Rendju is a game for two players: one plays with black chips (stones) and other player with white chips (stones). The playing field is the squared board either 15x15 or 19x19. The players alternate moves. Black moves first. With each move the player puts out one stone of his color on the board (at the interception of the lines). The winner is the player who creates an uninterrupted row of stones of his/her own color. This can be done horizontally, vertically or diagonally. The game continues until one player wins, until the tie, or until the moment when the whole board is occupied by stones (in this case it is also a tie). So, enjoy the game!
