A sudoku, not a platform. Solid Sudoku is a classic 9×9 sudoku with a daily challenge — a calm, paper-styled logic puzzle, fully playable offline. Open the app, pick a difficulty, play. Try everything free for 7 days. One small unlock keeps the whole game. No ads, ever. Nothing else to buy. A REAL LOGIC PUZZLE Every puzzle is generated on your device and always has exactly one solution — solvable by deduction, never by guessing. Four difficulty levels run from a gentle Easy to a properly stubborn Expert. DAILY CHALLENGE One puzzle a day, identical for every player in the world. Solve today's grid and see how your time stacks up — an anonymous percentile against everyone else who played. No account. No usernames. Just the number. THE TOOLS YOU'D ACTUALLY USE • Notes mode for pencil marks — cleared automatically when you fill the cell • 3 hints per game. A hint adds 30 seconds to your adjusted time, so a solved grid still means something • Full undo and redo — the move history even walks back hints and mistakes honestly • Smart highlighting for the selected row, column, box, and matching numbers • The number pad counts down how many of each digit are left DESIGNED LIKE PAPER The whole aesthetic is called Clean Paper: a warm white page, clues that look printed, your entries in soft blue ink. A fresh puzzle page every game, with a touch of retro pixel charm at launch. NO INTERNET REQUIRED Fully playable offline. On a plane. In a basement. Puzzles are generated on your device — no WiFi, no cellular, no waiting for a server. Even today's Daily Challenge works offline; only the percentile needs a connection. Your game saves itself and resumes exactly where you left off. ONE HONEST UNLOCK The whole game is free for 7 days — every difficulty, every tool, nothing held back. If it earns a spot on your home screen, one unlock keeps it: a small yearly subscription or a one-time lifetime purchase. No ads, ever. Nothing else to buy. No account, no sign-in — purchases use anonymous store IDs, there's no ad tracking, and your data is never sold. A LITTLE STOIC CALM Stoic quotes from Marcus Aurelius, Epictetus, and Seneca rotate through the app. A small moment of philosophy before the logic starts. SUDOKU FEATURES • Classic 9×9 sudoku with four difficulties: Easy, Medium, Hard, Expert • Daily Challenge — the same seeded puzzle for everyone, every day • Unique-solution puzzles, generated instantly on device • Pause-aware timer — pausing never costs you time • Three mistakes and the round is over — gentle stakes, honest wins • Auto-save and resume across launches • Full hardware keyboard support on iPad — arrows, digits, shortcuts The whole game, right here.
