By far one of the easiest levels, if I had to rate them. All you have to do is draw three shapes: a rectangle, a triangle, and a circle, and you have to make sure the circle falls into the pit. The best thing to do would be to make tiny rectangles and triangles on the left side of the yellow box. Then go draw a circle that will barely fit in the right side of the pit, the deepest part. Then move it barely to the left of the triangle and rectangle. That way it can build momentum to get over the hump. A very easy but boring strategy(it is probably the fastest too) is to create a small/medium circle in the top left corner of the yellow box so when you press play it will simply roll over the bump and into the pit.
