The game is played on a rectangular board   which is visualised as standing upright on one of its edges.  The board has m columns with n squares each. Two players, red and blue, take turns choosing a column and letting a counter of their color drop down to the next available space in that column. The player who is first to complete a  connected line of four counters of his colour vertically, horizontally or diagonally wins the game. 

Controls:
