Free games

My 6 year old loves this game.  He got past all the tutorial section, and enjoys playing it.  It is very good for kids because it teaches them to think a few steps ahead, like chess.  But it's fun..  and challenging.  I find myself trying several levels over and over agian.

It's free from microsoft.  You have to sign up for the microsoft live.... But they provide a pass code on the tinker site.
