Rules: Normal sudoku rules apply. Circles and dots: Place nine circles in the grid: one in each row, column, and 3×3 box, with the circled cells forming a complete set of the digits 1–9. Digits separated by a dot differ by the circled digit in their shared row or column. For example, if the circled digit in a column is 3, digits separated by any dot in that column differ by 3. Not all possible dots are necessarily given.
Lösungscode: Row 1

What an original idea.

Shockingly approachable, though not at all easy! Was amazed to see the kinds of deductions you could make even before determining a single digit

Took me quite a while to really get the implications of the logic and know where to look.

Amazing puzzle. Really cool to get the hand of the rule and see the puzzle unravel. Very rewarding in the end.

I love puzzles like this. They make you think about their rules and discover new things, without being too hard either. A real treat, keep them coming. Thank you!

That was absolutely gorgeous! Really fun logic, lots of stuff to spot, I didn't get stuck anywhere, but it was not "obvious" where to look, and there was a bit of cool bonus logic to do mid-solve. Thank you Kaktuslav!

Refreshing ruleset new to me. Great logic. 2.5* from my solve time. Fun every second. Brilliant setting thx.
