## What is Clear Nines?

Clear Nines is a calm, focused Sudoku app built for repeated solving and real skill growth.

Play classic Sudoku puzzles across Easy, Medium, and Hard difficulty levels with a clean board, notes mode, undo, pause-aware timing, mistake tracking, and helpful row, column, box, and same-number highlighting.

When you want help, Clear Nines can do more than reveal an answer. Teach Me hints explain why a move works, and Expert Path shows a logical solving route so hints become lessons instead of shortcuts.

Features:
- Easy, Medium, and Hard Sudoku puzzles
- Notes mode for candidate tracking
- Smart board highlighting
- Quick hints and Teach Me explanations
- Expert Path solving walkthroughs
- Stats, streaks, best times, and mistakes
- Multiple readable themes
- Offline-first gameplay
- Optional account sign-in to sync purchases and entitlements
- Optional Premium upgrade to remove ads and unlock more learning tools

Your puzzle progress, stats, and settings stay on your device. Account sign-in is optional and is used only to sync purchases and entitlements across devices.

Improved account sign-in and reliability. Your puzzles, coins, and pending purchases stay saved when reconnecting your account. Includes fixes for syncing during temporary service interruptions.

### 1.0.1 — 2026-09-25

Introduces the new Raised board: a tactile porcelain-style Sudoku board with recessed 3×3 regions, lifted selection feedback, and a subtle placement animation. Optional haptics can be turned off in Settings, and the original Classic board remains available. This update also improves VoiceOver cell details, supports Reduce Motion and increased contrast, fixes matching-number highlights across 3×3 boxes, and keeps banner ads anchored below gameplay. Banner space now appears only after an ad loads and collapses automatically when an ad is unavailable.
