Hi

I have only just found this forum 

Thx for this spreadsheet

I have used it (the programming) to produce fixtures for Bowls Club Fixtures
(I can post the Spreadsheet if required)
 
I noticed with interest your reply to InnesW20

The more venues there are, the easier things get.  With 6 venues you can have:

(H A) (---) (F G) (B C) (---) (D E)
(---) (H B) (---) (F E) (D G) (A C)
(E G) (D F) (H C) (---) (A B) (---)
(---) (A E) (---) (H D) (F C) (B G)
(F B) (C G) (D A) (---) (H E) (---)
(D C) (---) (B E) (A G) (---) (H F)


how is this acheived with the Round Robin spreadsheet?

Unfortunately, the spreadsheet does not make schedules like the one above - it is called a Howell Design and is generally possible for an even number of players 2n on a square grid with s rows and s columns - where s=n is the minimum size grid (no empty cells) and s=2n-1 is the maximum size grid (this includes all possible games exactly once). I am not aware of anything that you can use to make these schedules, but you are welcome to ask me to make some for you.

Thx for the prompt response

What you are talking about is way above my pay scale but I will do a bit of research based on your recommendation

Thx again
