Hello,
I am looking for assistance in creating the following tournament schedules for my Weekly Club Darts night:

Need schedules for each of the following situations:  
31 players - 6 boards
32 players - 6 boards
33 players - 6 boards
34 players - 6 boards
35 players - 6 boards
36 players - 7 boards
40 players - 7 boards

RULES
- All players exactly 4 games
- Rotating partners each game 
- Never partner with same player more than once
- Never play against same opposition player more than once
- Players will be ranked, so assignment of partners for player 1 should follow pattern of 1-16, 1-15, 1-14,1-13 (where possible) to minimize pairs consisting of 2 high ranked players (i.e. 1-4)
- Each game needs to be assigned a scorer (player who doesn't play that round)
- Each player only scores one game a night

Any assistance you could offer would be great - I would like to build a spreadsheet template and make it foolproof so that all members can use.

I don't have any software that will generate suitable schedules for you - in particular I have nothing that will help with your requirement to consider the ranks of the four players in each game.  Nevertheless, I have attempted to make a schedule for the first situation that you list - this is actually the easiest for me.

    Board A        Board B        Board C        Board D        Board E        Board F                 Scorers/Byes
