Full description

Two ways to play, in one calm, offline puzzle app. CLASSIC SUDOKU Easy, Medium and Hard puzzles, each with exactly one solution. Number-first entry is the default: pick a number, then tap squares to place it. Prefer the other way round? Square-first is a setting. Pencil marks let you note candidates, Fill notes works out what is still allowed, and writing a number tidies the notes around it. Undo has your back. SUDOKU EXCHANGE A different way in. The board starts completely full, and every row is already correct. Swap two numbers within a row to repair the columns and boxes. Any valid Sudoku wins. Gold, silver and bronze medals reward an efficient repair. A DAILY PUZZLE, AND A STREAK WORTH KEEPING Everyone gets the same daily Exchange puzzle. Solve it to build a run of consecutive days. Every seventh solved day earns a rest day, held two at a time, so one busy day does not erase weeks of work. Your journal keeps current and longest runs, days played, medals and a 28-day ribbon. There is no currency and nothing to lose but the count. MADE TO BE CALM Three palettes: Signal, Blueprint and Print. An optional ambient soundtrack with its own volume, and gentle haptics. An optional daily reminder, off until you ask for it. Hide the timer if it puts you off your game. YOURS, ON YOUR DEVICE No account, no sign-in, no cloud saves. Puzzles are generated on your device, and your game, pencil marks, journal and best times all save locally. Plays completely offline.

What's new
