The Kakadu is a round robin monthly event. At the end of each month the top players from each division are promoted to the next level and the bottom in each level will be demoted. The actual number promoted depends on the total number of players and divisions and is given by int((number of entries/number of divisions)/4).

Players start at the lowest level. Players may preserve their position in the ladder by notifying the host if they will be absent for a period.

As there is no time available for playoffs of tied players, several levels of tie breaking are employed to break ties to determine promotions and demotions.

Play begins on the 1st of each month until the second last day of each month. Forfeits are determined based upon scheduling emails. Please report any no shows using the scheduling form so that everything is kept on record.
