Building a puzzle with exactly one solution…
How to play
- Every row, column and 3×3 box must contain each digit from 1 to 9 exactly once.
- Tap a cell then a number, or use the arrow keys and number keys.
- Notes and undo are normal play and do not affect your records.
- A hint fills in one cell and marks the run assisted; assisted times are kept separately.
- Every puzzle is checked to have exactly one solution. Easy and Medium are graded by the techniques needed, not the number of clues.
- The timer starts on your first entry and pauses when you leave the tab. Records are kept on this device only.
