I can't find anything in the search. This is supposed to an easy game. If so, I'm in trouble. I was doing fine til I got to this one. I'm having a difficult time beginning. I am not sure which one is supposed to be the base. I am thinking the couples, but not sure. Thanks

Write nine slots at the base, three for each dance. This game is easy if you can catch the big inference stemming from the r2 = s3 rule. Because no pair can repeat, it means that the boy from these two pairs must be with t in the first dance. You can then frame the game along the KS rule and it becomes a very limited diagram.

The game I have is about the couples going to dinner. John & Kate, Lewis & Marie and Nate & Olive.
