There is one secret word each day. Guess any English word and you'll see how close it is in meaning — not spelling.
Temperature is how similar your word is to the secret, up to 100° for the word itself.
The 1,000 words closest to the secret get a rank: #1 is the nearest, #1000 is just warm. Anything outside the top thousand is cool, cold or frozen.
Stuck? Hint reveals a word warmer than your best. The meaning map comes from how words appear together in millions of texts, so some neighbours will surprise you.
