THE minimal sudoku
(Published on 6. July 2021, 13:52 by sandini)
If you write all nine rows as a single line, you get a huge number with 81 digits. This number must be as small as possible.
Solution code: Row 9

Now for the sequel - what's the second in line?

I was screaming at my monitor solving this like "that´s brilliant haha".

Tolle Idee und ein überraschendes Ergebnis! sandini, meiner Meinung nach könntest du hier die selten genutzten Labels "Optimierrätsel" und "Metarätsel" ergänzen.

Amazing. For me it was actually quite easy because recently I've been thinking about an algorithm that generates every single possible sudoku. I came up with an algorithm, and if I would run this algorithm the solution to your puzzle would actually be the first sudoku that was generated.

I don't know why but this wasn't super easy for me. Definitely needed the link ;) very fun puzzle!

Really nice, a novelty. Liked it a lot, even if it was very easy. (Probably my fastest solve ever).

@uvo: Ja, es ist im engeren Sinne eine Optimierungsaufgabe. Ich denke, meine Minimalitätsregel könnte auch gut kombinierbar sein mit anderen Sudoku-Vorgaben wie z.B. VX oder Thermometern, um weitere interessante (und schwierigere) Rätsel zu erstellen. Dies hier ist die Basisvariante als Anregung zum Ausbauen :-)

very fun concept - made me smile

@SKORP17: Ich kann dir auf jeden Fall versichern, dass eine kleinere Lösung möglich ist, du hast noch nicht das Optimum gefunden.
@sandini: Wenn es wieder möglich ist, Stichwörter zu setzen: Hier würde "Optimierrätsel" sehr gut passen.

Such a simple concept yet still fun to solve! I wish I had come up with this puzzle :)
P.S.: it's easy to miss the correct solution, I had to recheck two times...

This is a hard rule, if it isn't an empty grid, which would be really aggravating. One dot can cause way too much trouble

Very fun constraint, solved it in 6 min so it was a short but pleasant moment !
