Sums are products sudoku #3
(Published on 29. July 2025, 02:03 by Nylimb)
Normal sudoku rules apply: Fill the grid with digits from 1 to 9, so that every row, column, and 3x3 box contains each of the 9 digits exactly once.
Dotted lines define some cages within the grid. Digits may not repeat within a cage. Whenever two cages share an edge, the sum of the digits in one of the cages equals the product of the digits in the other. For example, a cage containing 1, 3, and 6 might share an edge with one containing 2 and 5, since 1+3+6 = 2*5. Cages which meet only at a corner are not restricted in this way.
I think this is slightly harder than Sums are products sudoku #1. (But I thought that about Sums are products sudoku #2, and it's only been solved 3 times so far, so my difficulty estimates are probably worthless.)
Solution code: Row 9.
