Handoku

Puzzle

Free · Designed for iPad. Not verified for macOS.

Handoku is a calm Sudoku app for taking your time with each number. • Tap a cell and enter numbers with the on-screen keypad. • Write digits directly into cells with Apple Pencil on a compatible iPad. • Keep candidate notes and undo your moves. • Explore hints step by step: location, reasoning, then the answer. Apply the answer only when you choose. • Try the daily puzzle or start a new puzzle at your preferred difficulty. • Zoom into the board and choose a left- or right-handed control layout. • Save your progress and return to your puzzle later. The clock is optional. Play at your own pace on iPhone and iPad. No account or internet connection is required.
