To complete a level, you must destroy all the bricks except for one optional category of bricks, the 10-point bricks (see the help on bricks). This mechanism of the 1-player mode pushes you to be cunning to finish the level. By using the bonus of the racket glue, the edge of your racket, the directional cross to throw the ball or the power ball, you can influence which bricks will be destroyed first (especially the 10-point bricks, therefore). For example, if there is one generic blue brick and two 10-point bricks left in a level and you destroy the generic blue brick before the level ends, you move on to the next level, thus losing the opportunity to have the points of the two remaining 10-point bricks. The difficulty in all this lies in the fact that the 10-point bricks require 8 hits to be completely destroyed. If you destroy 'all' the bricks in the level, you get a bonus of 400 points at the end of the level. You have a life counter called 'Balls in Reserve' in the top left of the information bar, but you can also have extra lives in your power bag. When the ball crosses the bottom of the screen and you have no more balls in reserve or lives in your power bag, you lose the game. If the ball is lost and you have lives left in the 'Balls in Reserve' section 'and' in your power bag, it is the counter in the power bag that is decremented first.
