Connect 4

Instructions:
You are red. Move your mouse around the playing field and watch the red arrow move across the top of the screen. Then, click the mouse to place your game piece into that column. Your opponent (the computer) is green and will place its game piece in a column of its choice. To win the game, you must connect 4 of your pieces together in a row, either horizontally, vertically or diagonally. But beware, the computer is trying to do the same and will show no mercy. Make sure you keep an eye on the white box below the playing field, which will show useful information during gameplay.
