Experimental Puzzle 6/6: All Rules Combined
(Eingestellt am 18. Mai 2026, 20:40 Uhr von Sudokujoker)
This is the final puzzle in my series of experimental puzzles. This combines all constraints from the previous five puzzles in one 9x9 sudoku.
Normal sudoku rules apply: place the digits 1-9 in each row, column and 3x3 box. Dynamic fog: the grid is covered in fog. Correctly entering a digit will clear the fog in that cell and may clear the fog in other cells too. Anti-knight: digits within a chess knight's move cannot be the same. Anti-king: diagonally adjacent digits cannot be the same. XV sums: a pair of digits joined by an X sum to 10 and a pair of digits joined by a V sum to 5. All possible XV symbols are given. Thermo: digits along a grey thermometer increase starting from the bulb. Kropki: Digits joined by a black dot are in a 1:2 ratio. Digits joined by a white dot are consecutive. Not all possible dots are necessarily given.

Excellent work.

Thanks, well spotted! Rules now updated to say "1-9" rather than "1-6" :)

with the flood of comments about "posting etiquette", not one person noticed that the rules should say "1-9" etc.

Took me just short of three hours, but i got there! Really nice rollup of all the previous rule sets

Is there anywhere an explanation on how to solve this puzzle?

I'm not sure on the lmd etiquette but I agree with Martina. I find having all the puzzles available at once quite satisfying.

It has never been recommended to post once a day, on the contrary. At the beginning of the "flooding", it has been recommended NOT to publish daily ... nevertheless ...

I don't agree with the other solvers. I appreciated them being posted like this because the intent was clear from the onset and it was easy to keep track of where I had progressed to.

Pretty decent. Winds up being kinda formulaic around halfway in, but it was fun to fill out regardless.
And yeah, as isajo4002 said, six is quite a lot of puzzles to dump at once. If you do something like this again, especially with similar difficulties, it might be better to group all the individual-rule puzzles into one submission (with a solution code like r1c1 of each puzzle, or something), and then have the "exam" puzzle as a second, separate submission.

That was pretty fun, but I think the difficulty is closer to 1 or 2*

Might I suggest not flooding lmd with puzzles. It makes it harder to see all the new puzzles when this sort of thing happens. It is recommended to post once per day. Thank you

Reply: Thank you for the feedback - I apologise for posting multiple puzzles at once - it's certainly not something I would usually do but I felt that it was best to publish this series all together as a set. I'll avoid doing this again in future. Thanks :)
