Another version of Ping pong (Some of you call it Pong). The same rules. Don't let the ball touch the lines (Top and bottom). If you touch it, you lose. Hit the paddles (Green things) to score a point. Score 50 to win.
Sometimes there's lag, where you have to press the green flag more than once to play again. When you win (Score 50), there's lag so you must press the green flag more than once, so yeah...
