The outer box has minor signs of wear--normal for its age; the board has been taped together to make it easier to manage; from smoke-free, bug-free home

Main object: Try to connect your borders with an uninterrupted chain of linked pegs - and block your rival's attempts to stop you! 
TWiXT is for all ages - two players, or four players in teams of two.

Everything fits neatly together in the bookcase box, which measures approx. 11.75" x 8.5" x 2.25"
