Wordle, a cross between Mastermind and Hangman, seems to be the rage these days. Also, implementing it in as few lines as possible. In Logo we get to cheat a little about the second bit, as we can stack multiple commands on the same line. But we still need to keep things within a reasonable line length.
We’re happy to say we succeeded in our efforts, and even expanded on the model somewhat, adding progressively longer words and hints, among other things. This is a pretty good example of string and list management in Logo, which is what it was initially created for, even before the turtle!
