JazzIn is sudoku the way it should be: every puzzle can be solved with logic alone, step by step, without guessing. Beginner, Easy, Medium, Hard, Expert and Extreme. Each level is defined by the techniques it needs – from hidden singles to X-Wing, Swordfish, chains and, in Killer, innies and outies – so the difficulty grows smoothly and fairly. Stuck? A hint shows the next logical step and names the technique behind it, so you learn instead of just filling in a number.

Could you build this?
Yes Sudoku generation, solving, and hint UIs are well-documented, and a technique-based solver that grades puzzles by the logic they require is a known algorithmic task an AI assistant can help implement.
