       flsudoku - the fltk sudoku game


       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.
