Thank You.

I wasn't getting anywhere at the beginning... so I took the lazy route and just centered the 11's. After that, everything fell into place. Good image at the end. Thanks.

Thanks to Rawr! I didn't find a way to really start until I read your comment, after that it was easy enough.

Is there a logical way to solve this?

Thanks.

One unique solution. Can be solved with or without assuming symmetry. Thank you for the puzzle.
