## What is Sudoku?

Sudoku, mastered.

Sudoku-ru is the sudoku app you'll actually keep on your home screen. A premium board, a daily challenge that grows your streak, four game modes, and a hint engine that teaches sudoku — not one that just hands you the answer.
FOUR WAYS TO PLAY Classic 9×9 — the original Mini 6×6 — perfect for a quick run Sudoku X — both diagonals must also contain 1–9 Killer Sudoku — cages with sums replace given clues

FIVE DIFFICULTY TIERS Easy, Medium, Hard, Expert, Evil — every puzzle is uniqueness-verified, so there is always exactly one solution.
DAILY CHALLENGE A fresh puzzle every day, seeded so it's the same for everyone. Build your streak, hit your best time, and watch the calendar fill up.
A HINT ENGINE THAT TEACHES The hint chain detects Naked Singles, Hidden Singles, Naked Pairs, Pointing Pairs, and X-Wing — and names the technique so you actually learn it, not just the next digit.

DESIGNED TO RESPECT YOUR TIME Pencil notes with auto-clear, unlimited undo and redo, peer and error highlighting, mistake limit with a one-time Watch-Ad revive, and iCloud sync so your streak and stats follow you to every device.
STATS AND ACHIEVEMENTS Win-rate chart, streak rings, per-difficulty time breakdowns, and a trophy case you unlock as you play.
SUDOKU-RU PREMIUM — one-time purchase Remove all ads, unlock every theme, and keep your hint tokens forever. Hint Packs (3, 20, or 100 tokens) are also available as one-time consumables.

Sudoku-ru works fully offline, syncs across devices via iCloud, and has no subscriptions.

## Version history (last 3 releases)

### 1.1.1 — 2026-08-12

This update makes Sudokuru easier for everyone to play:

• VoiceOver support — the board and number pad now read aloud, so you can play entirely by ear. Each cell announces its row, column, value, and state (given, filled, note, error, or selected).
• Color-blind assist — mistakes are now marked with a symbol, not just red, so errors are clear no matter how you see color. Toggle it on in Settings.

Thanks for playing!

Shorter one-liner (if you're tight on space):

Now with full VoiceOver support and a color-blind assist mode — Sudokuru is more accessible than ever.
