Hit the "I" ball at such an angle that it creates a chain reaction which ultimately dislodges the "Q" ball.

Whenever the ball in motion hits a stationary ball, the ball in motion replaces the stationary ball in the word, thus forming a new word. The stationary ball is then set in motion at an angle of your choosing.

The balls always move in straight lines, never curves or arcs.

You may use the bumpers to deflect the trajectory of the ball in motion. But don't worry too much about the physics of it.

Words should be common and well-known, not obscure.
