Surakarta is named for the town of Surakarta in Java, Indonesia. This game is also known as Roundabouts.
The game is played on a board that consists of a 6 x 6 grid of 36 points shown in Figure 1. There are also eight circular loops that extend out from the board. The points second from each corner are connected by a circular loop and the points third from each corner are connected by a larger circular loop concentric with the first.
Each player starts with 12 pieces arranged as shown in Figure 1. They are usually stones and shells although black and white pieces may be used. The object of the game is to capture all your opponent’s pieces.
To start the game, each player throws a single die to determine the player to go first. If the same numbers are thrown, then both players throw again until they throw different numbers. The player throwing the higher number starts.
The players take turns to move one piece at a time orthogonally or diagonally in any direction to any adjacent empty point as shown in Figure 2. A piece may not jump over another piece or land on another piece except in a capturing move.
To capture, a piece is moved orthogonally along a line over any number of unoccupied points including a circular loop until an opponent’s piece is reached as shown in Figure 3. The attacking piece takes its place and the captured piece is removed from the board. To capture, a piece must be moved along at least one circular loop and may be moved along more than one circular loop.
The winner is the first player to capture all his opponent’s pieces.
