747 Take-off
(Eingestellt am 19. August 2026, 20:37 Uhr von sujoyku)
Regeln:
- Chaos Construction: Teile das Gitter in sieben orthogonal zusammenhängende siebenzellige Regionen ein und platziere die Ziffern 1-7 je einmal in jeder Reihe, Spalte und Region.
- Kreise: Die vier Zellen um einen Kreis müssen entweder alle zu einer Region oder alle zu unterschiedlichen Regionen gehören.
- Target Sums: Ein Hinweis X außerhalb des Gitters gibt die Summe aller Ziffern in der Reihe oder Spalte an (angefangen von der Seite des Hinweises), welche vor der Target-Ziffer X vorkommen.
Beispiel: Eine Reihe mit einem Target Sums-Hinweis von 5 könnte 2351647 lauten, da die Ziffern 2 und 3, welche vor 5 kommen, sich zu 5 addieren.
- Angezeigte Regionen-Grenzen: Für jeden Hinweis außerhalb des Gitters gilt, dass alle Ziffern, die Teil der Summe sind, zur gleichen Region gehören, während die Target-Ziffer X zu einer anderen Region gehören muss.
Hier kann das Rätsel online gelöst werden:
Lösungscode: Reihe 5 von links nach rechts, wobei das Symbol "/" Grenzen zwischen Regionen markiert (z.B. 12/345/67)

Very nice and accessible puzzle! I gave it 2 stars, though, I found it (just) too tricky for a 1 star puzzle. (Even though I had just finished Accuracy, which certainly helped for this one.)
**
Thank you for your comment, mscha! I am glad that you liked the puzzle. I agree with your assessment, I also think it is rather 2* (as which I initially posted), but the borders between tougher 1* and easy 2* might be fluent anyways. Thanks again for giving your feedback!
Kind regards, sujoyku

36:30 minutes to solve. Not the easiest Chaos Construction puzzle I've solved, felt too tricky to be GAS. The CC puzzle with target sums from Prof.Dori was definitely easier
**
Thank you for your comment, JVA! I did not mean to imply this was very easy, just thought it was more approachable than my first two CCs (which turned out to be 3*s). To be honest, I am surprised this got rated 1*, initially I uploaded it at 2.
Kind regards, sujoyku

Enjoyed this new target constraint especially in a 7 by 7. Great puzzle just before bedtime.
**
Thank you for your comment, GeorgeTheToad2! I am glad that you enjoyed it as a little puzzle snack before bedtime. I am also curious how this constraint will do in 9x9. With its limited "range", it works really well in smaller grids.
Kind regards, sujoyku

I've been really loving this target sums constraint, from the few puzzles I've played with it. This one is no different. A very fun solve.

Nice twist of the X-sum ruleset! Thanks :)
**
You are much welcome, Christounet, thank you for your comment! I quickly began to like the constraint when Dorlir explained it to me first. :)
