Hello! Loved the puzzle.
There seems to be a small issue in the 7th box though - between r8c2 and r9c2, I think it should be a K instead of B!

Amazing puzzle. I initially misinterpreted the rules as groups of orthogonally adjacent cells must sum to the same number. Spent nearly an hour and got nowhere and close to contradictions. Then I noticed the rule set clearly says "pairs of adjacent ..."!
