How to play

Fill the grid so every row, column, and 3×3 box contains the digits 1–9 exactly once. Select a cell, then tap a number or type it. Switch on Notes to pencil in candidates before you're sure. The Daily puzzle is the same for everyone and resets at midnight — solve it to keep your streak alive.
