OpenKropki

OpenKropki is an open-source and multiplatform implementation of the 'kropki' game. It runs on most POSIX systems (Linux, BSD...) and on Windows.

Gameplay
'Kropki' is a pen & paper game that was quite popular in Poland (kropki), Russia (точки), Czechoslovakia (židi), Ukraine (крапки) and a few other eastern Europe countries. The game's name translates simply as 'dots'. The concept is similar to Go, although it had to be adapted for on-paper gameplay:


 * each player takes turns into putting a new dot on the field.
 * when a player manages to put his dots all around a group of enemy dots, he creates a 'base', capturing the enemy's dots that lie inside.
 * a base cannot be trespassed by the enemy, but it can be captured.
 * the game ends when there is no place left on the field: the player that captured the highest number of enemy dots wins.
