## What is Sudoku Arena Online?

Sudoku Arena Online is a calm, type-driven Sudoku for players who want their puzzles served thoughtfully — generous typography, real puzzles, and live multiplayer when you want company.

CHOOSE A PUZZLE
Four difficulties — Easy, Medium, Hard, Expert. Every board is generated locally with a uniqueness check, so the puzzle is fair and the answer is never ambiguous. Notes, hints, undo and a clear mistake budget are exactly where you would expect them.

A NEW PUZZLE EVERY DAY
The daily challenge ships the same board to every device on the same calendar day. Solve it to extend your streak; the home screen shows your current run and your best.

CONTINUE WHERE YOU LEFT OFF
Every solo board auto-saves. The Home screen shows your in-progress game on a dark "Continue" card with elapsed time and percentage, so picking up tomorrow takes a single tap.

BEAT YOUR BEST
Local stats track your fastest solve and total wins per difficulty. The numbers stay on your device — no leaderboard pressure, no comparison to strangers, just a private record of your own progress.

PLAY AGAINST A FRIEND, A STRANGER, OR THE AI
Real-time multiplayer in two flavours, plus a tireless AI opponent for the moments the queue is empty:

— Versus: race a random opponent on identical puzzles. The first to fill the board correctly wins; whoever runs out of mistakes first loses. Mistake counters are visible to both sides for that "I can still come back" tension.

— Co-op: two players share one board with a synced cursor and live progress. Designed for casual play with a partner — no pressure, just team logic.

— Play vs AI: a local bot opponent at the difficulty of your choice. Paces itself per tier so Easy is a friendly warm-up and Expert a real challenge — no internet required.

Pair with a friend via a 6-character invite code (Create Invite Code → share → friend Enters Code), or jump into the matchmaking queue for a random opponent. If no one is around within 15 seconds, the app gracefully offers an AI match at the same difficulty.

QUIET, PREMIUM DESIGN
A paper-toned Classic theme with hand-tuned typography — Newsreader for digits, Geist for UI labels, Geist Mono for timers and invite codes. Three additional themes (System / Light / Dark) from Settings. Three languages: English, Türkçe, Español.

YOUR DATA, YOURS
Sign in with Apple or Google, or skip sign-in entirely and play as a guest. We only collect what's needed to run sign-in and pair you with another player — and we never sell your data or share it with data brokers.

ACCOUNT DELETION
Settings → Delete account permanently removes your record from our backend and ends your session. Apple App Store Review Guideline 5.1.1(v) compliant.
