This is called 'Skeeball'. The objective is to roll a ball into this lane to make it fall into the holes at the end of the lane, where you will find the wall is slanted and with circular barriers to direct the ball if you don't hit the hole. There's a bump right before the wall so the ball jumps. The smaller and higher holes give more points.

In other words, calculating the direction and how strong you must throw the ball is key to get a good score.
