Havannah is a connection game created by Christian Freeling. It can be played on many game sites, including Little Golem and igGameCenter.

How to play

The game is played on a hexagonal board of hexagons. The base-8 and base-10 boards are popular sizes. The base-8 looks like this (the area between the lines of stars):

 

The players are identified by two different colors, such as Black and White. On Black's turn, he or she places a black piece on an empty cell; White does the same with a white piece. The goal of the game is to be the first player to make a chain that forms one of these winning patterns:

  • a fork: a connected chain that has pieces on three edges of the board (where corner cells do not belong to any edge)
  • a bridge: a connected chain that has pieces on two corner cells
  • a ring: a connected chain that has at least one cell (empty or not) on its interior

Draws are possible but very rare.

On Little Golem, Havannah on base-8 and smaller boards is played with the swap rule.

(#1009271 Pascal Huybers vs. Carroll, the first board)

Solved board sizes

Size 1 and 2:

  • first player wins

Solution for size 3:

  • first move in corner wins
  • other first moves lose

Size 4:

  • is much more difficult than size 3 and not known yet
  • probably most first moves are winning (i.e. should be swapped), however e.g. first move on an edge is not clear
