Draw a line between many gawpsters of the same color to make them disappear. Bigger combinations will give you more points, but you lose a life if you touch by accident a gawpster of a different color, or if such a gawpster crosses the line you're drawing. When all gawpsters disappear, small yellow faces (little gawpsters) will be floating on the air, they'll give you extra points if you catch them. Sometimes giant gawpsters appear: you can connect them to gawpsters of any color to make them vanish. To capture a bonus, touch it with your line while you join two gawpsters of the same color.
Click on a gawpster and then keep pressed the mouse button while you move the pointer over other gawpsters of the same color. When the group disappears the place is populated with small yellow faces, click them to earn points.
