A little bit of guessing with the remaining 1's but not bad.

Beautiful pattern, but multiple solutions. Took three attempts and worth it!
Thanks.

Had to work out the last part but was fine using temporaries and it's symmetrical so could guess ok. thank you - I enjoyed it.

Easy guessing at the end. Thanks.

Even with symmetry, there are a lot of possibilities for C6-8, C18-20. The outside two ambiguous columns are mirror images of C9-10 and C16-17.
