Click anywhere you want to make a line, making sure at least one side will not be hit by a ball. Before the line touches, use the "Level skip" code and the percentage will be higher than 100% after the line connects. Note: You won't get full score for this -- only regular scoring will occur.
After isolating one ball into a box, bring the ball down to all but one free square. Aim your pointer so that you go into the square. You will see a permanent red or blue (depending on direction) square. You can then only use the red or blue line. Keep using it slowly and get rid of as much space as possible. You will never win until you have 75 percent completed and have lost all your lives. When you are down to one ball isolated and not completed, bring it down to two lines of space and make it as little as desired. However, make sure you can still hit the ball so that you lose. You will then win and have plenty of points.
