In Classic mode, your goal is to connect the orange circle to the square! Click on any tile to rotate it clockwise.

Make sure each line is used to make the connections.

In Draw mode, drag to draw a line from the 1 to the 2, going through all of the empty circles on the way.

In Tower mode, drag between 1, 2 and 3 to clear those circles. Your line must start on 1 and go up by 1 for each circle it passes through. Try to clear as many as you can before you run out of time!
