How to play

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: 🧊 freezing if it lives in a completely different corner of the language, 🔥 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.

The short version

• Type any everyday noun. There's no grid and no letters to match.
• Each guess comes back with a rank and a heat emoji. Rank #1 is the secret, so lower is hotter.
• Chase the heat. When a guess runs warmer, keep pulling that thread. When it cools, try a different idea.
• Stuck? Help sells word hints and letter reveals for points.
• Solve it to win. Rounds are scored out of 1,000.

That's the whole game. The rest of this page is the detail behind it: what the ranks mean, what help costs, and how a round is scored. For opening strategy instead, jump to the tips page.

The goal

Find the secret word. That's it: 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 working out which neighborhood of ideas the secret lives in.

Not every word is a legal guess. Entries are checked against a fixed dictionary of about 15,000 words, every one of them a word that can be a noun. Anything that can't gets turned away unscored: adverbs, proper names, hyphenated rarities (the FAQ explains the reasoning). Plurals are the exception: cats scores as cat. And only the most familiar words on that list can ever be the secret, so the answer is always something you actually know rather than 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 we build ourselves, from which words keep company with which across a huge body of text. When a round starts, the whole list is ranked by how similar each word is 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:

• 🥶 🧊 Freezing: roughly rank 3,000 and beyond. Most of the list lives here.
• ❄️ 🌨️ 🌧️ Cold: roughly the top 3,000. Distant, but no longer the outer wilderness.
• ☁️ ⛅ 🌤️ Cool: roughly the top 600. A loose thematic connection is showing up.
• ☀️ 💦 Warm: roughly the top 120. You've found the right neighborhood.
• 🌶️ 🥵 Hot: roughly the top 24. Close relatives of the secret start showing up here.
• 🌋 🔥 Blazing: ranks 2–6. You're a word or two away from the answer.
• 🎯 Solved: rank #1, the secret itself.

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, something in the same category or a closely related concept, 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, since they tell you which parts of the map to stop searching.

A worked example

Here's an invented example round. The secret is violin, and the ranks below are illustrative rather than pulled from a live puzzle. It shows how a typical solve actually feels:

1. river: rank #8,142 🥶 freezing
2. sound: rank #98 ☀️ warm
3. wood: rank #1,412 🌨️ cold
4. music: rank #16 🌶️ hot
5. trumpet: rank #21 🌶️ hot
6. orchestra: rank #9 🥵 hot
7. guitar: rank #4 🌋 blazing
8. violin: rank #1 🎯 solved

The reasoning between guesses is the game. river was a shot in the dark and came back freezing, which at least 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, materials, 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. That's a huge jump, so 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, so orchestral, and then 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 narrowed the space, including the freezing one.

Getting help

Stuck? The Help button during a round offers two different kinds of assistance, and every row shows its price in points before you commit to it. Nothing is bought by accident.

Word hints

A hint reveals a cluster of three clue words that sit together in the ranking: the hint word plus its nearest neighbors. 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 101–500, the second around 21–100, and the third around 10–20. Those tiers are also the cap: every mode allows at most 3 hints per round.

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, and 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. What you can't do is guess a word after it has been revealed as a hint. When in doubt, guess first and peek second.

Letter reveals

Two one-off purchases that tell you something about the word's spelling rather than its meaning:

• Letter count: how many letters the secret has. Costs 75 points.
• First letter: the letter it starts with. Costs 125 points.

Buy either, both (200 points), or neither, in whichever order you like. They don't use up any of your 3 hints, and unlike hints the price is flat: it never changes with the answer, with how far along you are, or with how much the reveal happens to narrow things down. A price that moved would itself be a clue, given away before you paid for it. If the round was set up to show the letter count for free, that row simply isn't for sale.

These are best thought of as an endgame filter rather than a direction finder. Knowing the secret has eleven letters won't tell you where to look, but it will cross most of a shortlist off in one go. In Challenge rooms a reveal is yours alone: nothing about it is sent to the other players. Team rounds are the exception and don't offer them at all, since a team shares one board and one score, so the cost would come out of everyone's round.

Whether a round offers help at all is set before it starts: a Challenge host decides for the room, and you decide in Endless settings. Hints, the letter count reveal and the first letter reveal each have their own switch under it, so a round can offer all of them, just the hints, one reveal and not the other, or nothing at all. Switching help off closes the whole menu.

Scoring

Every round is scored out of 1,000 points. A win starts at 1,000 and loses points for guesses, hints, and (in timed rounds) 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:

• 10 guesses ≈ 947 points
• 20 guesses ≈ 841 points
• 50 guesses ≈ 643 points
• 100 guesses ≈ 447 points
• ~330 guesses → 0 from guess penalties (the win floor below still applies)

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, 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. 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 help, a free letter count, and a timer. Challenge is multiplayer: share a link, everyone in the room plays the same secret, and rounds award podium-style points that accumulate across a series. Play it together when you're all around, or join a round that's already running and catch up. A challenge room can also run in cooperative team mode, where 2–4 teams each share a single board and solve the word together, and every online room has chat with a spoiler-safe channel for players who have finished. The homepage has a card for each mode, and the FAQ covers the fine print on guess caps, streak timing, and offline play on iOS and Android.

Quick-reference tips

• Open broad. Category words like animal, machine, food, or music sweep large regions of meaning with a single guess.
• Ride your hottest word. Once something turns hot, guess its synonyms, siblings, and parts rather than starting a new theme.
• Cold is information. A freezing guess eliminates an entire neighborhood, which counts as progress rather than failure.
• Think meaning, not spelling. guitar is close to violin because of what it is, not because they share letters.
