Wordle is an elegant (and addictive) word-guessing game.
The rules are simple. You have six attempts to guess a 5 letter word. With each attempt you are shown clues as to whether your letters are in the right place or if they’re not used at all (kind of like hangman).
The crucial mechanic is scarcity: there’s only one word a day, and everybody gets shown the same word… which instantly makes it a competitive social game despite having no in-built league table or multiplayer.
