Here's another addictive web game... what's different about it is that two players on the same computer can play it. Play for a while and then you will also get the hang of spinning the ball... then the fun level doubles! Bewarned... it can kill lots of time.
One player controls the pad with 'W' and 'S' , the other controls it with Up key and Down key.
And also, for the single player mode, the high scores are stored online.
