Herniated Ring
(Published on 3. October 2025, 19:36 by brtmns)
Normal sudoku rules apply.
A black dot separates two digits such that one is twice the other.
A white dot separates two digits that are consecutive.
Digits appearing in large circles (on grid intersections) must appear in the surrounding four cells.
Digits cannot repeat within a cage, and the digits within a cage must add up to the total given in that cage’s upper-left corner.

Solution code: Box 5.

Interesting. First try I struggled and struggled and finally ended up with an empty cell; oops. Second attempt went smooth and pretty fast and solved it in 16 minutes. 3 stars and/or 1 star.

Much harder than HR2! Glad I went back and found this one. Thank you.

Very nice! A bit of maths, a bit of rings and a smooth puzzle over all. Thank you

Very nice, but hard - took me 59 minutes and nearly gave myself a herniated ring in the process. Probably an even harder puzzle if solving without knowing about the other ring.

Glad you like it and sorry for your ring :)

If you are familiar with a certain ring it is quite easy to solve. I would give it 2*. No idea how it is without that certain knowledge though.
Thank you for that lovely puzzle!

I found this rather tricky. Thanks for sharing.
