When a level is completed, the ball falls into one of the five bonus slots at the bottom, which are usually worth 10,000, 50,000 or 100,000 points. However, if you clear all pegs in the level all of the slots will be worth 100,000 points. You will also get other bonuses, such as the "Cool Clear" bonus and 10,000 points for every ball not used. The extra points are counted towards your Fever Bonus, which is then added to your total score for the level. Note: To get a higher Fever Bonus, save a green peg for your last shot to clear the board.
