To begin the game press the green flag. You are the paddle on the left (green) and the other player is the right paddle (blue). Use the mouse to move the paddle up and down, and don't let the ball go past you. There is a total of 5 levels. The first 4 will require 25 points each to complete, and the last level is impossible, so just try to score as many points as possible. Each level is harder than the last.
