Yes, remove the match 4 column to leave 7 rounds on 2 courts.  The removed matches can then be rearranged into 3 more rounds as follows:
( 4 5) ( 2 8 )
( 3 4) ( 7 8 )
( 2 3) ( 6 7 )
which leaves ( 5 6) to be played in an 11th round on its own.

Hi HGS,

When it says player 1 is the ghost, it means that you should take the schedule for 8 players, and then delete all the matches that involve player 1. This will leave you with a schedule that involves 7 players ( numbered from 2 to 8 ) with 3 matches per round.  In each round, the player who was scheduled to play the ghost in the original schedule, is now the player with the bye.

Hope that helps,

Ian

Copied from: https://www.devenezia.com/downloads/round-robin/rounds.php


A cyclic schedule for 7 players can be formed by using match 1 as the bye match.

Let player 1 be a ghost, and the other player in match 1 sits out the round.


I dont understand that.:(
Please can you explain it to me.

Thanks ... I'm missing the 2x reserve.

I also found this one ... I can fill it in twice ... I only have to shuffle the names in the 2nd 14 round list.

Hi Markie,

A balanced schedule is not possible here, but the closest it is possible to come to meeting you criterion of 'everyone 2x' is to have 30 rounds.  In the schedule below players 6, 9, 11 & 14 have one fewer game than all the others, but adding the match (6 11 vs 9 14) would give you everyone paired together exactly twice.

( 8 10 v 14  3)  ( 5 12 v  4 13)  (11  6 v  2  1)

Requests / Tennis season 14 players
« Last post by Markie on March 19, 2026, 12:53:42 PM »
Dear Ian,
I looking for a "tennis season list" for the following :

- 14 players.
- 3 tennis courts.
- Each player partners with everyone 2x.
- My guess is that you should play each opponent 4x.
- 2 players have to sit out each round (reserve).

I hope that you can help me.

Thanks to all the contributors and moderators of this forum!

I have found several balanced solutions in this forum and the one I chose doesn't work too well starting in round 11 (1 team in round 11 repeats from round 9, etc.).

We have 7 players that play for 2 hours on 1 court and my goals are to find a schedule for 13 rounds of play that mixes up partners and opponents "fairly" with the following goals:
1. Players pair with each other at least once, but 2 times max.
2. Players oppose each other at least twice
3. No player sits out more than 1 round
4. No player plays more than 2 games in a row
5. All players have as close to the same number of games in rounds 10-13
6. A "team" of players do not repeat playing together within at least 3 rounds

I'd appreciate any help! Thanks!

Chip

Ian,
Hello. I have continued playing these tournaments following the player distribution/allocation that you helped me with, and it has been a very positive experience.
Thanks again!
