Crossway  is played on a Go board (19x19).  The left and right edges are colored white while the top and bottom edges are colored black:

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.

The game begins with an empty board.

Each player has an allocated color: Black or White.

Starting with Black, players take turns placing a stone of their color on any empty intersection of the board.

Since the first player has a distinct advantage, the pie rule is used for making the game fair.  This rule allows the second player to switch colors after the first player makes his first move.

A player must never complete either of the following formations:
