I have started a checkerboard and will make the game pieces by cutting out round circles (2 1/2") and fusing to double sided fusible material. I have made a Sudoku quilt a couple of years ago using African fabrics. I want to make a larger one with actual Sudoku theme fabric I purchased for the backing and random numbered squares. Patterns were available for Bacgammon and Parcheesi a few years ago for purchase. There may be others as well. Also, I have seen patterns for a crossword puzzle and puzzle pieces.
