Suduko is a puzzle and the quilt is made it the order of the puzzle. There are nine squares each with the numbers 1 through 9 each set has only one number in it of each and each row across and down have only one of each numbers it is a logic game and until I started reading the book I did not know what it was. My son plays the game all the time. The qulits are quite beautiful and I think I will do one of them this summer. It will take me a little time in my budget to afford the fabrics. I like the one with x in the design. The fabrics are bright colors and they seem to match several in one of the designs in the book. I hope that helps answer some of your questions.
