Nineward Sudoku

New this update: redesigned share cards for your daily results, calmer sound, and cleaner settings. Same deal as day one — no ads, no coins, no nonsense.

Sudoku should feel calm, sharp, and satisfying — not stuffed with ads, clutter, coins, popups, and twelve buttons nobody asked for.

Nineward Sudoku is a clean, modern Sudoku game built for people who want great puzzles, smart tools, and zero nonsense.

Play classic Sudoku, take on the daily challenge, try Killer Sudoku, race through Arcade Sprint, train on smaller boards, import your own puzzles, and sharpen your solving with hints that actually teach.

No forced ads. No fake coin economy. No "watch this video to continue having a personality." Just Sudoku, done right.

Play Your Way

• Classic 9×9 Sudoku • A daily challenge — everyone gets the same board • Killer Sudoku with cage sums • Arcade Sprint for fast 5-minute sessions • Mini boards for training and quick play • Custom puzzle import • Calm Mode for relaxed solving • Challenge Mode for clean, streak-worthy runs • Technique training to help you improve

Smart Tools, Not Screen Clutter

Nineward gives you the tools serious solvers expect without making the board look like a control panel from 2007.

• Pencil notes • Smart notes • Undo • Pause • Mistake tracking • Same-number highlighting • Row, column, and box highlighting • Remaining number counts • Auto-save • Clean touch controls • Dot notes and board-display toggles (Pro)

Hints That Actually Teach

A good hint should help you understand the next move, not just spoil the answer. Nineward's hints name the technique they use — naked single, pointing pair, X-Wing — so you get better over time.

Track Every Solve

See your progress, review your history, and replay completed games like game tape.

• Solve history • Stats • Streaks • Badges • Perfect solve goals • No-hint goals • Replay library (Pro)
