What Is Warmle? The Hot-and-Cold Wordle Game Explained

Warmle is a Wordle spin-off with a hot-and-cold twist — a daily word puzzle where yellow tiles reveal when your guessed letter is within three places of the correct letter alphabetically, instead of only telling you whether a letter is in the word. You get five guesses to track down the hidden five-letter word, guided by a thermometer that shows your progress. This alphabet-guessing game turns every round into a logic exercise.

What Is Warmle?

Warmle (playable at warmle.org) keeps Wordle's core — guess the hidden five-letter word — but replaces the standard yellow clue with something far more informative. In Wordle, yellow means "right letter, wrong spot." In Warmle, yellow means "this letter is close alphabetically": the correct letter sits within three positions of your guess in the alphabet (wordhurdle.co).

The game is free, runs in the browser, and gives you one puzzle per day — a hot-and-cold word game that trades Wordle's letter-position clues for alphabet-proximity clues, making it a favourite wordle variant for players who like their daily word game with extra logic.

How to Play Warmle: The Rules

You have five attempts to guess the hidden five-letter word. After each guess, every tile is coloured:

• Green — the letter is exactly correct. Lock it in and keep it.
• Yellow — the letter is not correct, but the true letter is within three places of it alphabetically. For example, if you guess D and the answer's letter is F, the tile turns yellow.
• Grey — the true letter is more than three places away in the alphabet, so your guess was "cold."

A thermometer at the bottom of the screen acts as a progress indicator: it shows how many words in the dictionary you have ruled out so far based on your clues, letting you watch your search space shrink with every guess (wordhurdle.co).

Worked example

Suppose the hidden word is MERRY and your first guess is CRANE:

• C vs M: 10 places apart → grey (cold).
• R vs E: 13 apart → grey.
• A vs R: 17 apart → grey.
• N vs R: 4 apart → grey — just outside the yellow zone.
• E vs Y: 20 apart → grey.

A frosty start — but a useful one, because you have eliminated wide alphabet ranges in every column. A smarter second guess like MIGHT probes the middle of the alphabet: M vs M goes green immediately, and the remaining feedback brackets nearby letters into tight yellow windows. That bracketing power is what makes Warmle strategically richer than it first appears.

Warmle also ships with an Unlimited practice mode alongside the daily puzzle, so you can drill the alphabet-bracketing technique as much as you like — the unlimited word game option is a big reason strategy-minded players stick with it.

Strategies and Tips for Warmle

These tactics build on general word puzzle strategies, adapted for Warmle's alphabet-clue system:

Think in alphabet positions, not just letters

The key mental shift: A=1, B=2, all the way to Z=26. A yellow tile on your guessed letter means the answer's letter lies in a plus-or-minus-three window around it. Jot down the candidate letters for each yellow tile before guessing again.

Open with alphabet-spread starters

Because yellows give ranges rather than exact hits, first guesses with letters spread across the alphabet — mixing early, middle and late letters — map the territory fastest. Avoid clustering your opener's letters together.

Binary-search the alphabet

When a column goes grey, the answer's letter is far away, so jump to the opposite end of the alphabet in your next guess. When it goes yellow, you have trapped the letter inside a seven-letter window; probe the middle of that window next.

Watch the thermometer

Glance at the thermometer after each guess. If it barely moves, your guess overlapped too much with previous ones — pick a word that tests entirely new alphabet territory instead.

Narrow yellows systematically

A yellow tile leaves up to seven candidate letters. Combine it with your other columns' constraints and the remaining dictionary shown by the thermometer to choose the single most informative next word.

Remember it is still five letters

All of your Wordle word knowledge transfers directly: common five-letter patterns, frequent endings and vowel-placement instincts all still apply — Warmle only changes what the colours tell you.

Do not ignore double letters

Like Wordle, Warmle answers can repeat letters. If a column gives conflicting signals across guesses, consider that the answer may contain the same letter twice.

Play the alphabet edges on guess two

If your opener returns all grey, your second guess should live at the opposite ends of the alphabet from your first. Warmle punishes timid, overlapping guesses more than Wordle does — the thermometer rewards bold repositioning.

Common Warmle Mistakes

1. Treating yellow like Wordle's yellow — the most common beginner error. In Wordle, yellow means "right letter, wrong spot." In Warmle, it means the true letter is within three alphabet places of your guess. Reading it the Wordle way throws off every later guess.
2. Overlapping your guesses — if the thermometer barely moves after a guess, you re-tested alphabet territory you already covered. Pick a word that probes entirely new regions instead.
3. Ignoring the thermometer — it shows how many dictionary words your clues have eliminated. Glancing at it after each guess keeps you honest about whether you're actually making progress.
4. Forgetting double letters — like Wordle, Warmle answers can repeat letters. If a column gives conflicting signals across guesses, consider that the same letter appears twice.
5. Clustering your opener — letters bunched together in the alphabet map less territory. Spread your first guess across early, middle, and late letters to maximise the bracketing information.
