Lovely puzzle, 2* break in which was very fun to find. I thought that the rest of the puzzle deserves 3 stars, it was quite challenging for me to find the next digit after the break in, but I finally managed to deduce it and it was very smooth sailing from that point on! Very fun puzzle!

Excellent construction. I love how renbans polarity is constrained by thermometers and the overall symmetry. A joy to solve

Cool puzzle but also seemed so familiar! Was this in James Sinclair’s weekly puzzle set a while back maybe?

Solution code is wrong. I even tried each 9 digits from r1-r9 & c1-c9

Thanks for the heads-up. I had transposed the last two digits. Now corrected
