Bad Sudoku

(Eingestellt am 27. Mai 2025, 05:27 Uhr von juggler)

Sudoku rules and common variants are often elegant, powerful, and intuitive. That got me thinking: what if, instead, they kind of just... totally sucked? Well, you'll be delighted to hear that I have accomplished exactly that! Starting with Classic, German Whisper, and Kropki variants, I'm pleased to report I've discovered small changes to each rule set that makes it frustrating, hard to scan, and just generally unpleasant to work with in every way. Enjoy!

Bad Classic

- Place the digits 1-6 once each in every 2x3 box.
- Digits may not repeat along any diagonal.

(Optional much harder 9x9 version)

Bad German Whisper

- Normal Sudoku rules apply.
- Adjacent digits on a green line differ by at least 5, unless they are the same digit.

Bad Kropki

- Normal Sudoku rules apply.
- Digits separated by a dot are either consecutive, or in a 1:2 ratio.
- I made some dots black and some white so it looks pretty.

Lösungscode: Bottom row of each puzzle (24 digits)

I loved the whisper logic. I despised (which is good i guess) the other puzzles but liked their logic as well

I really liked these, two points I actually laughed outloud. After not properly reading the rules to the first one then discovering halfway through the solve that you didn't add a diagonal constraint but that it was ONLY a diagonal constraint. Then also when you used different colors just because it looks pretty.

I agree with others here, the classic was kinda fun in a silly way, but both of the other two were genuinely fun puzzles i'd love to do more of. The GW in particular felt like in between a GW and a DW in a good way.

I had a lot of fun solving these after not sleeping much that night and a full shift work day!

The classic puzzles made me uncomfortable (probably in the intended way), but the others were just nice puzzles. I was surprised how quickly I learnt to ignore the pretty colours in the Kropki.

These were all great, but I found the bad classic puzzles delightful, including the 9x9! Thank you!

10:07, 53:34,71;53. I really enjoyed these. Got stuck in the first one until I remembered that there can't be more than one digit in every cae. Surprisingly, I didn't find these unsettling at all. To me the hardest one was kropki dots, but I don't usually enjoye them lol. I think this rule set actually made it more interesting to me. The german whispers line was really enjoyable with some amazing logic. Thank you!

I'm getting stuck hard on the German Whisper one. The Classic ones are fun, though! Honestly, the 9x9 is pretty cool, too, had to be a little creative with it.

Just another WOW. I love how you come up with such original ideas, and the way you execute it. Really nice stuff, totally satisfying.

I had fun with these but I'm not touching that 9x9 diagonal ^_^

So unique and fun! The diagonal 9x9 was really engaging and satisfying.

I really enjoyed the diagonal and German whisper puzzles, the kropki was fun to flesh out at the start but felt a bit like plodding to the finish (I think I am slower to work through puzzles than the average player so that may play a role). The diagonal stumped me for a minute until I realized all diagonals means ALL diagonals, not just the two longest. I also enjoyed the 9x9 diagonal.

Neat puzzles. Honestly not that cursed tbh.

Diagonal sudoku can be awkward to scan, but it isn't too bad once you get used to it (at least in a 6x6, the 9x9 was a bit much to be that enjoyable for me).

The german whisper variant is honestly pretty interesting, I quite liked that as an adjustment of the ruleset.

And ambiguous kropki dots can be interesting. Definitely the hardest of the set for me, but a few neat steps.

What does it say about me that I didn't find the scanning unpleasant or more difficult at all? Probably that I’m not so great at it in regular sudoku :D

4:52, 11:55, 16:38, and for the 9x9 23:02. Nice puzzle

That is stunning once again. Especially that last one is awesome. In the mix 2*. Thx.
