No tricks required . Have fun!

Super! Very interesting and smart classic puzzle .
Thank you

Clever mechanism with all the paths. Not sure if there's only one gameplay as it was hard to remember the correct permutations.

I think graph theory can tell a lot about this puzzle. The paths create all sorts of islands of connected paths in solution space, with the islands being only connected through obscure and 'behind the scenes' connections that one has to create using the balls.

Superb logic level where is very easy to get lost. In fact & after pushing all the balls I spents about 15 minutes trying to find the way to the win .The design looks very nice too. Thanks @P_simorf well done!

Excellent!
