What Number am I thinking of? (NOT 5)

(Eingestellt am 21. März 2025, 16:29 Uhr von Br1312te)

Solve on Sudokupad. The puzzle can only be solved online due to the fog mechanic.

Rules:

Pick five digits from 1-9. Place those five digits in each row, column and box.

V's: digits connected by a V must sum OR subtract to 5. For example, 2+3 or 9-4 are both valid.

Parity: digits on a grey square are even. Digits on a grey circle are odd.

Kropki dots: digits connected by a white dot are consecutive.

Fog: the grid is partially covered in fog. Placing correct digits will clear the fog. No guessing is required.

I rated this 2/5 difficulty.

This was a really great puzzle! Absolutely beautiful puzzle, with such a nice logical sequence.

I agree with @Garizon that this was probably harder than 1* in terms of difficulty/complexity. My solve time was obviously very fast compared to the "average 2* sudoku", but this is obviously expected for a smaller puzzle (especially a 5*5), and the underlying logic was a bit too tricky for a 1* puzzle.

Each of the elements of the rules worked together nicely, and the way that the chosen digits were disambiguated/constrained was very nice and a really cool geometry.

I used some labeling and coloring tricks to be able to make progress at first. Figuring out how to effectively color/notate was definitely the hardest part for me, and this was probably the hardest 'aspect' of the puzzle - and is why I rated it 2* difficulty. By the time that I managed to place my first digit, the subsequent logic & fog reveal unraveled everything for me and I solved the puzzle quickly afterward.

Overall this was an excellent puzzle! It's a really good choice for a quicker solve, without any sacrifice to the beauty of the puzzle's logic.

P.S., I felt like the 'V' rules were a bit odd, but even so, they balanced out nicely with the rest of the other rules ;)

With the choose your own digit constraint I found this more difficult than 1*, especially given the size of the grid. Great puzzle thank you for sharing.
