The ladder starts play at 6 pm on Mondays and the first 25 players to show up get to play. Sign ups begin before 6:00.
Players are mostly proficient but there is room for intermediate players.
The following is an example for 16 players. The players are broken up in 4 groups (Courts). You get to play 24 games, 8 with each member of your group. The one winner of each group moves up the next week and one loser of the group moves down.
It is not a serious group as any one can join and play anytime they like. The seeding is usually done by an organizer volunteers to run it at the start of each sessio. It takes about 1 ½ hrs to complete.
It works out that the level 4 players end up playing on court one and level 3 players end up on court 4. If during the course of the season there are higher numbers than usual, e.g. 25 or more then a consideration will be made to split the group into two sessions:
