You must dig a tunnel for the ball to slide straight down to the target. On the way there may be obstacles in the form of iron or wooden planks. They need to be circumvented by making turns. But keep in mind that the ball will not roll, if the surface of the corridor is horizontal, it is necessary that it goes downhill all the time.
