Just Sudoku

Just Sudoku overview

Just sudoku. No ads, no fake currency, no nonsense. A clean number puzzle that respects your time. Pick a difficulty, solve, repeat. Every puzzle has one solution and is solvable by logic alone, so you never have to guess. Five difficulties, from Beginner to Expert. Beginner sticks to naked singles. Easy adds hidden singles. Medium brings locked candidates. Hard leans on pairs and triples. Expert opens up X-wings and beyond. A fresh Daily puzzle every day, the same one for everyone, so you can compare how you did. Pencil marks, candidate highlighting, a hint when you want one, mistake checking when you ask for it. The tools are there, and they stay out of the way until you reach for them. Everything runs on your device. Nothing is collected, nothing is uploaded.
