What each role does during a round

At the start of a round, the site selects one topic card. Every player can see the question on the front and any player-facing directions that belong to its card shape. On tagged cards, one direction is connected to the answer and two are plausible alternatives. The directions give players places to begin without stating which one is correct.

The current Thinker is public, so the group knows who will make the guess. Every other role remains private on the player who received it. A shared screen is unnecessary because each phone or browser receives the view intended for that player.

• Question and any player-facing directions are visible to everyone.
• The Thinker is public.
• The Truth-Knower remains private until the reveal.

The Thinker does not receive the answer. During discussion, the Thinker listens to the explanations given by the other players and may ask follow-up questions. When the guessing phase begins, the Thinker selects one other player as the person believed to know the answer.

The Thinker cannot choose themselves. If a guessing timer is enabled, the selection must be made before it ends. With timers off, the host advances the round when the group is ready. The chosen player and the result are then recorded by the site.

The Truth-Knower is the only player who can open the back of the topic card before discussion. The back contains the answer in the edition chosen for the room, either full or short. When discussion begins, the card returns to its front for every player.

The Truth-Knower explains the topic in their own words while trying not to make the role immediately obvious. The content should remain consistent with the card. The role is revealed after the Thinker has submitted a guess.

All remaining players are Bluffers. They see the same question and any player-facing directions as the Thinker but never receive the answer. Their task is to give an explanation that could fit the question and respond when the Thinker or another player asks for more detail.

On a tagged card, a Bluffer may begin from any of the three directions; on an open card, they start from the shared subject and its unusual property. Nothing is entered into a form during discussion. The conversation takes place among the players, in person or through their chosen voice call.

The game does not enforce a speaking order. A group may let each non-Thinker speak once before open questions, or it may begin with free discussion. Optional room timers can limit the card-view, discussion, and guessing phases, and all three timers are off by default.

When discussion ends, the Thinker chooses a player. The site accepts one selection and moves the round to reveal and scoring. Other players do not vote, and no one needs to type an explanation into the website.

Scoring uses the card difficulty D, from 1 to 3. A correct guess gives D points to both the Thinker and the Truth-Knower. An incorrect guess gives D points to the selected player. If the guessing timer expires without an answer, the Thinker loses D points. A once-per-card 收皮啦 callout gives the Thinker +1 and the target −1 when aimed at a Bluffer, or gives the Thinker −3 when aimed at the Truth-Knower.

Each player can first read the revealed answer and then continue to the scoreboard. The host alone starts the next round, and the new round replaces the result view on every device. In a new room, the first Thinker is random and later turns follow the opening join order; the number of rounds equals that opening roster. Older room snapshots keep their stored rules.
