1. There will be 4 extra ping-pong balls (2 red and 2 blacks) on the playing field.
2. The robot's mission is to push the BLACK ping-pong balls off the holder, and make sure the RED ping-pong balls remain on the ball holder at the end of the game.
3. Each BLACK ping-pong ball pushed off the ball holder = 10 points.
4. Each RED ping-pong ball that remains on the ball holder = 10 points.
