I am having a 10 person euchre party, 2 tables, 2 people on bye each round, I was just wondering if anyone had a schedule I could use.  I have been trying and trying to figure it out, to no avail.  Thanks in advance!

I think there are two possible choices, either you must play 5 rounds of Euchre or 10 rounds - any other number between 1 and 14 rounds will lead to an unbalanced schedule where not all players get the same number of games, something that will no doubt lead to complaints.

For 5 rounds I think the following schedule is reasonable, the 5 pairs of players who have bye together never sit at the same table together.


( 7  6 v  2  8) (3  4 v 10  5) ( 1  9) 
( 8  7 v  3  9) (4  5 v  6  1) ( 2 10)
( 9  8 v  4 10) (5  1 v  7  2) ( 3  6)
(10  9 v  5  6) (1  2 v  8  3) ( 4  7)
( 6 10 v  1  7) (2  3 v  9  4) ( 5  8)


For 10 rounds it is possible to arrange that all 8 partners that a player has are different and that everyone sits together at a table (either as partner or opponent) either 2 or three times.

( 1  4 v  7  3) ( 5  6 v  8 10) ( 2  9)
( 2  5 v  8  4) ( 6  7 v  9  1) ( 3 10)
( 3  6 v  9  5) ( 7  8 v 10  2) ( 4  1)
( 4  7 v 10  6) ( 8  9 v  1  3) ( 5  2)
( 5  8 v  1  7) ( 9 10 v  2  4) ( 6  3)
( 6  9 v  2  8) (10  1 v  3  5) ( 7  4)
( 7 10 v  3  9) ( 1  2 v  4  6) ( 8  5)
( 8  1 v  4 10) ( 2  3 v  5  7) ( 9  6)
( 9  2 v  5  1) ( 3  4 v  6  8) (10  7)
(10  3 v  6  2) ( 4  5 v  7  9) ( 1  8)
