## What is 数独集?

Make Sudoku part of your day. Start with a guided lesson or a classic puzzle, then explore new ways to reason with different rules.

Classic Sudoku and five variants
Explore Classic, Killer, Thermometer, Diagonal, Jigsaw, and Arrow Sudoku. Browse by difficulty and chapter, with rules for each puzzle type.

Practice at your own pace
Use notes, undo and redo, hints, and automatic candidates. The 300 beginner Classic levels and 24 lessons are free, with previews for other difficulties and variants and separate samples from curated packs. 

Keep your practice on your device
Save progress, results, and practice records locally, and continue unfinished solo puzzles. More regular puzzles, focused training, detailed reviews, and some themes require an active Pro entitlement.

Play with someone nearby
Connect two compatible devices on a local network and get ready together. Local network permission is required. Each player needs their own access to any Pro puzzle used in a match.

Solo practice does not require an app account or an ongoing internet connection. Purchase verification and restoration require internet access. Restoring purchases does not synchronize game progress between devices.

Includes English, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, French, Spanish, Brazilian Portuguese, and Italian. The interface follows your system or per-app language preference.

Pro Lifetime is a one-time purchase with no automatic renewal. The price is shown by your local App Store. Valid purchases can be restored in the app. Purchasing does not award experience, stars, or a competitive advantage.
