"Number Space" is a logic game

In "Number Space": a single cell is filled in with orange when the game is paused. Moving the mouse over this highlighted cell will resume navigation. Moving the mouse away from the Sudoku board will pause the game. To fill in the puzzle, navigate to a white cell and press a number key to insert a digit. At this point the row, column, and 3x3 block that contain the selected cell will be visible. In a solved puzzle each of these three areas will contain all of the digits 1-9. Press "backspace", "delete", or "0" to clear a cell. Press "escape" to return to the starting position. Click on the thumbnail images above to switch between puzzles. Reloading the page will erase your progress.
