X-Sums and X-Products
(Published on 28. June 2023, 19:19 by RockyRoer)
There aren't enough puzzles taking advantage of products as a clue type, so here's a few I found, and one I made.
- Production Line by starwarigami
- Which is Which and Which is Which, Again by DJV - killer cages are either sums or products
- Region Sum/Product Lines by Migu
- X-Products by bigger - pure x-products
Did I miss your favorite? Suggest it below in the comments! And here's my addition to the collection:
The Rules:
- Normal sudoku rules apply
- [X-Sums/X-Products] Numbers on the outside of the grid are either the sum or product of the first X cells seen from the direction of the clue where X is the digit in the cell next to the clue. The solver must determine which clues represent sums and which ones are products.
The Puzzle:
Try it on CTC's SudokuPad:
Solution code: Row 8 from left to right (9 digits)

What? You're making us do math???!? Very nice. I don't see products a lot in Suduko and it was a nice change of pace.
