Listed below are the available choices: (PrezCon can no longer allow ‘Free Form’ Tournaments.)
SWISS ELIMINATION [SwEl]: Any system using a number of preliminary rounds in order to advance a pre-determined number of finalists into a Single-Elimination (SE) format. It is often used in conjunction with Multiple Heats to advance any winner of a Multi-Player game, but the determination of finalists can also involve alternates in the form of best second-place finishers as required to fill out the field for ideal SE play; say 25 players for a five-player game or four players for a two-player game. A fair method of breaking ties for the last qualifying position should be announced in advance. The Swiss rounds need to adhere to a strict starting time schedule, but the SE rounds can be scheduled at the convenience of the players and/or GM (within limits). This format is highly recommended for games with a devoted following which would be disappointed by early disqualification from an SE format.
SWISS [Sw]: Any format of a pre-determined number of rounds in which players with the best records are paired against each other in every round. A fair and publicized tie-breaking system is very important. Players are free to drop out after losing a game, but the rounds continue for those willing to stay. Due to the time required, this format is recommended only for games with the most ardent following. ASL, VIP, and BKN traditionally use this system.
SINGLE ELIMINATION [SE]: Players play until they lose a game. Multi-player games may also advance the highest runner-ups in order to field the ideal number of players for the next round (i.e., five or 25 for a five-player game). The criteria for selecting the highest alternate scorers should be announced in advance. Brackets should be established from the outset rather than simply pairing winners as they finish; otherwise players can time their games to avoid playing someone.
When making brackets, you may want to consider the following:
DOUBLE ELIMINATION [DoEl]: Effectively, two Single Elimination tournaments run in tandem with a winner's and loser's bracket. Losers move to the loser's tournament to play other losers until they're eliminated by a second loss. Rarely used due to its length, it guarantees players at least two games. Best used with short, two-player games.
