Sums and Products Killer Sudoku
(Eingestellt am 29. November 2020, 04:46 Uhr von PixelPlucker)
This puzzle is a variant killer sudoku, loosely based on Qodec's Product Killer and udukos' Sums or Products. This time, it's sums and products!
- Normal sudoku rules apply.
- Digits in cages may not repeat and must sum to the total indicated (or, if a range is indicated, a total within that range). Some cages may have unknown totals.
- An X between cells indicates that the two adjacent digits are multiplied when calculating the cage total.
For example, the total of the 49-cage would be calculated like this:
49 = (R7C1 x R8C1) + (R8C2 x R9C2) + R7C2 + R9C1
You can play this puzzle online using f-puzzles or Penpa+. Enjoy!
Lösungscode: Column 5, column 6 (18 digits without spaces)

If people don't particularly like arithmetic, they should do this puzzle. It is so cool in its geometric ideas that you forget all the calculations you thought you might have to do. Splendid puzzle with an unexpected break-in and some marvelous moments along the way.

Haha, I can totally related to RockyRoer's comment. I was staring at this for like five to ten minutes, thinking this will be a super annoying pencil mark battle, but their comment kept me motivated. Once I focused on a strategy and quickly found the entry, it was a very smooth solve that was super enjoyable. Thank you!

Loved it -- i couldn't believe that it would be solvable with all the possibilities with multiplications - yet it slowly and surely came together. And that worthless >20 clue!
**Haha, that's great to hear! Glad you enjoyed, Rocky :)
