TYPES OF TOURNAMENTS

      Elimination (Single and Double)

      Round Robin

      Challenge

SINGLE ELIMINATIONThis type of tournament is used when time is limited such as on weekends, one-day events or final playoff of round robin tournament. (Sample Single Elimination Tournament)

      If the number of participants is a power of two, then no byes are necessary in the first round.  Example:  4, 8, 16, 32, 64, etc.

      Number of byes = next power of two – number of participants.  Example: If you have 5 participants, the next power of two is 8 so 8 – 5 = 3 byes.

      Number of games = number of participants – one.

DOUBLE ELIMINATION – This type of tournament is similar to the single elimination but everyone gets a second chance.  Losers of winners bracket drop down to play again in loser’s bracket.  Each participant must lose two games before being eliminated. (Sample Double Elimination Tournament)

      Minimum number of games = (2 X number of participants) – 2.  Example:  With 12 participants;  (2 X 12) – 2 = 22 minimum games.

      Maximum number of games = (2 X number of participants) – 1.  Example:  With 12 participants;  (2 X 12) – 1 = 23 maximum games.

ROUND ROBINThis type of tournament is the most popular and provides maximum playing time for participants.  It is used for league competition and is very time consuming.  It is important to first determine the number of games to be played. (Sample Round Robin Tournament)

      Number of games - (number of teams) x (number of teams – 1)
                                                                       2
                        Ex:  8 teams = 8x7 = 28 games
                                                                                                                             2

      No more than 8 teams to a section should be used because of time involved.

      Number of rounds - Even: N – 1, Odd: N

      Number of games per round – Even:  _N_     Odd:  _N - 1_
                                                                         2                       2

            Ex:  6 teams = _6_ = 3 games                        5 teams = _5 - 1_ = 2 games
                                        2                                                                  2

CHALLENGE TOURNAMENTS – Participants challenge each other.  This type of tournament can be carried on with little supervision.

      Ladder  - good for individual contests and can be self-directed. (Sample Ladder Tournament).

      Pyramid – good for large numbers of individuals and can be self-directed. (Sample Pyramid Tournament).
