Frequently Asked Questions
Everything you need to know about Hot & Cold
Getting Started
What is Hot & Cold?
A free daily word game where you discover a secret word by typing guesses. Instead of checking letters like Wordle, the game measures how close your guess is in meaning to the target using AI-powered semantic similarity. Each guess gets a rank and a temperature label — the hotter you are, the closer your word is to the secret.
How do I play?
Type any English word into the guess box on the homepage and press Enter. You’ll get a rank number and a hot-or-cold indicator. A lower rank means your guess is closer in meaning to the secret word. Keep refining based on the feedback until you reach rank #1.
Is it free to play?
Yes, completely free. No account or payment needed to start guessing. The game runs in your browser on any device — phone, tablet, or desktop. Signing in with Google is optional and lets you save your stats across devices.
Do I need an account to play?
No. You can play as a guest immediately. Your progress for the current challenge is saved locally in your browser. If you want to preserve your stats, streaks, and history across devices, you can sign in with your Google account at any time.
Gameplay
How does the ranking system work?
When you submit a guess, the game compares your word to the secret word using a semantic similarity model. It then ranks your guess among all words in its vocabulary. Rank #1 is the secret word itself. A rank of #500 means there are 499 words that are more similar to the secret word than your guess. The lower the rank, the closer you are.
What does 'hot' and 'cold' mean in the game?
The temperature labels are a quick visual summary of your rank. 'Hot' or 'very hot' means your guess is among the closest words to the secret word. 'Warm' means you are in the right general area. 'Cold' or 'very cold' means your guess is far from the target. A color gradient bar also shows your position visually.
How many guesses can I make?
There is no limit on the number of guesses. You can make as many guesses as you need to find the secret word. However, your final score is partly based on how few guesses you needed, so efficiency is rewarded.
How do hints work?
If you are stuck, you can request a hint. The game offers up to three hint tiers per challenge. Each hint reveals a word that is semantically close to the secret word, helping you narrow down the right area. Using hints may affect your final score, so use them strategically.
What happens if I give up?
If you choose to give up, the secret word is revealed so you can learn from it. Your challenge is marked as 'given up' in your history. You can still explore past challenges in the archive to practice without pressure.
When does the daily word update?
A new secret word is released every day at midnight UTC. All players around the world play the same word on the same day. Once the day resets, the previous challenge moves to the archive where you can replay it at any time.
Strategy
What are good starting words?
Start with broad category words: animal, food, place, technology, emotion, music. These help you quickly identify which area of meaning the secret word belongs to. Once you find a warm category, narrow down with more specific words.
How is this different from Wordle?
Wordle is a letter-position game: you get green and yellow tiles based on which letters are correct. Hot & Cold is a meaning game: you get a similarity rank based on how close your guess is in meaning to the secret word. You can guess any English word of any length, and the feedback is about semantics, not spelling.
Why do similar-sounding words sometimes rank far apart?
The game uses semantic similarity, not phonetic or visual similarity. Words that sound or look alike (such as 'bear' and 'bare') can have very different meanings and therefore very different ranks. The AI model groups words by how they are used in context, not by how they sound or are spelled.
Can I play past challenges?
Yes. Visit the archive page to browse and replay past daily challenges. This is a great way to practice your strategy without the pressure of the daily timer. The archive shows up to 30 recent challenges with your completion status for each one.

How is my score calculated?
Your score is based on the number of guesses you needed to find the secret word, whether you used any hints, and how quickly you narrowed down the answer. Fewer guesses and no hints result in a higher score. The exact formula rewards both efficiency and skill.
