|Object of the Game
The goal of Crossway is to form a chain of your stones connected either horizontally, vertically or diagonally linking the opposite edges of the board marked by your color. I.e. White should connect the West and East edges and Black should connect the North and South edges. A corner is considered to be part of both adjoining edges.
No draws are possible in Crossway.

A player must never complete either of the following formations:
