Tree
(Published on 23. April 2024, 12:48 by sunnyjum)
Normal sudoku rules apply.
The cell at R4C4 contains the trunk of the tree. The sum of all digits along a branch (including all sub-branches) is that branch’s weight. The three branches connecting to the trunk each have the same weight. Additionally, every time a branch splits in two or more directions the weight of each of its sub-branches is the same.
Another way to think about it: If you were to remove any single cell from the grid (even the trunk), any branches that become isolated from the trunk will have digits totalling to the same total.
Example: R8C6 = R8C7 + R9C6 = R7C7 + R8C8 + R9C8

Excellent puzzle & concept. I did spend too long working on the wrong spot for the breakin while missing the obvious starting point, and then had to stop. Came back to it later, spotted the obvious this time, and remembering what I'd done before made it a ~15 minute solve that flowed really well.
