Big, easy-to-read sudoku with 1000 levels. No mistake limits, no rush.
Grand Sudoku is sudoku built for reading comfort first. Big numbers, a clean board, no mistake counter ticking down while you think, and no timer pressuring you to hurry. Whether you are new to sudoku or have solved thousands, all 1000 levels are open to play from the start, at whatever pace suits you. WHAT MAKES GRAND SUDOKU DIFFERENT Designed to be read from across the room, not squinted at. Every number and grid line is sized for comfortable reading, so you are not fighting the app just to see which cell is which. No mistake limit, no time limit, ever. Take as long as you need on any puzzle. There is no penalty for a wrong guess and nothing counting down while you think, so a puzzle never turns into a race. Puzzles that build skill gradually. The 1000 levels are generated with techniques that escalate step by step, from simple single candidates up through locked candidates, pairs, triples, and X-wing patterns, without jumping into advanced chain logic that would frustrate a casual player. EVERYTHING FOR A RELAXED SUDOKU HABIT - 1000 levels, all open to play from the start, no unlocking required - Daily puzzle: a new challenge every day, the same puzzle for every player around the world - Infinite mode: generate a new puzzle on demand whenever you finish your daily levels - Big, high-contrast numbers and a clean board, easy on the eyes at any age - Progress syncs automatically across your devices via iCloud, so you can pick up a puzzle on a different device without losing your place - Light and dark themes HOW PEOPLE USE IT Open the app whenever you have a few spare minutes, whether that is a morning coffee, a waiting room, or a quiet evening, and pick up exactly where you left off. Work through the 1000 levels at your own pace with no deadline, or play the daily puzzle to compare notes with friends and family who are solving the same board that day. When you finish everything queued up, infinite mode keeps generating fresh puzzles so you are never stuck waiting for new content. FREQUENTLY ASKED QUESTIONS Do I have to unlock levels in order? All 1000 levels are open to play from the start, at your own pace, in any order you like. Is there a time limit or a mistake counter I need to worry about? No. There is no timer counting against you and no limit on wrong guesses. Take exactly as much time as you want on every puzzle. Will the puzzles suddenly get too hard? The 1000 levels are built around a gradual difficulty ladder, so the techniques you need build up step by step rather than jumping straight into advanced logic. Does my progress carry over if I switch devices? Yes. Progress syncs through iCloud automatically, so your streak and completed levels follow you to a new iPhone or iPad. What does Grand Sudoku Pro add? Pro gives unlimited hints instead of 3 hints a day, and unlocks Master Mode with expert-level boards for players who want a tougher challenge beyond the main 1000 levels. GRAND SUDOKU PRO (ONE-TIME PURCHASE) All 1000 levels, the daily puzzle, and infinite mode are included at no charge from the start, along with 3 hints a day and zero ads.
