Thanks! this one helped

@Miguelh1020 Felt so too, tried to make an optimized version for a full 16/s belt and found out that it seems to make shapes big or small DEPENDING ON ORIENTATION!! My stackers had the input coming from above, and this has the input coming from the right. Changed it around and it's working!

I worked for quite some time with this shape. I just can't quite understand te rules. Sometimes the shapes get bigger when I don't want to, and sometimes it seems they should get bigger but they don't. Maybe I am unintelligent??

thanks. It really works

I don't understand why the 2nd to last stacker treats the top right shape different from the other 3

nonsense

Thank you. This also helped me figure out the logic in level 25. The stacking works so strangely with the pieces going up in size suddenly after cutting. I wasn't going to do this for the upgrades, so imagine my surprise when it popped up for level 26.

you good man

I thought I was so close! I was making the design with layered junk quadrants and got the right-half to work while keeping the layers in order. Then I discovered the game has an illogical rule that, if you have any layers that can be increased in size again in equal steps.. it will! I made the left-hand side and was screaming "Why?!" when it kept changing size after getting the pieces down to the 3rd layer and cutting away the junk segments I used to force the layering.

Thanx
