Crosshatch

One move. Then the next.

Crosshatch gives you room to work through Sudoku at your own pace. Choose a collection, follow the rules it names, and return to your saved puzzle whenever you are ready.

FIVE COLLECTIONS
Explore 10,341 included puzzles across box cross-hatching, row and column scans, locked candidates, thermometers and Killer cages. Each collection explains the techniques or rules it uses.

QUESTIONS THAT ASK FOR YOUR REASONING
Ask me guides box and line questions by asking you to rule out cells. It does not reveal the solution. The guide covers box and line questions; locked-candidate eliminations and variant-specific rules are not fully taught. Fog play has its own rules and does not include guided questions.

MAKE IT YOURS
Start with Print or choose one of four other appearances. Adjust Larger text, grid lines, motion, sound level and haptics. Enter manual pencil notes, undo moves, and review your recorded practice in the journal.

YOUR PUZZLE, READY WHEN YOU ARE
The included puzzles and local saves work offline. No Crosshatch game account is required. Progress stays on your device; Crosshatch does not provide account-based cloud saves.

ADS BETWEEN PUZZLES
Advertising is limited to breaks after completed puzzles, with eligibility, privacy and frequency checks. Ads do not interrupt a puzzle or unlock its teaching. An optional one-time Remove Ads purchase removes all advertising. There is no subscription.

Purchasing, restoration, privacy messages and advertising can require an internet connection. Their availability depends on the optional age/privacy profile and applicable provider checks. You can keep playing without setting that profile.
