Connect Four II © 1980 Fabris, Robert.
A grid is placed on the screen. Use your Joystick to move the marker over the column that you wish to enter. Press the Trigger and the piece will go down the column as far as it can. Getting four of your pieces in a row before the computer does so will win the game. Move the Joystick back and forth to register the win.
