The object of the game is to place 4 of your pieces in a row, horizonally, vertically or diagonally. The pieces must be “connected”, meaning none of your opponents pieces may be between any of your 4 pieces that comprise the row. Players take turns placing pieces on the board. The board is vertical, so when you select the column in which you wish to place a piece, the piece will fall to the bottom of that column or if other pieces have been placed in the column previously it will be stacked on top of them. When 6 pieces have been placed in a column that column is full and no more pieces may be placed in that column.
When it is your turn to move, point to the column in which you wish to place your piece and click the left mouse button.
