Wordle offers an optional Hard Mode accessible via the in-game settings gear. Understanding the difference is vital for competitive players: Wordle Today
Regular Mode: Players can enter any valid five-letter word at any time, even if it ignores previous clues. This flexibility allows for the strategic "sacrifice word" method mentioned above to eliminate pesky letters.
Hard Mode: Any revealed hints must be used in all subsequent guesses. If a letter turns green or yellow, your next attempt is strictly required to incorporate it. Hard Mode prevents brute-force letter burning, demanding pure deductive logic.
