- .SH SYNOPSIS
- \fISudoku\fR 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.
- .LP
- 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.
- .LP
- 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.
