Players take turns filling in hex spaces. The goal is to form a chain of their pieces to make a connection between the player's edges (North to south for player 1, and West to East for player 2). After the first move, the second player has the option to swap colours.

On Abstract Play, the default size is 13×13, and sizes 11×11, 15×15 and 19×19 are available as variants.

Connect your two opposite sides of a hexagonal rhombus. Player 1 joins the marked pair of sides; player 2 joins the other pair.

Inventors: Piet Hein, John Nash

See Wikipedia: Hex.

After your placement, if your stones form a contiguous chain (hex adjacency) between your two sides, you win. A game of Hex cannot draw on a filled board.

Empty hex rhombus, default size 13. Pie rule available.

Place one stone on an empty cell. No captures. No passing.

Sizes 11, 13 (default), 14, 15, 17, 19.
