5 balls is enough

...
very clever mechanism
to divide ball to fill every hole.
we need to put B at two spots.

I dont have problem with hidden
parts, the differencies in lenght
when pulling the side slider is
how you manage to divide the ball..


very innovative for new member.

@Ray Aznable thank you!

I gave your level a go and gave up with the hidden. I like that you used B but too bad one needed to guess at the ball placement. Do I flick the ball, just let it fall or hold the draggable so the ball slides or let the ball fall and then push? Too many options and since I don't play hidden I had enough.

I did it with 1, one! ball, the closest to the win, then a TOA off the platform into the channel and then short walk to win.

@Meko Guy : I hope it will help.

Spoiler:
try to pull out side slider and let the ball goes. Then push in one. If the ball doesn't reach the hole then push it on again.

@András - Thanks for the hint but I decided a long time ago to just skip the hidden levels. Back then, some authors were hiding auto pilot (redirection) moves etc making it almost impossible to figure out what they might have done. My point is after spending an hour, you still may not figure it out....
