Herniated Ring-7

(Published on 3. November 2025, 20:53 by brtmns)

Normal sudoku rules apply.

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.

Digits appearing in large circles (on grid intersections) must appear in the surrounding four cells.

A black dot separates two digits such that one is twice the other.

A white dot separates two digits that are consecutive.

All the dots are given!

as is typical for this series, more hernia than ring.
negative constraint does the HEAVY LIFTING, right from the start

Also I am quite fond of this series. Struggled with this one and after having made some unknown error it ended up in mess. A restart was needed and thereafter it was smooth sailing into the harbor in about 30 minutes. Excellent.

Very nice but quite hard - 30 minutes for me.

This was a fun puzzle! Rulesets like this tend to produce more than one break-in and the one I found was rather obscure and probably not intended (also at least one cage was obsolete for me). Still I had fun, so keep them coming!

Wonderful break-in, great work.
