Sudoku Mentoring

Stop guessing. Start solving. Sudoku Mentoring teaches you how to actually solve sudoku — not just complete it by luck. Whether you're stuck on medium puzzles or ready to tackle expert-level techniques, every feature here is built to make you better. LEARN A GROWING LIBRARY OF PROVEN TECHNIQUES Go beyond scanning and guessing. Master the same logical techniques real solvers use — Naked Singles, Hidden Singles, Naked & Hidden Pairs and Triples, Pointing Pairs, Box/Line Reduction, X-Wing, XY-Wing, Swordfish, and more added as you progress. Each technique is taught in order of difficulty, so you always know what to learn next. PRACTICE WITH A GUIDED TRAINER The Trainer walks you through one technique at a time on hand-picked puzzles built to require it — no luck involved. You'll see exactly where and why each technique applies, with a clear explanation every time. Complete lessons to unlock the next tier and build real skill, not just a streak of completed grids. HINTS THAT TEACH, NOT JUST SOLVE Stuck on a live puzzle? Tap a hint and get a progressive explanation — first a nudge toward the right area of the board, then the technique name, then the full logic — so you learn the reasoning instead of just filling in a number. Flip on the Difficulty Overlay to see every technique currently available on your board, color-coded by tier. DIFFICULTY THAT MEANS SOMETHING Easy, Medium, Hard, and Expert puzzles are graded by the actual techniques required to solve them — not just clue count. A puzzle is only "Hard" if it truly needs Hard-tier logic to crack, so the difficulty label always matches the challenge. DAILY CHALLENGES & STREAKS A new puzzle every day, with your solve streak tracked automatically. Come back daily to keep it going, and take on Hard and Expert daily challenges once you've unlocked them. PLAY YOUR WAY Choose how mistakes are handled — from a relaxed Zen mode with no feedback, to Conflict Check and Solution Check, up to a high-stakes 3 Strikes mode — and pick from Light, Dark, or Sepia themes to match your style. WORKS FULLY OFFLINE, NO ACCOUNT NEEDED No login, no ads, no internet connection required to play. Your stats, streaks, and progress stay on your device.
