Hey Product Hunt! 👋 I built Sudokun because I was tired of Swedish sudoku sites full of login walls, pop-up ads mid-puzzle, and machine-translated interfaces. Sudokun is different: → Zero accounts required – open the site and start playing → No ads inside the puzzle area, ever → 5 difficulty levels: Kids, Easy, Medium, Hard, Extreme → Full keyboard support (arrows, number keys, notes mode) → Printable PDF puzzles for classrooms and offline use → Every puzzle is algorithmically verified to have a unique solution It's built in Next.js, runs fast on mobile and desktop, and works entirely in the browser. Would love feedback – especially from non-Swedish speakers on whether the UX is clear enough despite the language!
