The Hex is traditionally played on a 11x11 rhombus board, as Piet Hein suggested. Other sizes such as 13x13, 14x14 (advised by John Nash as an optimal size), 15x15 or 19x19 are common. Pairs of the opposite board edges are marked with two colors, usually Red and Blue.

A game begins with an empty board.

Each player has an allocated color, usually Red and Blue.

Players take turns placing a stone of their color on any empty cell of the board.

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

The game ends up when one of the players forms a connected chain of his stones linking two opposite board edges marked with his color.

No draws are possible in Hex.
