Pasang is a two-player abstract strategy board game from Brunei.
 The game is often referred to as Pasang Emas which is actually a software implementation of the traditional board game.
 The object of this game is to acquire the most points by capturing black and white tokens on the board.
 Black tokens are worth 1 point, and white tokens are worth 2 points.
 The board is initially laid out with all 120 black and white tokens in one of over 30 traditional patterns.
 Players choose a piece called a "ka" which is used to capture the tokens on the board.
 Each player's "ka" moves around the board capturing as many tokens as possible.
 As a note, the "kas" are the only mobile pieces in the game.
 The other pieces are stationary, and are captured by the "kas".
 Players must capture token(s) during their turn, or lose the game.
 When all tokens have been captured from the board, the player with the most points is the winner.
 However, if there are any tokens left on the board, and none can be captured on a player's turn, then that player loses the game, and the other player is the winner.
