Passend dazu: heute vor einem Jahr habe ich mein erstes 4-Sterne-Sudoku nach dem Bewertungsmaßstab bei Logic Masters gelöst.
Das hat mich so sehr gefreut, dass ich mir das extra aufgeschrieben habe. Der Schwierigkeitsmaßstab bei Logic Masters wird von den Leuten nicht-linear angewendet, sodass mir vier oder gar fünf Sterne im Normalfall viel zu schwierig sind. Drei Sterne dagegen sind aber überwiegend gut machbar.
Auf den Tag genau vor zwei Jahren habe ich die Domain sudoku-tools.com registriert und meinen kleinen Killer Cage-/Region Sum Lines-Calculator installiert.
War tatsächlich nur für mich gedacht, wird aber von immer mehr Leuten genutzt (werbe- und trackingfrei).
Did some playing around with #GenAI's.
All of them could explain the German Whispers rule of variant #sudoku, but most of them would list 5 as a high digit.
All of them would accept 6-1-7-2-8-3-9-4 as a valid German Whispers line and 6-1-7-2-8-3-9-4-5 as a valid row in a sudoku.
None of them would accept that you could make a 8 cell long German Whisper line in a single row of a sudoku. All claimed that the theoretically longest line would be 6 cells long, but in practice only 4 cells.
Here are some new sudoku variants I made:
Zo, de kwalificatie voor het NK er toch maar even (tussen)doorgejast vandaag, voor de oefening. Ik zou er vanalles over willen zeggen, maar dat doe ik nog even niet, want de kwalificatie staat nog open tot maandag 12 uur.
Wow, mighty impressed by Google Gemini 2.5 pro. With help of ChatGPT o1 I had created python code to solve Sudokus and to Generate Sudokus. For the UI I wanted to try out Gemini.
So I wrote a single prompt, more a spec, of the UI features I wanted.
And the AI delivered a perfectly working, beautiful UI, even with some features I hadn't specified so clearly.
Here's the prompt:
You are an expert python developer.
Below you find python code that can solve and generate sudoku puzzles.
Please write python code for a tk user interface that allows users to solve sudoku puzzles generated by this code. The UI shall have these features
* button to generate a new puzzle, with a difficulty between 1 and 10. Based on the difficulty, use generate_random_start_board, followed by generate_sudoku(startboard, difficulty).
* see the sudoku in standard sudoku layout with clearly separated 3x3 spaces. Use large cells. A cell holds up to 9 very small numbers of what the user thinks are possible numbers, and one large number with the value for the cell the user chose.
* possibility to click into a cell which marks the cell as active
* a toggle (you decide which kind) that decides what happens if the user types a number. If the toggle is "domain" (please find a better word) then you add/remove one of the small numbers. If the toggle is "value" (please find a better word), then you enter the actual value of the cell.
* a button to check whether the solution is still valid, with appropriate means of showing this to the user.
* a restart button
* a "new puzzle" button
And here's two screenshots. Isn't this mindblowing?
Maar nu eerst: het instructieboek bestuderen voor de online kwalificatie van de Nederlandse Kampioenschappen Puzzelen en Sudoku. Deelname staat open voor iedereen die geïnteresseerd is.
Het zijn sowieso gewoon hele leuke puzzels die je lekker thuis kan printen en oplossen.
Wil je er meer over weten, tips & tricks, een keer gezellig samen puzzelen, een privé online trainingskamp of weetikveel: trek me aan mijn mouw!
I wrote a step by step tutorial on coding a Sudoku solver in just 100 lines of Rust. What do you think?

After trying out #deltachat and #arcanechat, I've discovered the #webxdc app store. My Dad loves #Sudoku puzzles, and I was tempted to play some competitive Sudoku with him. What assurance is there that there are no sketchy apps in the webxdc app store? Can these apps break out of their little jail, and root my phone? What would the #infosec community say? There's somewhat of a thread on the "threat model"/security of webxdc here (but I think it still needs more scrutiny):
