# Tournaments

Filler supports a tournament mode. You can play tournaments when you want the robot players to play amongst themselves, or if you simply want to assert your authority over them. The forms of tournament are:

Round robin
  There is no winner in this form of tournament. All players play all other players.
Knockout
  Once a player loses a match, they are eliminated from the tournament. The last player not eliminated wins. Players play a roughly equal number of matches.
Basho
  This form of tournament is based on sumo tournaments. There are a fixed number of rounds. Each player plays against other players of similar ability. The player with the most wins at the end wins the tournament. If multiple players have the same number of wins, round robin elimination rounds are played as well.
Challenge
  Human players may not participate in this form of tournament. The computer players challenge each other attempting to improve their rankings. There is no winner.

To configure and run a tournament, go to the Tournament Panel. The first column lets you choose the rules for the tournament, which are restricted to the form of the tournament. The Continuous checkbox lets you choose that once a tournament has finished, a new one starts immediately. The Description panel gives you a brief summary of the tournament rules.

The second column is the list of players selected to play in the tournament. The players are ordered in descending order of rating. Initially, all players are selected.

The third column contains a Description panel, describing the player last selected or deselected in the Players list. At the bottom of the third column is the "Play Tournament" button. Clicking this button will switch the game to the Play panel and start the tournament.
