High completion percentage
Click anywhere you want to make a line, but be 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 will not get full score for this -- only regular scoring will occur.
Get as close to perfect as possible every time
Isolate one ball into a box, then 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 now 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 a lot of points.
