Morsle is a daily Morse code puzzle. You hear a word in Morse code and try to type it, with correct letters marked in green when they are in the right positions. The audio starts at 40 words per minute and slows by 5 WPM every three attempts. You have 21 guesses to solve the word before the answer is revealed.

Green letters mark correct positions in your guess. No other clues are given—no yellow tiles, no letter counts, no hints about nearby letters. The playback begins at 40 WPM and drops to 35 WPM after attempt three, 30 WPM after attempt six, and so on until the final rounds play at a slower, more readable pace.

Tips for decoding efficiently

You have 21 attempts across a range of speeds. Early guesses at 40 WPM may catch only fragments, so consider using those rounds to test common letter patterns or word shapes rather than random tries. Once green letters appear, build around them instead of ignoring confirmed positions.

Playback speed matters. If 40 WPM is too fast to parse individual letters, wait a few attempts until the code slows to a range where you can distinguish dits and dahs reliably. Spending early attempts on partial information can still narrow the word structure for later rounds.

Because one guess follows each listen, avoid submitting before you have processed the full sequence. Morse rhythm can reveal word length and letter boundaries, so let the audio finish before typing.
