Settlers of Catan is allot of fun, I don't know how educational but allot of fun as long as my brother isn't playing.

My little brother (the one with ADHD) actually loved Chess for quite awhile, got really into it!

Monopoly is still a great game! However it has been banned in my family's home because of fighting laugh.

I remember playing labyrinth when I was very young but I think the pieces were spread out over the house.
