My DS6 loves sudoku :-) His hobbies are rocket building, coin collecting (since age 4), Kcab...your child and my guy would get along great...he also collects maps (mostly train and subway line maps) and has routes memorized for the Acela, Empire Builder, Sunset Limited, TGV,....the list goes on.
When guests come over, they look at us a little strange when they see his room - the wall is covered with the periodic table, titanic artwork (loves the titanic), and all things storm/tornado chasing - including his coveted autograph from Reed Timmer from Storm Chasers ....not the typical 6 year old!
