Sudoku
Fill the grid so every row, column and 3×3 box holds 1 to 9 once each. Tap a cell, then a number below the grid. With the keyboard, move with the arrow keys or W A S D and type 1 to 9; Backspace clears a cell. A wrong number turns red and adds 10 seconds. Turn on the pencil, or press N, to jot notes for free. To give up, press the Give up button twice. Finish in the shortest time. Press Escape to pause.
