Quadrature is a new two player strategy game made by Mark Steere.
There are two ways to win in Quadrature: kill enough enemy checkers "squaring" them
or get three of your stones onto the enemy "Startseite plate".
To "square" an enemy checker, you move to form a rectangle
on the Bord with three of your checkers and one enemy checker.
Quadrature won the American MENSA award.
