|Surakarta is a two-player board game that is called "a little-known Indonesian game" in many articles (including Wikipedia). However, there is no any strict evidence of the existence of such a game in Indonesia and it seems that the only relation between the game and Indonesia is in that the game was named after the ancient city of Surakarta in central Java.
Surakarta is played on a special board with the grid of 6x6 holes. Some of the edge holes are connected with special circular "circuits" used for capturing opponent's stones (see below).
There are two players using stones of two different colors.
The initial position of the stones is shown in the following picture:
The objective of Surakarta is to capture all opponent's stones.
