I'm the Grandpa, which means I'm at that age where I'm supposed to do things to keep my mind active. Problem is S works the crossword puzzle before I can get to it, and I'm not a big fan of soduku. (Of course it wouldn't matter if I was, because she works that too. However, there is a puzzle I do like. In fact, if you're good at drawing mental maps (S isn't) it's downright addictive. It's called Hidato, and you can find the puzzle daily here.
