Fixture Generator

I'm looking for a Macro/Algorithm/anything? to take a set of fixtures and create a round robin draw for varying numbers of teams and rounds.

The idea is for it to take each game and put it into a round so that each team only appears once in that round.
ie it starts with a list of games -
1v2,1v3,1v4, 2v3,2v4, 3v4

It sorts them (randomly?) into
Round 1 1v2, 3v4
Round 2 1v4, 2v3
Round 3 1v3, 2v4

It doesn't need to create each game as we alrady have something for that.
What we want to be able to do is take an uncompleted competition draw and recreate the draw less the games that have been played.

Hi Team,

I'm still looking for a solution to this problem. My previous query probably showed the problem too simply so I'll have another go.

What I'm trying to solve is this -

I have X number of teams in a round robin format league.

A few rounds are played and then changes are made to the structure so teams may be removed or teams may be added.

This means we'll need to regenerate the fixtures and rounds taking into account games that have been played and new games created and added to the league.
To do this manually I take all teams now in the grade and generate a new set of fixtures.

I remove any games that have already been played and show them as completed rounds.

I then re-sort the remaining games into each round where each team appears once per round.

Any games that can not fit into a round are grouped together at the end.

Any ideas?
