NAME

       flsudoku - the fltk sudoku game

SYNOPSIS

       Sudoku is a FLTK-based version of the game of Sudoku.  Sudoku (pronounced soo-dough-coo with the emphasis
       on the first syllable) is a simple number-based puzzle/game played on a 9x9 grid that is divided into 3x3
       subgrids. The goal is to enter a number from 1 to 9 in each cell so that each number appears only once in
       each column and row.

       At the start of a new game, Sudoku fills in a random selection of cells for you -  the  number  of  cells
       depends  on  the  difficulty  level  you  use.  Click  in any of the empty cells or use the arrow keys to
       highlight individual cells and press a number from 1 to 9 to fill in the cell. To clear a cell, press  0,
       Delete,  or  Backspace. As you complete each subgrid, correct subgrids are highlighted in green. When you
       have successfully completed all subgrids, the entire puzzle is highlighted until you start a new game.

       As you work to complete the puzzle, you can display possible solutions inside each cell  by  holding  the
       Shift  key  and pressing each number in turn. Repeat the process to remove individual numbers, or press a
       number without the Shift key to replace them with the actual number to use.
