In the tournament mode, players battle against each other in turns. Several options can be chosen for tournaments, including:
The number of competitors in a tournament (ranging from 4-64 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
How stages are selected
The CPU level of computer players (Levels 1-9 as well as a random option)
Individual custom rules for matches
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.
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.
