Tuesday morning found Dinoguy reading some of the Viking books we checked out of the library and asking to play hnefatafl, (King's table) an ancient Scandinavian board game that was a favorite of the Vikings.
He and his dad decided that a spare piece of insulation board would make a great board and then we picked out some legos for the soldiers and king.
So we're happily playing hnefatafl here as well as chess. You can try it out online here if you don't feel like making your own board. :D
