lewdle (as well as the original Wordle) is a brainteaser that falls between between a crossword puzzle and a sudoku puzzle. The principle of Wordle will be instantly apparent to anyone who has played the game Mastermind, which uses colored pegs.

The goal of Wordle is to guess the hidden word in six tries, using a sequence of suggestions to do so; the goal of Lewdle is the same, but instead of normal words, all of the words are nasty.
