NAME

       nudoku - ncurses based sudoku game

SYNOPSIS

       nudoku [OPTIONS]

DESCRIPTION

       nudoku  is  a ncurses based sudoku game. Perfect to relax a little or just waste some time
       when you are on the console.

Keybindings

       For navigation use vi-keybindings (hjkl) or arrow keys.  Pressing a number will put it  in
       a field. Pressing delete, backspace or x will delete it.

       Some keys need to be typed uppercase to prevent pressing them accidentally.

       c  Gives  feedback  whether  your solution is right. If you think you finished your sudoku
       press this key to make sure it is. You can also use this during the game to check  if  you
       have made any mistakes.

       H  The  computer  will fill in one number for you. If you are pretty close to finishing he
       might not want to help you.  And if you did something  wrong  so  far,  he  will  not  say
       anything.

       m  Toggle marks. If enabled, the number in the currently selected cell will be highlighted
       in all other cells they occur in.  Only works when colors are enabled.

       N Create a new puzzle.

       Q Quit nudoku.

       r Redraw screen. In case you resized your terminal this will come handy.

       S Let the computer solve the puzzle.
