I found an hack way right on the begginning of the level. I just used the moveable block, push the ball stronger and that ball would fall next to the hole and press the win block.
@Tadashi Suzuki Hi. Thanks for the feedback. I tried several times and I did not win the ball. Maybe you had a lucky chance. Won the way you intended? I can fix this if it repeats itself more often. Thanks for playing.
Very fun tricky/logic level although the beginning is a bit hidden...Thanks for sharing and well done @Jóh
@Jóh - Ya I eventually seen that but dropping the balls didn't do much if anything so I gave up wondering what you may want....
