Use the mouse to mark the point of intersection or the arrow keys to move the circle pointer to the location indicated by the numbers (x,y). The first number "x" represents how far right or left; the second number "y" how high or low. Press "Hit!" (the space bar) to paint the dot. The dots will be connected automatically. When you have painted all of the dots the completed picture will display for a moment and then the next picture will start.
