Situation - 

5 different yard games
10 Adults, 10 Children

Two random teams (1 Adult with 1 Child) play each game once

Each yard game consists of 4 players (Adult 1 + Child 1 vs. Adult 2  + Child 2)

I have an adjustment to make

16 Adults 
13-14 Children

I know that having an uneven amount of people will not allow for a balanced matchup but still hoping to get a pairing of Adult and Child with some byes.

I'd also add 2 more games (7 total stations/yard games)

The only way I see it working is if you have a multiple of 4 people (half adults and half children).  Then you can use the schedules in the downloadable Excel spreadsheet attached to this thread - you must be logged in to the forum to see the paperclip download icon.  The schedules need to be adjusted by shifting the order of the columns in each foursome, keep 'a' for adult and change 'b' to 'c' for child.  So for 20 players the converted schedule would be:

            Game 1         Game 2            Game 3          Game 4           Game 5
Round 1 (a1 c1 v a6 c6) (a5 c5 v a10 c10) (a4 c4 v a9 c9) (a3 c3 v a8 c8) (a2 c2 v a7 c7)
Round 2 (a5 c3 v a9 c7) (a4 c2 v a8 c6) (a3 c1 v a7 c10) (a2 c5 v a6 c9) (a1 c4 v a10 c8)
Round 3 (a4 c5 v a7 c8) (a3 c4 v a6 c7) (a2 c3 v a10 c6) (a1 c2 v a9 c10) (a5 c1 v a8 c9)
Round 4 (a3 c2 v a10 c9) (a2 c1 v a9 c8) (a1 c5 v a8 c7) (a5 c4 v a7 c6) (a4 c3 v a6 c10)
Round 5 (a2 c4 v a8 c10) (a1 c3 v a7 c9) (a5 c2 v a6 c8) (a4 c1 v a10 c7) (a3 c5 v a9 c6)

This is also a team competition between Team A (a1-a5 & c1-c5) and Team B (a6-a10 & c6-c10), but you could choose not to tell them.

This looks great.  I believe this should work for what we have planned.  Thanks!
