Order and Chaos invented by Stephen Sniderman is a variant of Tic Tac Toe which is played on a 6x6 board. The game is played by two opponents who can place either X or O on any empty square. The first opponent is called "Order" who aims to create five-in-a-row of either Xs or Os vertically, horizontally, or diagonally. The second opponent is called "Chaos" who aims to stop first player from creating five-in-a-row and fill the board which would be a win for "Chaos". "Chaos" will also win if no five-in-a-row sequence is possible at any stage in the game.

Game starts with empty board and players take turn to place any of the two pieces (X or O) on the board. "Order" starts first. Once played, pieces can not be moved.

Play Instructions: Select a piece and then click target square to place it there.
