## What is Sudoku Ember?

Sudoku should feel like a satisfying conversation with logic—not a fight with the interface.

Sudoku Ember is a calm, private place to solve, learn, and steadily become better. Every puzzle is generated on your device and checked for a unique solution under its real rules.

LEARN THE MOVE, NOT JUST THE ANSWER
• A proof-based Coach explains the logic before revealing a digit
• Ten interactive Academy lessons build techniques step by step
• Difficulty cards tell you what kind of reasoning to expect

SOLVE YOUR WAY
• Fresh Beginner, Easy, Medium, Hard, and Expert puzzles
• Classic, Diagonal, Killer, Thermo, and Arrow rules
• Cell-first or persistent digit-first input
• Smart candidates, notes, erase, undo, and matching highlights
• Daily Ember calendar, spoiler-free sharing, and optional Game Center leaderboard

BRING ANY PUZZLE
Paste an 81-cell grid or scan a printed puzzle. Recognition and validation happen on device, with an editable review before play. Apple Pencil input and an adaptive layout make Sudoku Ember at home on iPad too.

PRIVATE AND CALM
No account, ads, or third-party analytics SDK. Optional iCloud sync uses your own Apple account, and the full game works offline.

Beginner, Easy, Medium, Daily Ember, and Academy are free and ad-free. Sudoku Ember Pro unlocks Hard, Expert, every variant, statistics, unlimited Coach hints and undos, and all themes. Choose yearly with a 7-day trial for eligible new subscribers, or a one-time lifetime purchase. Optional Support Development tips do not unlock Pro features.
