there was this game I played on paper while waiting in line for my wii. You made a 5 x 5 box, and began throwing consecutive numbers in (1-25) the spots. BUT. You had to go to the third box when moving in up, down, left, or right, or to the second box when moving diagnally. Pretty tough. I got a 24 or 25 that first night I played.
I also enjoy a good game of CHINA!
this sounds similar to soduko (sp?)
