Secret 02

@mastersifu to drop B and trigger sensor. no problem if you want to see the inside.

Fantastic outcome. I'd managed to complete the puzzle. Just when I thought I had to restart, the door opened after 20 seconds. Very nice idea.

@mastersifu Thank you for playing

I'm surprised the necessary mechanics fit in a box that small!

@MekaSage Thank you for playing.
I don't know how many times I changed the position of the puzzle holes, balls, sensors and door mechanisms. I tried my best, but there were still problems, loud noises and stuck doors.

As in the Arabian fairy tale: "Open, sesame!". The door opened for me on the second attemption.

@Helena Thank you for playing.
I didn't notice. I think it's included in 1001 nights right?

@Labyrenight, yes. This is out of 1001 nights. Your B is like Ali Baba in the treasure cave.
