Puzzelo Sudoku

A new Daily Challenge every day. Seven difficulty tiers, iCloud streaks, achievements, Siri shortcuts, and a beautiful iPad sidebar layout.

A clean, modern Sudoku that respects your time and your attention.

Seven difficulty tiers — from Beginner all the way to Extreme — generated to guarantee exactly one valid solution every time. Big readable cells, beautiful animations when you complete a row, column, or box, and a Smart Hint that points you at the easiest unsolved cell before you spend a hint to reveal it.

DAILY CHALLENGE A new puzzle every day, the same one for every player. Win it to extend your streak. A built-in calendar tracks the last six weeks. Eleven achievements reward your milestones, including 7-, 30-, and 100-day streaks.

SMART INPUT Two input styles you can swap at any time: • Cell-first — tap a cell, then a digit • Digit-first — tap a digit, then sweep across cells

Plus Auto Notes, double-tap to flip notes mode, long-press for quick candidates, and a Check button that flashes any wrong entries. Full hardware-keyboard support on iPad (1–9 to place, arrow keys to move, N for notes, H for hint, ⌘Z to undo).

LOOKS GOOD Six accent colors. Light and dark mode. iPad gets a proper sidebar layout that uses the larger canvas. Confetti when you win, with a diagonal accent wave that sweeps the board after a solve.

ACCESSIBLE Full VoiceOver labels on every cell ("Row 4, column 7, entered 5"), accessibility hints, scaled-up Dynamic Type, and explicit traits so the board acts the way iOS expects.

DEEP INTEGRATIONS • Hey Siri — "Play Sudoku", "Start daily challenge", "Start an expert game", "What's my Sudoku streak" • Spotlight shortcuts for the same commands • Home Screen widget showing your streak and today's status • Local notifications at your chosen time for the daily reminder • Share your win as a beautifully composed image • Export and import puzzles as 81-character strings — send your friends a custom board

iCLOUD Your statistics, streak, accent theme, and preferences sync between every device signed into your iCloud — automatically, encrypted, zero setup. The developer never sees any of it.

ADS + REMOVE ADS Puzzelo Sudoku is free to play, supported by occasional ads (banner under the board, an interstitial after a win, an optional rewarded video if you'd like an extra hint). One in-app purchase removes them permanently across all of your devices — your call.
