Havannah is a two-player abstract board game played on a hexagonal board that was invented by Christian Freeling in 1981. This game is a member of the connection game family including such game as CrossWay, Hex, and Y.

In 2002 Christian Freeling offered a prize of 1000 euros, available through 2012, for any computer program that could beat him in even one game of a ten-game match.

Havannah is played on a hexagonal board, 8 cells per side. Other sizes can also be used (e.g. 10 cells per side).

The goal of Havannah is to form a ring, or a bridge or a fork:

• A ring is a loop chain of player's stones around one or more cells (cells can be empty or occupied by stones of any color);
• A bridge is a chain of player's stones, connecting any two of the six corner cells of the board.
• A fork is a chain of player's stones, connecting any three edges of the board (corner cells are not considered as parts of an edge).

The draws are possible, but in practice they are extremely rare.

The game begins with an empty board.

Each player has an allocated color: White or Black.

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