I may not have solved with the desired way, since more than half of the structure went unused for me.
I found this level some what slow due to the auto lift having to GO SO FAR and B having to wait for it and tapping on the auto lift was made hard due to the downward angle. I didn't like the hidden balls and based on the 1st move for B, tricks were required. R needed to walk over two balls that AGAIN DIDN'T HAVE A WEDGE TO STOP THE BALL FROM SPINNING. I also won with only dropping three balls. When you use auto pilot, be careful as auto pilot can be used against you. Here's how: Spoiler: Shortcut
@Meko Guy don't hate me I know that as usual there are no wedges under the balls, but this is still one of the first levels I had built and I still didn't know the problem, now I always put it and I'm also adding it on the old levels with 3d builder but in this I did not succeed because I was already at the maximum height limit
@Andrea gerbillo - Thanks for the video. I did it completely different. Since I don't play hidden, I wouldn't have played the level if R and Z were required inside to do something? How would I know to do that? My Z did nothing that I know of (Z stayed in the bottom walking in and out) and R won for me not Z. B got all the balls at the top. EDIT - I forgot to mention - your move with B on the side way stairs was nice but I didn't see that move nor knew about it. If you would have given a trick list then I may have learnt something new while playing instead of after. I got B to that ball by auto piloting onto R and R raised B. Mine was a lot harder but I got it easily.
@Meko Guy you were good at finding an alternative solution, I tried several times but I never succeeded
@Andrea gerbillo - I still don't know why the one ball falls, the one closest to the win - too bad you used hidden. Most times it falls as soon as the mechanism starts up. BTW, in the video, you'll see the draggable at the top had not fallen yet so B got the ball much easier otherwise it would have taken three or four up/downs to get in and out. Spoiler: My Way
@Andrea gerbillo - Again - too bad it's hidden as I'm a player that can only win what he sees and sometimes I can't see what is right there in plain sight. Glad you liked my way.
I liked this puzzle very much, even though it took me much time to figure out the effect of the various moves. My solution was more or less the same as in @meko Guy’s video. The difference is that Z (not B) pushed the high ball.
WOW!! Seeing your movie I recognize that your intended way is really clever...my fifth star is for this reason...but I won with R using a different path ...Anyway,challenging enjoyable level,thanks for sharing @Andrea gerbillo
