Color

Another thought. What about color sudoku? I think it would look pretty cool, I have a preview picture on the facebook page (You an find that link in the about section!), but it may be overkill unless there is some sort of special occasion (like puzzle number 10, or for holidays). I think a red and green puzzle would be so cool, don't you? I guess then we might need colors for hanukkah as well though, I don't want to leave anyone out! Just a thought! Enjoy your puzzles everyone!!!
