Zenoku is Sudoku the way it should be: beautiful, fast, and completely free of ads. No banners, no videos, no interruptions — ever.
CLASSIC SUDOKU, BEAUTIFULLY INKED
A crisp, newspaper-inspired design that stays out of your way. Every puzzle is generated with exactly one solution — you never have to guess.
FIVE LEVELS, EASY TO EXTREME
From relaxed morning solves to puzzles that demand real technique. Each level has its own rules for mistakes and hints.
A NEW CHALLENGE EVERY DAY
One daily puzzle, the same for every player in the world. Difficulty climbs through the week — build your streak and keep it alive.
SMART TOOLS THAT KEEP UP WITH YOU
• Pencil notes that clean themselves — place a number and it disappears from the notes of every related square
• Tap any number to light up every copy on the board
• Row, column, and box highlighting as you play
• Undo, erase, and hints (they cost points — spend them wisely)
COMPETE AND PROGRESS
• Game Center leaderboards for every level — best score and best time
• A milestones gallery full of goals to chase, with live progress
• Lifetime statistics: win rates, best times, perfect games, streaks
• Satisfying celebrations when you complete a row, column, or box
MADE TO RESPECT YOU
• No ads, no subscriptions, no paywalls — the whole game is free
• No account, no sign-up — your progress lives on your device
• No data collected. Period.
• Works completely offline
Pick up Zenoku for two minutes or two hours. The puzzle is waiting — and nothing else is.
Hints, reimagined. Hints now walk you through the answer in three quick steps right on the board — the numbers doing the work, the block being scanned, and why only one square is left. The board stays fully visible the whole time.
Sharper notes. Select any number and it stands out in bold everywhere you've noted it.
