Grid Zen · Daily Sudoku

Grid Zen is a sudoku game built around one idea: give you a clean puzzle and get out of the way. Whether you have five minutes between meetings or an hour to yourself, it opens instantly and puts you straight to work. No fanfare, no friction — just the grid and your thinking. What's inside - Classic 9x9 sudoku with Easy, Medium, and Hard difficulty levels - Easy mode opens with 38 to 42 given clues — enough to build momentum without hand-holding; Hard mode gives just 24 to 28, leaving plenty of room to earn every solution - A clean number pad designed for comfortable, accurate digit entry - Session stats that track your best time, best move count, and total games won across every difficulty - Fully offline — no internet connection needed, ever - No ads and no trackers of any kind - A minimal blue-tone design that fades into the background so the puzzle stays front and center - No loading screens, no tutorials to dismiss — the app is ready when you are Most puzzle games treat difficulty as a single slider and leave it there. Grid Zen takes it further by calibrating the exact number of starting clues at each level, so the jump from Easy to Medium to Hard feels earned rather than arbitrary. Easy is genuinely approachable for someone new to sudoku. Hard is a real test — not artificially obscured, just honestly sparse. You know where you stand from the moment the board appears. Grid Zen was designed to work entirely without a network connection, and that is not an afterthought. There are no ads to load, no analytics pinging a server in the background, and no account required. Your stats live on your device and belong to you. The app is small, launches immediately, and makes no demands on your attention beyond the puzzle itself. If you want a game that respects the time you give it, this is that game. One puzzle at a time. Your pace, your rules.
