Test your wits with a classic board game that is fun for all ages!
While it looks deceptively simple, solving this brain-teasing puzzle will confound even the sharpest minds. Simply move the pieces around on the board until the large block on the upper left is in the lower left.
My grandpa made this game for me out of wood when I was a boy. It challenged me for hours on end. See if you have what it takes to solve Grandpa's Challenge!
