This is a Pong game. You must earn as many points as possible before your computer opponent scores. This is fairly easy, and the challenge lies in a leaderboard that lists the all-time best, second place, and third place scores from all players. Control using the mouse. If you wish to play again after a fail, you need to reload the page or click the green flag twice. Press Q to force a game over and test your position on the leaderboards.
Thanks to MrTorr for providing the basic mechanics. Note: Unfortunately, you will not be able to access or change the leaderboard unless you have attained the Scratcher status.
