How to play

Pick a cell, then enter a digit with the number pad or your keyboard. Arrow keys move around the grid, Backspace clears a cell.

Switch on Notes (or press N) to jot down candidates in a cell. Digits you place are taken out of the notes of the cells that see them.

Check marks every digit that is wrong, Hint fills in one cell you can work out by logic, and Take back undoes your last entry. Daily puzzles are saved as you go, one per level.
