Major Dominoes (6x6 Helping Cages)
(Published on 4. October 2026, 13:28 by sujoyku)
I am thanking all who tested it and wish you joyful solving!
Rules:
- Normal 6x6 sudoku rules apply, i.e. each Row, Column, and 2x3 Region has to contain the digits from 1 to 6 once each.
- Helping Cages: Digits in a cage must not repeat and no two cages may have the same sum.
No cage sums to its own clue, but receives help from exactly one other cage. That is, the clue indicates the sum of the cage it is in plus the sum of a helper cage, which is another cage to be determined by the solver.
Each cage helps exactly one other cage.
Cells outside the grid can be used for note-taking.
Here you can solve the puzzle online:
Solution code: Row 4 from left to right (6 digits in total)

Thank you for your comment, jubengo! I am glad that you liked the puzzle. Difficulty was really hard to estimate for this one. It is a case of "will feel very easy to some and at the same time challenging to others". Thanks for sharing your take on difficulty.
Kind regards, sujoyku

Nachdem ich kürzlich ein CtC-Video gesehen habe, das eine 9x9-Version von dir mit derselben ausgefallenen Regel vorstellte, war diese kleine Schwester natürlich ein Muss - und ebenso ein Genuss! Vielen Dank dafür.

Sehr gern geschehen, Franjo, vielen Dank für deinen Kommentar! Es hat mich total gefreut, dass Simon das 9x9er bei CTC gelöst hat. In kleineren Gittern ist die Variante etwas einfacher, da man weniger Käfige benötigt und es leichter ist, die Übersicht zu behalten. Es freut mich, dass es Dir Spaß gemacht hat.
Herzliche Grüße, sujoyku
