Rounds

How it works

  1. 1

    Everyone fakes a definition

    A real but ridiculously obscure word appears — like "petrichor" or "snollygoster". Each player secretly writes a definition that sounds like it came straight out of the dictionary.

  2. 2

    Spot the true meaning

    All the fake definitions are shuffled together with the real one. Can you tell genuine etymology from your friends' confident nonsense?

  3. 3

    Score for smarts and trickery

    Earn 1000 points for finding the real definition, plus 500 for every friend who believes your fake. The reveal shows the word's true story — and who fooled whom.

Sample rounds

What a Guess the Definition round looks like

Three real words, the definitions players invented for them, and a reveal that names who fell for what. All of this is in the page you are reading, so you can see the loop before you open a room.

Aglet

Real meaning: The plastic tip on the end of a shoelace.

  • Invented definition: A trainee blacksmith
  • Invented definition: The gap between two roof tiles
  • Invented definition: A very small medieval coin

Sample reveal: Priya knew this one and banked the 1000 for finding it. Ben's blacksmith answer fooled three people, so he finished the round ahead of her.

Borborygmus

Real meaning: The rumbling sound a hungry stomach makes.

  • Invented definition: A rolling drum used in a procession
  • Invented definition: A fear of crowded rooms
  • Invented definition: The echo inside a long tunnel

Sample reveal: nobody found the truth. Maya's drum definition swept the room, and the group refused to believe the real answer until the etymology came up.

Interrobang

Real meaning: A punctuation mark that combines a question mark and an exclamation point.

  • Invented definition: A knot that tightens under load
  • Invented definition: A jackdaw's alarm call
  • Invented definition: The pattern frost leaves on glass

Sample reveal: Sam wrote the frost answer, watched two people pick it, and then had to admit the real meaning was better than the lie.

Best for

Who should start with Guess the Definition?

Groups who argue about words

Best with 4 to 6 players who will defend an invented etymology with a completely straight face and then get held to it at the reveal.

Classrooms and book clubs

Everyone writes at the same time, so nobody is put on the spot, and the round ends with a real word and where it came from.

Video calls and quiet warmups

The writing phase is typed rather than spoken, which makes this one of the easier games to run over a call with a group that has not met before.

Why it's fun

🎓 Confidence beats knowledge

Nobody actually knows what a "zarf" is — so the win goes to whoever writes the most dictionary-sounding nonsense. Bluffing skills outscore vocabulary every time.

📖 You accidentally learn words

Every reveal tells the word's real story — the etymology, the history, the weird usage. You'll leave the game with insults and party facts nobody saw coming.

Frequently asked questions

Is the definition game free to play online?
Yes. Guess the Definition runs free in the browser at PartyRoomGames: open a room, send the code, and start when everyone has arrived. Nothing is installed and no card set is bought.
How many players do you need?
2 to 100 players per room. More players means more fake definitions to sift through — 4 to 6 is the sweet spot.
Do I need a big vocabulary to win?
Not at all — the words are obscure on purpose, so almost nobody knows them. Sounding convincing matters far more than being right.
Does anyone need an account to join?
No. Guests pick a nickname, type the room code, and are in. Only the person who opened the room needs to press start, so a group can be writing on their own phones about a minute after the link goes out.
How long does one online game last?
Under eight minutes for five rounds at the default timers, and usually faster: each phase ends the moment everybody has answered instead of running the clock down. A rematch starts the scores fresh.
Does it work on a phone?
Yes, and mixed rooms are normal — one player on a laptop, three on phones. Writing a definition is the only typing anybody does, so a small keyboard is no handicap.
What kind of words come up?
Real entries almost nobody uses: the tip of a shoelace, the noise an empty stomach makes, the punctuation mark invented for excited questions. Nothing needs specialist knowledge, and every reveal ends with where the word came from.
