Stingy Cages
(Published on 10. July 2024, 14:22 by sujoyku)
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Killer cages: Digits in a cage must sum to the clue in the top left.
- Stingy Condition: Any two killer cages can have at most one digit in common. For example, if a cage contains the digits 1 and 2, no other cage may have both these digits.
Here you can solve the puzzle online:
Solution code: Row 3 from left to right (9 digits in total)

You are much welcome, Meech, thank you for commenting! I am glad that you enjoyed solving the puzzle. To my knowledge, it was the first one with this exact ruleset. I have set one more puzzle with the Stingy Cages constraint which is in testing at the moment.

Took me ages until I obeyed the rules. Then I thought: you always create such beautiful puzzles, I must do something wrong. And alas, when I started to really ponder the rules, it was easy with a nice flow. Thanks for sharing!

Thank you for your kind comment, nunc! I am glad you liked the puzzle and I hope that first phase did not cause you too much headache.

Very nice puzzle! I thought it was a bit closer to 2* difficulty than 1.

Wow! That was quite fun! I was worried when I read the rules it wouldn't be that nice and straight forward, but was I wrong! That was a beautiful puzzle with a great new idea. Well done!
**
Thank you for your comment, meggen033! Great to hear you had a fun solve. Yesterday, I have set another slightly tougher puzzle in this variant (not yet in testing), but probably one needs to be careful to not sacrifice smoothness for difficulty.

Very fun variation of the killer rule. When I first read the rules, I expected this to require quite a lot of bookkeeping but the way the cage totals and cage sizes where chosen, every deduction felt very natural and smooth. Well done!
**
Thank you for your comment, gdc! I am glad that you liked the puzzle. Also it is great to hear that you found it not to be requiring a lot of book-keeping. I wanted to keep it reasonably approachable. Probably, one could use the ruleset for harder puzzles, but one had to be careful that it does not get tedious in the way you described. Thanks again for sharing your thoughts.
