## Description

Five difficulties from Easy to Extreme, a daily puzzle everyone shares, and
notes you write in pencil. No hints, no game-overs — just you and the grid.

A classic sudoku with the soul of a paper puzzle.

The givens are printed in crisp type; your answers go in with a handwritten
pencil touch. It feels less like a screen and more like the puzzle page of a
morning paper.
