Title: 9 Teams 8 Events but hear me out
Post by: YardGamesCo on August 04, 2025, 11:08:56 AM

I know in a previous post it says it isn't possible because a team will have a bye every round. I was thinking of the Bye team playing a cross division game vs a Bye round team from another 9 team division to fix it.

Can I still see what it would look like for 8 rounds?

Thank you

This is possible but there needs to be 9 rounds and 9 events - then each team has 8 intra-divisional games and 1 inter-divisional game and plays each event exactly once.  In the schedule below division 1 is teams A to I, and division 2 is teams J to R, all the inter-divisional games are on the main diagonal.  Because of the symmetry, rows and columns can be assigned to rounds and events either way.  Hope that helps.

(A J) (Q R) (D I) (C G) (B H) (M N) (E F) (O P) (K L)
(H I) (B K) (N Q) (L O) (P R) (E G) (C D) (J M) (A F)
(M R) (E H) (C L) (P Q) (F I) (B D) (K O) (A G) (J N)
(L P) (C F) (G H) (D M) (J K) (A I) (N R) (B E) (O Q)
(K Q) (G I) (O R) (A B) (E N) (C H) (J L) (D F) (M P)
(D E) (N P) (K M) (J R) (L Q) (F O) (A H) (C I) (B G)
(N O) (L M) (B F) (E I) (A C) (J Q) (G P) (K R) (D H)
(F G) (A D) (J P) (K N) (M O) (L R) (B I) (H Q) (C E)
(B C) (J O) (A E) (F H) (D G) (K P) (M Q) (L N) (I R)

If you look at reply #1 here (https://www.devenezia.com/round-robin/forum/index.php?topic=1240.msg3349#msg3349) from 2017, then (if you are logged in) there is a downloadable Excel file with a similar schedule to the one above, but for 14 teams in a 7x7 square.
