Why do I make puzzles? A brief history of Djape.net

Comments on Daily Killer Sudoku and Weekly Samurai Sudoku

Long time ago, some 5 years or so, I closed down the comments on the daily killer sudoku page and the samurai sudoku page. Why I did that? Because there were too many comments and the pages were loading very slowly. This was probably the worst and most stupid thing I’ve done with this website, […]

The June newsletter – INSANE Killer Sudoku puzzle

This is the insane puzzle I tried sending in June. It seems like it didn’t work. Here it is instead. It’s been a while, hasn’t it? 🙂 I can’t remember when was the last time I posted an INSANE Killer Sudoku puzzle. The INSANE rating is reserved for puzzles that might require some guessing OR […]

Newsletter problem? Or not?

Yesterday I sent out a newsletter with an INSANE killer sudoku puzzle. However, many e-mails bounced back, so I’m wondering if any of you received it or not? I moved the website to another server recently, so this could be causing problems. Please let me know. 🙂 Thanks!

Here’s another Anti-Chess sample puzzle: this one’s a bit harder than the last one. This one’s a HARD (4/5…BRAIN/IQ) Anti-King Killer (this puzzle was originally classified insane, but is actually easier than the insane puzzles in the book) Anti-King means that no two cells one king’s move move away from each other in chess can […]

Overlapping CalcuDoku (Square Wisdom, MathDoku) puzzle

It’s been quite a while since I last posted a CalcuDoku puzzle. I’m going to fix that now and to make it up to you, it will be a somewhat special variant of Square Wisdom puzzles. It’s an overlapping, 2 in 1 (Gattai-2), CalcuDoku puzzle, which is essentially in a TwoDoku layout. Remember the rules: […]
