The object of Tracer is simple: trace the path on the screen. To start your trace, click on the 'S' and drag along the path until you reach the 'F'. If you release your mouse, you will have to start the level over. If you go outside the lines, you will lose 2 points and will have to start the level over. Once you finish a level by tracing your way to the 'F', you will be awarded 10 bonus seconds. Try to trace the paths as fast as possible because your score is based on how fast you complete each level. The game is over when your time runs out. There are a total of 15 levels.
