How to play

Last updated: 2026-07-25

Hot & Cold is a free word-guessing game where every guess is judged by meaning, not spelling. There's a secret word, and each word you type comes back with a temperature: ๐ŸงŠ freezing if it lives in a completely different corner of the language, ๐Ÿ”ฅ blazing if you're circling the answer. You play it on the web, iOS, or Android, and a round takes anywhere from two minutes to one very stubborn lunch break. This page explains everything the game measures and how it scores you โ€” if you just want opening strategy, jump to the tips page.

The goal

Find the secret word. That's it โ€” no grid, no letters turning green. You type any word you like, and the game tells you how close that word is in meaning to the secret. Guess again, get warmer or colder, and narrow the field until you land on the word itself. Your first few guesses are free, and wild swings early on barely cost anything; the whole first phase of a round is about figuring out which neighborhood of ideas the secret lives in.

Not every word is a legal guess. Entries are checked against a fixed dictionary of 14,828 words, nearly all of them everyday nouns in their simplest one-word form. Anything shaped differently โ€” a plural or a verb, a proper name, a hyphenated rarity โ€” gets turned away unscored (the FAQ explains the reasoning). And only the roughly 6,500 most familiar words on that list can ever be the secret, so the answer is always something you actually know โ€” never an obscure trivia term.

How heat and rank work

Behind the scenes, every word on the list has a position in a map of meaning built from 1,024-dimensional word embeddings โ€” the same kind of representation modern language models use. When a round starts, all 14,828 words are ranked by how similar they are to the secret. Rank #1 is the secret itself; rank #2 is its closest neighbor in meaning, and so on down to the most distant word on the list. Every guess you make shows you its rank, and the rankings are deterministic: two players who guess the same word against the same secret always see the identical number.

Rank is then translated into a heat bucket, from coldest to hottest:

The bands are log-scaled, so each step up the ladder is a much bigger deal than the last (exact boundaries adapt to the list size, which is why the numbers above say "roughly"). In practice: hot means the secret is probably a sibling of your guess โ€” same category, related concept โ€” and it's time to start guessing specific neighbors. Blazing means you should slow down and think, because the answer is likely a synonym, a near-twin, or something your guess is literally a part of. And don't be discouraged by a wall of freezing early on: with almost fifteen thousand words on the list, the vast majority are freezing for any given secret. Cold answers still carry information โ€” they tell you which parts of the map to stop searching.

A worked example

Here's an invented example round โ€” the secret is violin, and the ranks below are illustrative, not pulled from a live puzzle. It shows how a typical solve actually feels:

  1. river โ€” rank #8,142 ๐Ÿฅถ freezing
  2. sound โ€” rank #98 โ˜€๏ธ warm
  3. wood โ€” rank #1,412 ๐ŸŒจ๏ธ cold
  4. music โ€” rank #16 ๐ŸŒถ๏ธ hot
  5. trumpet โ€” rank #21 ๐ŸŒถ๏ธ hot
  6. orchestra โ€” rank #9 ๐Ÿฅต hot
  7. guitar โ€” rank #4 ๐ŸŒ‹ blazing
  8. violin โ€” rank #1 ๐ŸŽฏ solved

The reasoning between guesses is where the game lives. river was a shot in the dark and came back freezing โ€” fine, that rules out the whole outdoors. sound landed warm at #98, a real signal: the secret has something to do with audio. wood tested a different angle โ€” materials โ€” and came back cold, far behind sound, so that thread got dropped (a small irony, given the answer, but the game measures overall meaning: "wood" is mostly about trees and lumber, only faintly about instruments). Doubling down on the audio signal, music hit hot at #16 โ€” huge jump, the secret is music-adjacent. trumpet probed whether it was an instrument: hot at #21, so yes, an instrument, but apparently not a brass one. orchestra climbed to #9 โ€” orchestral, then โ€” and guitar went blazing at #4, all but naming it: a string instrument, orchestral, and not a guitar. From there, violin was the natural next word. Eight guesses, one solve, and every guess โ€” even the freezing one โ€” narrowed the space.

Hints

Stuck? Tapping Hint reveals a cluster of three clue words that sit adjacent in the ranking: the hint word plus its neighbors just above and below. Seeing three related words at once tells you far more about the secret's neighborhood than any single word could.

Hints come in tiers that get progressively closer to the answer. Your first hint lands somewhere around rank 101โ€“500, the second around 21โ€“100, and the third around 10โ€“20. Those tiers are also the cap: every mode allows at most 3 reveals per round. Hints are an on/off switch, not a dial โ€” the host's call for a Challenge room, yours in Endless settings โ€” and whenever they're on, the same three tiers apply.

Each cluster is charged once against your round score, and the cost is proportional to how much it actually helped: the penalty scales with how far the hint advanced you past your best guess so far, capped at 150 points. Take a hint early with nothing on the board and you pay near the full 150; take one when you're already blazing and it costs very little; a hint that's no better than your best guess is free. One ordering rule to know: if you already guessed a word that later shows up inside a hint cluster, your guess keeps its rank and the cluster adds nothing for it โ€” but you can't guess a word after it has been revealed as a hint. When in doubt, guess first, peek second.

Scoring

Every round is scored out of 1,000 points. A win starts at 1,000 and loses points for guesses, hints, and โ€” in timed rounds โ€” elapsed time. Your first 4 guesses are free, and after that the guess penalty grows on a logarithmic curve, so a handful of extra guesses barely dents your score while a marathon slowly drains it. For a hint-free win, the totals land approximately here:

Rounds with a countdown timer use time mode instead: elapsed seconds are converted into equivalent guesses at about 4 seconds per guess, then the same curve applies โ€” so thinking fast matters exactly as much as guessing efficiently.

If you give up, you keep partial credit of up to 250 points based on the best rank you reached โ€” the closer you got, the more you keep, minus any hints you took. A win, meanwhile, is always floored at 250 points, so solving the puzzle always outscores surrendering, no matter how long it took. Giving up isn't a dead end, though: it reveals the secret plus the top 100 closest words (top 50 in Challenge), which is one of the best ways to learn how the game "thinks" about meaning.

The three modes

Daily gives everyone in the world the same secret, changing at 00:00 UTC, with streaks for consecutive days and an optional global leaderboard. Endless is unlimited practice with a fresh random secret each round and per-round settings for hints, letter count, and a timer. Challenge is async multiplayer: share a link, everyone in the room plays the same secret, and rounds award podium-style points that accumulate across a series. The homepage has a card for each mode, and the FAQ covers the fine print โ€” guess caps, streak timing, and offline play on iOS and Android.
