Classic Sudoku for people who like to think, not to be rushed. Play at your own pace: no forced timers, no pressure, and the game never interrupts you in the middle of a puzzle.
SIX LEVELS GRADED BY TECHNIQUES
From Very Easy to Extreme. Difficulty is measured by the solving techniques a puzzle actually needs (singles, pairs, X-Wing and more), so "Medium" really feels like Medium. Every puzzle has exactly one solution.
HINTS THAT EXPLAIN WHY
Stuck? Ask for a hint and see which technique applies, which cells matter and why a digit goes where it goes. You learn something new with every hint. The classic "Reveal a digit" hint is still free and unlimited.
DAILY CHALLENGE
A new puzzle every day, the same for everyone. Build a streak, browse the calendar and collect a small daily reward.
BUILT FOR COMFORT
• Large print, adjustable fonts and a high-contrast theme: easy to read for seniors and anyone who prefers big digits
• Paper, sepia, slate and dark themes (follows the system dark mode)
• Notes and auto-notes, undo and redo, error highlighting you can switch off
• Two input styles: cell first or number first
• Optional mistake limit mode for a bigger challenge; the default is relaxed play
TOOLS FOR PUZZLE FANS
• Solver: enter any puzzle from a newspaper or a book and let the app solve it step by step
• Custom puzzles: save your own grids in "My games" and play them later
• Detailed statistics for every level: wins, best and average times
OFFLINE
Works without internet. Your game is saved automatically, so you can leave and come back any time.
ABOUT ADS
The app is free and contains ads. A full-screen ad can appear only after you finish a puzzle, never at launch and never in the middle of a game. Optional rewarded videos give extra hints. There are no purchases.
ALREADY PLAYING?
Your statistics, saved game, custom puzzles and settings are kept after the update. The familiar game screen stays where you remember it, and your old themes and fonts are still available.
