I have found eight other logical solutions before solving it - or better guessing it. Quite a lot for such a small hanjie... Nevereheless, thanks for an amusement.

Can anyone give some starter hints?

Another tough one...

Hints:

It is symmetrical along the diagonal axis. The bottom left, and upper right corners are filled in with 2x2 blocks. The center 2x2 blocks are not filled in. Surrounding the white center 2x2 block are some right-angle shapes. They point to the upper left, and to the bottom right.

Hope that helped.

Too many options :-( had to read the hint after having found 2 other possible correct solutions that were "wrong".

Thanks. Those hints were perfect. I don't know how anyone could solve this without them.
