Marble rolling toy

Put a marble in the starting location shown in the first photo, and try to roll the marble into the hole at the top without allowing the marble to fall into the larger pits. You can either hold it with your bare hands, or you can place it on a ping pong paddle.

This design has several improvements over Marble Challenger 1, including:

-a base to keep marbles from falling through the bottom of the toy
-a rim around the top edge to keep marbles from falling from the edge of the toy
-a larger finishing hole to better accomodate marbles
-a reasonable difficulty level (I couldn't finish Marble Challenger 1 after about 300 tries, but I finished Marble Challenger 2 after 10 tries)
