I have just found out there is a more 3D Gutterball that some like better, called Gutterball 2. I like the first one best I think. One tip in this version is that the ball rolls faster and with more power if the mouse is clicked on top of the ball, and lower down it goes slower but is more able to be steered. No wonder this game has won awards. It is great. It's in my top 10.
