Tennis ladder and box league generator

Challenge players two or three places above you. Pyramid ladders let you challenge anyone in the row above.

The match is played within 7 to 14 days. Agree a date within a few days of the challenge.

A winning challenger takes the place and everyone in between moves down one. If the challenger loses, the order stays. Some clubs drop the loser one place instead.

Refusing a challenge without a reason, or not turning up after 15 minutes, counts as a loss.

The challenger books the court and brings a new can of balls.

The same two players meet again only after a waiting period, often one to eight weeks, so one pair cannot block the ladder.

New players start at the bottom or challenge their way in. Players who do not play for about four weeks drop a few places.

Players of similar level form boxes of four to six. Box 1 holds the strongest players.

Everyone plays everyone in the box once within the period, usually six to eight weeks.

Common schemes: 3 for a win and 1 for a loss, or 1 point per game won plus 2 for the win. Some clubs give 5 or 4 for a win and 2 or 1 for a loss, depending on sets. The per-game scheme works best when every match has the same number of games, for example 15 straight games or one pro set.

The top two move up a box and the bottom two move down. Players with fewer than two matches cannot move up.

Refusing two dates, arriving more than 15 minutes late or cancelling less than 24 hours before gives the match to the opponent.

Each club sets its own order. Most common: head-to-head first (or the matches among all tied players), then sets and games won. This generator puts wins first with 3/1 points, so nobody climbs just by losing more matches; with per-game points, more matches played counts after the head-to-head.
