Printable sudoku
Fill the grid so that every row, every column and every 3 × 3 box holds the digits 1 to 9 once each. Each of these grids has a single solution and can be reasoned all the way to it — no guessing, however tricky the level.
Every day there is a new grid at each of three levels, dealt to everybody alike. Pick a level, print the sheet, and take it wherever a screen would not go.
