again.

Winner in
This mode is an extension of Loser Out. It is used for Free for All matches containing 3 or 4 players. When a match is complete, all players except the winner swap out. If four players are in each match, the three losers will swap out. Similarly, in 4-player Free for All matches, players may choose to keep the best two players in, while the other two swap out.

Winner out
This mode is exactly the same as the aforementioned loser out mode, except that the winner of each match drops out instead of the loser.

Trivia

 * Ironically, the Tournament mode is not used in actual competitive play.
 * Exclusively in Super Smash Bros. Tourney, the champion does one of his/her victory animation after the Tournament.
