Killer Sudoku - Sums or Products
(Published on 2. November 2020, 20:26 by udukos)
Normal sudoku rules apply.
An area surrounded by a dashed line will be called a cage. Digits may not repeat within a cage. A number in the top left corner of a cage indicates either the sum or the product of all the digits in that cage.
For eg. A two celled 8 cage could be either a sum of 17, 26 or 35 or a product of 18 or 24.
Note the inequality sign in the grid.
Good luck. Have fun.

F-puzzles link has a two celled thermo in place of the inequality sign.
Solution code: Row 2 Row 3

Thanks a lot for this beauty, full of interesting steps! I solved it already in 2023, before I paused SVS. Recently I finally made my own puzzle with this ruleset. It will appear today as SVS #417, so I found it appropriate to finally enter the code. :)

" I tried to keep the logical path narrow but still fun to solve": I'd say you nailed both of those. I was impressed at (and enjoyed) the evenness of the difficulty throughout.

@PixelPlucker I tried to keep the logical path narrow but still fun to solve.
@Alexander Rappa Thank you for the nice feedback. Glad you liked it.

Loved it. Seemed like a very narrow solving path and was fun to find it.
