In the second part of Digging Ball 2, you will continue working on a special digging machine. On the screen in front of you, you will see a ball of a certain color lying on the earth's surface. At a certain depth underground, a special well can be seen. You must get the ball to fall into the well. To do this, use your finger to dig an underground tunnel on the screen. The ball rolling along it will fall into the well, and you will receive a certain number of points for doing so。
