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.

OPTIONS

       -h Print help.

       -v Display version information.
