You might try Sudoku with fabric. I don't know how to set up the game, but each person brings I think 5 inch squares of fabric. One person might bring x number of red, another x number of blue, etc. Each color represents a number. When the game is finished the squares are laid out in a throw size top and the winner gets the fabric. I'm sure if you google quilt Sudoku you will be able to find how to do this. We have done this at a couple of my guild meetings and it was fun.
