My solution is easier,I mean.... Spoiler https://photos.app.goo.gl/gF5y2HhVMBP3SBKC9 Thanks for sharing @EL797
@delator77 Yes but it doesn't work all the time. Spoiler Sometimes Z will fall onto the ground, so I didn't use that solution.
@EL797 You're absolutely right but it worked for me on the first try and ... but then I tried more times and yes, B can fall to the ground ... It's a matter of subtlety jajaja
@EL797 - Too bad your levels are not more stable as the ball rolled out ever time. The right turn action from Z starts the ball falling towards the right and a slight bump on the pillar starts the ball rolling the other way. A simple wedge would have fixed that once again.
I won without any use of Z. B can drop the ball all alone and reach the win. I can see the intended solution, but my motivation to do so tends to be around zero..
