The simplified form of sudoku.
The traditional form of sudoku
This version of sudoku is designed to run on a telnet screen. You can also run it on your local Linux console or an xterm window in X Windows.
The rules for playing the game in this program are the same as the standard rules. The program gives you error messages when a duplicate number is entered, or when you try to enter a number over an original number on the card.
This version of sudoku is similar to solitaire. Not every card can be completely filled in. The purpose of this game is to see how many numbers (1-9) you can fill in in the shortest time possible with the fewest errors.
To start sudoku, run the command,
sudoku
Use the arrow keys to move the cursor. The cursor jumps over original numbers on the card.
Press the letter b to replay the
same game. You may replay the same game
at any time.
Press the letter r to reset to a
new game. You may reset the game at any time.
Press the letter q to quit the game.
You may quit the game at any time.
sudoku shows the menu on the left
of the screen. On the right of the screen,
is the sudoku card. The number with reverse
video is where the cursor is pointing. If
you enter a number on your keyboard, this
number should change, unless it is in error.
Below the menu on the left is a running
count of elapsed time in minutes and
seconds. Below this is the total number
of errors in the current game.
sudoku writes to a log file in the
local directory, called
sudoku.log.
This file is replaced every time you start
or reset the game. The
replay option extends the log.
The log shows the initial card and the final
card and the time stamp for each. Below
the final card is the number of numbers entered
and the number of errors.
sudoku sleeps in between key strokes to
allow other tasks to run during the game.
