|
.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. |
