Title: Euchre 24 players, 12 rounds
Post by: kimpurely on January 17, 2008, 06:07:07 PM

I am looking for the best way to set up a 12 round tournament with 24 players. I don't want anyone to be partnered with someone more than once, and I want everyone to play at the same table atleast once (I know with 12 games not everyone will be able to partner together, but atleast everyone can play at same table will all 24 people). Does anyone have any ideas on how I can set this up? Thanks.

I think the schedule below will work for you.

(A U v J S) (B W v E M) (C V v H P) (D X v K R) (F O v I Q) (G N v L T)
(A X v F N) (B V v I T) (C W v L Q) (D U v G O) (E P v J R) (H M v K S)
(A W v G T) (B M v L R) (C P v I S) (D V v F Q) (E O v K X) (H N v J U)
(A N v K Q) (B X v H S) (C U v E R) (D O v J T) (F P v L W) (G M v I V)
(A P v H X) (B O v G W) (C N v F V) (D M v E U) (I R v L S) (J Q v K T)
(A S v E V) (B T v F U) (C Q v G X) (D R v H W) (I P v K N) (J O v L M)
(A V v D W) (B U v C X) (E T v L P) (F S v K O) (G R v J N) (H Q v I M)
(A T v C R) (B S v D Q) (E W v I N) (F X v J M) (G U v K P) (H V v L O)
(A Q v L U) (B R v K V) (C S v J W) (D T v I X) (E N v H O) (F M v G P)
(A R v I O) (B Q v J P) (C T v K M) (D S v L N) (E X v G V) (F W v H U)
(A O v B P) (C M v D N) (E S v F T) (G Q v H R) (I W v J X) (K U v L V)
(A B v M N) (C D v O P) (E F v Q R) (G H v S T) (I J v U V) (K L v W X)

Everyone should have 12 different partners and oppose all other players at least once.

I love that schedule. I'll use it for our next euchre party. Unfortunately, tonight's party had a group cancel, so we have 20 people. I don't know how to change the schedule to fit 20. When we have 24 people, I will use that schedule for sure. Thank you!

Kim,

A similar schedule is possible with 20 players, however it is not quite as nice since groups of 4 players meet together twice on the last table (see rounds 1&6, 2&7 etc...)

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