Tentative Looping
(Eingestellt am 14. Juli 2025, 16:58 Uhr von sujoyku)
- Es gelten die normalen Sudoku-Regeln, d.h. jede Reihe, Spalte und 3x3-Region muss jede der Ziffern von 1 bis 9 genau einmal enthalten.
- Tenline-Loop: Zeichne einen eine Zelle breiten Loop (geschlossenen Pfad) in das Gitter. Der Loop darf sich nur orthogonal von Zelle zu Zelle bewegen, sich nicht verzweigen oder kreuzen und sich weder orthogonal noch diagonal selbst berühren.
Zusätzlich dient der Loop als eine Tenline, d.h. er kann in zusammenhängende, sich nicht überschneidende Segmente eingeteilt werden, deren Summe immer genau 10 ergibt.
- Loop Sum-Hinweise: Hinweise außerhalb des Gitters geben die Summe aller Ziffern AUF DEM LOOP in der entsprechenden Reihe oder Spalte an. (Ziffern, die sich nicht auf dem Loop befinden, tragen in beiden Fällen nicht zu der Summe bei.)
- Connecting Kropki: Durch einen weißen Punkt verbundene Zellen müssen aufeinanderfolgende Ziffern enthalten. Zudem liegt genau eine der beiden Zellen auf dem Loop und die andere nicht.
Durch einen schwarzen Punkt verbundene Zellen enthalten Ziffern mit einem 1:2-Verhältnis. Zudem sind entweder beide Zellen Teil des Loops oder keine der beiden Zellen ist Teil des Loops. (Nicht alle Punkte sind angegeben.)
Hier kann das Rätsel online gelöst werden:
Lösungscode: Ziffern auf dem Loop in Reihe 4 von links nach rechts

Very nice puzzle - I enjoyed it a lot :)
It was so fun figuring out where the loop went. Thanks for the puzzle :)

Lovely puzzle! I'll have to take everyone's word that the break in was great, I remember it took me forever to get a digit, but this was a 3 day (150 minutes) solve for me so I don't even remember at this point. The whole puzzle was very nice, I really enjoyed it :)

Thank you for your comment, davidz32z! I can definitely relate: Sometimes I ask myself at the end of a challenging solve "How did I solve this?". :)
Thank you for sticking with the puzzle! I am glad that you enjoyed it.

I think this may have been my first time solving a 3* without hints or bifurcation. And it took me about an hour which normally would be long enough that I get frustrated and give up without making progress.
So what I'm saying is that this was a fantastic puzzle that was clever and challenging without ever feeling frustrating or unfair. Amazing!

Congratulations, cowabunghole, and thank you for your comment! I am glad that you enjoyed the puzzle.

Very clever and tricky break-in, then a strong flow with the line after that. I really liked the kropki/loop restriction.

Thank you for your comment, MattYDdraig! I am glad you enjoyed the puzzle and liked the Connecting Kropki constraint.

I found this a bit harder than 3*, but I chipped away at it throughout today and now solved it! Great construction as always. Thank you for the nice puzzle :)
**
Thank you for your comment, SamuPiano! I am glad that you liked the puzzle. Considering difficulty: I believed the break-in phase to be a little harder and the later stages to be easier than 3 stars. But as a setter, I always find it difficult to estimate. Thanks for sharing your perspective.

I didn’t need the tens rule until the very end - at which stage I had forgotten the rule and was confronted with a deadly pattern.
**
Thank you for your comment, cozmic72!
Good that the tenline rule is included then. :)

Lovely--an approachable but non-trivial break in with a very smooth flow.

Lovely puzzle, thanks! I used the tenline rule a lot (unlike some others it seems) but instead only used about half of the outside clues.

Thank you for your comment, Exigus! I am glad that you liked the puzzle.

very nice. First applied the same rule to white & black dots but that got me nowhere.:-)
Thanks

Very nice puzzle. Completely forgot the Tenline rule. Only needed it at the very end to disambiguate a deadly pattern.

A lovely balance of logic between the constraints used. Very enjoyable, thanks for sharing!

Thank you for your comment, rameshsrivats! I think the tenline makes the puzzle more approachable. In any case, I am glad you liked it.

Gorgeous puzzle! I really liked how far I could get in the solve without using (which actually means noticing) the ten line constraint. Thank you
**
Thank you for your comment, Snookerfan! I am glad that you liked the puzzle. Also I think I know exactly what you mean. You can do a lot before considering the implications of the Tenline constraint.
Kind regards, sujoyku
