The Chameleon

Everyone except one player can decode the secret word. Say enough to prove you know it, but not enough to teach it to the Chameleon.

How to play The Chameleon

Goal
Code-card players must identify the Chameleon without revealing the secret word. The Chameleon must avoid the vote or infer the word after being caught.
Set up
Shuffle one Chameleon card into a matching set of code cards and deal one facedown to each player. Reveal a topic card and roll both dice; their coordinates identify the secret word for everyone with a code card.
Play
Starting with the dealer, each player says one word related to the secret word. After every clue, discuss who sounded uninformed and vote simultaneously for the suspected Chameleon.
Finish
If the table exposes a code-card player, the Chameleon escapes. If the Chameleon is exposed, they get one guess at the secret word and escape if correct. Optional scoring ends when one player reaches five points.
Easy to miss
The dealer breaks a tied vote. With three players, give a caught Chameleon two guesses. With seven or eight, turn the topic card facedown after all clues and before discussion.

One word, except for one person

A topic card shows a grid of possible words. Two dice produce coordinates, and each code card translates those coordinates into one secret word. Everybody with a code card can find it. The Chameleon cannot.

Going around the table, each person gives exactly one related word. A clue can fail in either direction. Too vague and you sound lost. Too specific and the Chameleon may learn the answer in time to steal the round.

The Chameleon listens and tries to sound informed. If everybody else has already explained the word, their job gets much easier.

A clue is evidence

Suppose the topic is office supplies and the secret word is stapler. "Metal" may be true but unhelpfully broad. "Corner" could establish knowledge without naming the object. "Fastener" may prove too much, especially if the Chameleon speaks late and has heard every clue before choosing one.

Turn order changes the risk. Early players have little evidence to work from. Later players hear more clues but have fewer unused ideas. The official rules allow the Chameleon to repeat somebody else's clue, though copying does not necessarily make anyone look innocent.

After the word is decoded, give everybody a quiet moment to think. Then take the clues in order without interruption. Save the debate for the end. If players cross-examine each clue as it arrives, the later players get a tutorial.

Point, vote, reveal

Once every clue is in, the table discusses who seems least connected to the secret. Everyone then points to one suspect. The player with the most votes reveals their card, and the dealer breaks a tie.

If an ordinary code card is exposed, the Chameleon escapes. Catch the Chameleon and they still get one chance to name the secret word. A correct guess steals the round.

That final guess is why the other players cannot give increasingly obvious clues. They need enough information to recognize one another without spelling out the answer.

Optional scoring gives an undetected Chameleon two points, a caught Chameleon who guesses correctly one point, and every other player two points when the Chameleon is caught and misses. First to five wins. The game also works as a sequence of standalone rounds if nobody wants to keep score.

The player-count rules matter

The current product supports 3 to 8 players.

At three, a caught Chameleon gets two guesses at the secret word. With only two real clues on the table, being identified is easier and reconstructing the answer is harder.

At seven or eight, turn the topic card facedown after everyone has given a clue. The Chameleon may still reason from what was said, but cannot keep scanning the full grid during the debate.

The linked Big Potato rule sheet covers the original edition and supports the scoring and player-count variants above. Big Potato's current shop features a newer edition, so check the rule sheet inside that box for edition-specific component counts and wording.

Make sure the room wants the accusation

Each player only says one word. Most of the game is spent deciding what those words prove. One person is bluffing, and a weak clue can become the whole case.

This works for a group that enjoys bluffing but does not want the longer roles and night phases of a large social-deduction game. It is a worse fit for players who dislike lying, public accusations, or improvising a clue while people watch.

Before opening the box, tell the room that every round ends with a public suspect and a pointed finger. If being confidently wrong about a friend sounds like a good evening, the rest of the pitch is already done.
