  • Typing H while the cursor is on a number, e.g. 2, will highlight all the 2s in the matrix.

    Typing H again will undo the highlighting:

-Typing E and entering up to 3 digits, will earmark the cell:

  • Entering an illegal number (a number that already exists in the row, the line or the 3x3 block) will mark the number with a different color, and give a warning message:

While the Moption returns to the Main Menu, and the S option saves the game, the Q option prints the solution and exits:

  • This is neat. I am going to put it on some production servers, because why not...

    Edit: Poop. Renders a bit funny over a putty session.

    • I see no numbers in the 9x9 matrix, have you installed the qqwing dependency?

      https://qqwing.com/download.html

      On Debian based distros:

      sudo apt install qqwing fzf lolcat

      • Ah, yes. I should read instructions...

        This server is CentOS so I will see where I can get those packages

        • You should πŸ˜€

          The page I sent you (you should read that too, btwπŸ˜€) has you covered I think, describes download instructions for many distros.

          fzf and lolcat are quite easy to install I think.

          • Yeah, I ran into a further dependency issue with qqwing regarding gcc so I will take a dive when I have a bit of spare time. Thanks though.
