SudoMind: Sudoku Puzzle

SudoMind is Sudoku, done right: a clean classic 9x9 board, a fair hand-crafted difficulty curve, and zero guessing required from Easy all the way to Expert. Every single puzzle has exactly one solution you can reach through logic alone — no trial and error, no lucky guesses, ever (except one optional "Extreme" puzzle at the very top, and we tell you before you start). Play the classic game exactly as you know it, or work your way through a 10-chapter campaign that introduces four well-loved variants one at a time: - Diagonal Sudoku — the two main diagonals join the rules - Windoku — four extra shaded regions to satisfy - Killer Sudoku — cages that must add up, with no repeated digits inside - Jigsaw Sudoku — irregular regions instead of plain 3x3 boxes New rules are taught by the board itself — a highlighted example, not a wall of text — so you're solving within seconds, not reading a manual. WHAT'S INSIDE - 200 hand-tuned campaign levels across 10 chapters, Easy through Expert - A daily Sudoku with a streak calendar and gentle reminders - Adaptive Endless mode that quietly tunes itself to how you're doing - Notes (pencil marks) with one-tap auto-fill - Purist mode for players who want zero hand-holding, with its own "Purist Clear" badge — auto-check stays on by default for everyone else - Number-style and board-theme cosmetics you unlock by playing - Colourblind-safe conflict highlighting, adjustable text size, reduced- motion support - Fully playable offline — no account, no always-online requirement FAIR BY DESIGN No ad ever sits next to the board or the number pad. No ad is ever forced on a wrong answer. Every rewarded ad is something you choose to tap, never something in your way. Remove Ads is a one-time purchase if you'd rather see none at all. Whether you play one relaxed puzzle a day or chase every chapter's Perfect and Purist Clear stars, SudoMind is built to respect your time and your brain. Open it, and start solving.
