Transcript

Questions and answers.

Turns are shown in the order they happened. Each shows the Guesser's question or guess, then the final checked answer.

Exact Guesser setupSystem message and BEGIN event

The Guesser received these messages at the start of the round. The BEGIN message holds the broad category and a code made from the base seed and round number, which reveals nothing about the subject.

System message
You are the Guesser in a Twenty Questions benchmark. Identify the hidden subject using as few
counted turns as possible. BEGIN provides only its broad category. The variation_token has no
clues; do not interpret, mention, or repeat it.

The category in BEGIN has a broad meaning:
- person: a real human, living or historical.
- fictional_character: an invented character from a story, book, comic, film, television,
  game, or another fictional work.
- mythological_figure: a figure from mythology or traditional legend.
- video_game_character: a character known from video games.
- thing: a broad category covering natural and human-made entities, living or nonliving,
  whole entities or parts of them. Possibilities include everyday objects, tools, machines,
  materials, food, animals, plants, body parts, natural structures, geographical features,
  celestial bodies, natural phenomena, and concepts. These possibilities are not exhaustive.
  The target may be a general kind or one particular instance.

Use questions to narrow the supplied category. These definitions are not a list of targets.

Use ASK for a factual question that distinguishes candidates. Never use ASK to confirm a
specific identity. Use GUESS with a name and short identifying description to name a candidate.

ASK has five possible replies:
- YES or NO: the evidence establishes that answer to the exact question.
- RATHER_YES or RATHER_NO: evidence leans that way, but is not strong enough for a firm answer.
  Treat this as a clue; keep candidates fitting the opposite answer possible.
- UNKNOWN: no reliable direction. It supports neither answer.

Ask clear questions about verifiable properties. "Can", "sometimes", "usually", "always", and
"mainly" ask different things. Do not assume that one property proves another or rules out alternatives.
Qualified replies express uncertainty about your question, not how often a property applies.
Before narrowing heavily, check your key assumption with a different property. After rejected
guesses, reconsider earlier assumptions as well as candidates. Answers can be mistaken; check
another property when stuck. Do not ignore an answer merely because it conflicts with a
preferred candidate.

Each ASK, rejected GUESS, or format error before the limit costs one turn. A correct GUESS costs
none. After 40 counted turns, make one final GUESS; ASK is then forbidden. Identity
validation uses only YES, NO, or UNKNOWN. UNKNOWN on GUESS ends the game without success.

FORMAT_ERROR means your output broke the contract, was not checked for correctness, and cost
one turn. Retry using its displayed formats if a turn remains. Return only the required JSON
object with exactly one result action. No explanations, reasoning, or extra fields.
BEGIN event
{"category":"thing","event":"BEGIN","variation_token":"EAQCORIU"}

Valid replies are shown in the required format. Rejected replies are shown separately, without provider or call IDs.

3 of 33 answers in this round reuse an earlier, fully checked answer with its original evidence. No new search or check ran for those turns.
