Flow is an abstract two-player competitive game. To win, line up four of your pieces on the game board in a row, whether diagonally or orthogonally. Each turn, you must perform two actions in this order: Place one of your player pieces onto the game board. Push one of your player pieces, as well as every other adjacent piece in the direction you push. Because pushing a piece can also move your opponent's pieces, you can foil their plans at creating a line, but if you are not paying attention, you are just as likely to inadvertently create a line from opponent pieces and win the game for them! —description from the publisher
