Query: Right-Brained Sudoku is a Winner!

Super logic game for all ages - Grandpa, dad, and grandson all just love it -- you can play solo or duet (take turns trying to make a play).Good antidote for kids who are glued to their gameboy. It's sudoku for both left and right-brained folks -- numbers are good for left-brainers, but the colors are better for others.
