OpenKropki

OpenKropki is an open-source implementation of the 'kropki' game.

'Kropki' is a pen & paper game somewhat popular in Poland (kropki), Russia
(точки) and Czech republic (židi). The game's name translates simply as
'dots'.

The concept is similar to Go, although it have been adapted for on-paper
gameplay:

* every player takes turns into putting a new dot on the field.
* when one of the player managed to put his dots all around a group of enemy
dots, he creates a 'base', capturing the enemy's dots.
* a base cannot be trespassed by the enemy, but it can get captured.
* the game ends when there is no place left on the field. the player that
captured most of enemy dots wins.
