A game of connecting opposite sides of the board, but lines of pieces may not cross each other.
Crossway is a played with a Go set. The board starts out empty. Each player takes possession of all of the stones of one color. Draws and ties cannot occur in Crossway.
Players take turns adding their stones to the board, one stone per turn, starting with Black. A player must never complete a 2×2 formation with two diagonally adjacent stones of each color.
Passing is not allowed, but, if you have no placements available, your turn is skipped.
To ensure fairness, White will have the option, on their first turn only, to swap sides with Black instead of making a regular move.
For White to win, White must form a contiguous sequence of white stones connecting the West edge to the East edge of the board. Each stone in the sequence must be connected to neighboring stones in the sequence via horizontal, vertical, or diagonal adjacencies. Likewise for Black and the North and South edges. A corner is considered to be part of both adjoining edges.
