Asked with: Mysterium Parkbg-301767-en-1e

Mysterium Park is a cooperative game where all players win or lose together.[1] The players share the common objective of discovering the circumstances of the ghost's death.[1]
**Setup**
1. The Ghost and the Psychics sit across from each other.[2]
2. The Ghost draws one Plot Card and places it on their card holder for Round #1.[2]
3. The Ghost draws two extra Plot Cards and places them face down to be used for Round #2 and Round #3.[2]
4. The Ghost takes the 3 Ticket Tokens.[2]
5. The Ghost shuffles all Vision Cards face down to form a draw pile and draws their first 7 Vision Cards.[2]
6. The Psychics unfold the board and place it in the middle of the table.[2]
7. The Game Turn Marker is placed next to space #1.[2]
8. Each player chooses a color and takes the matching Intuition Pawn and Innocent Token.[2]
9. The Witness token is placed next to the board.[2]
10. For Round #1, the Ghost shuffles all Character Cards, draws 9 at random, and places them face up at random on the different spaces of the board.[2]
11. Location Cards are kept within reach of all players.[2]
**Gameplay**
The game is played in successive turns, with players having a total of 6 turns to complete Round #1 and Round #2.[3]
**Round #1: Clear a Character**
1. Each Psychic must find the Character Card linked to their color on the Plot Card.[3]
2. The Ghost chooses a Psychic and looks at the Plot Card to check which Character Card is attributed to them.[4]
3. The Ghost creates a vision using one or several Vision Cards from their hand to help the Psychic find the correct card.[4]
4. The Ghost gives the chosen Vision Cards to the Psychic face up.[4]
5. The Ghost draws new Vision Cards until they have 7 in hand.[4]
6. The Ghost repeats this process for all Psychics for that turn.[4]
7. The Psychics look at the cards and may freely discuss them to deduce the correct Character Card.[4]
8. A Psychic places their Intuition Pawn on the card they believe is correct.[4]
9. When the Psychics are ready, they tell the Ghost their choice.[5]
10. The Ghost reveals if they are correct by comparing the chosen space with the matching space on the Plot Card.[6]
11. If a Psychic is correct, they recover their Intuition Pawn and place their Innocent Token on the empty space left by the character.[7]
12. If a Psychic is incorrect, a new turn begins in Round #1 and the Game Turn Marker moves forward one space.[6]
13. If all Psychics find their cards, the game moves to Round #2.[6]
**Round #2: Eliminate a Location**
1. The Ghost prepares a new setup by shuffling and placing 9 Location Cards on the board instead of Character Cards.[7]
2. The Ghost draws a new Plot Card for this round.[7]
3. The round plays exactly as Round #1, but Psychics try to eliminate a Location Card instead of clearing a Character.[7]
4. If all Psychics find their Location Card by the end of the sixth turn, the game proceeds to Round #3.[7]
5. If they do not succeed by the end of the sixth turn, the game is over and everyone loses.[7]
**Round #3: Reveal the Culprit and Crime Scene**
1. The Ghost shuffles the three remaining Character Cards from Round #1 and places them at random on the second line of the Board.[5]
2. The Ghost shuffles the three remaining Location Cards from Round #2 and places them at random on the third line of the Board.[5]
3. The Ghost discards their previous Plot Card and draws the last one, placing it in the card holder.[5]
4. The Ghost considers only the Roman numeral on this card to identify the set of cards the Psychics must find.[5]
5. The Ghost creates a final vision by choosing exactly two Vision Cards: one linked to the correct Character and one to the correct Location of the identified set.[5]
6. The Ghost shuffles these Vision Cards before handing them to the Psychics.[5]
7. The Psychics discuss the vision and must agree on a choice (or hold a vote to resolve a tie).[5]
8. The Psychics tell the Ghost their chosen set.[5]
9. If the Psychics chose the set matching the Roman numeral on the Plot Card, all players win.[5] Otherwise, all players lose

what this block IS: the PASSAGE SEARCH's own results — the same search that fills this page's closest-passages list — and NOT the passages the answerer read. Answering runs its OWN retrieval: a far wider candidate pool, re-ranked down to a final handful, plus floors this search never applies — the base rulebook, surviving errata corrections, and one slot per book on a multi-book read. Each of those armed only if THIS ask sent what it needs: the boost block names the ids it forwarded, and the scope line names the books it read. A document the answer CITES that no row here names is therefore EXPECTED, not a defect: two searches, two candidate pools, two orders. The answerer's own final rows are shown in their own block below, beside these and never mixed into them.

score = the fused retrieval score (reciprocal-rank fusion over the search arms) — NOT a cosine similarity. This ruling ran the THREE-ARM fuse (full-text + vector + the doc-priority boost arm, which carried the base rulebook and/or the errata corrections this query matched), whose arithmetic ceiling is 0.04918 — all three arms ranking the same chunk #1 (ceiling = arms/(k+1) at k=60). The measured healthy band 0.016–0.033 was measured on TWO-arm asks and does not bound this one: its high end is the two-arm ceiling, and a third arm has room above it. A chunk only one arm ranked highly lands near 0.016 (that one arm's #1 vote), so 0.03 here is an excellent hit, not a 3% match.

per-arm ranks (the rank each search arm gave a chunk): NOT DISCLOSED by the gateway. Fusion happens gateway-side and only the FUSED score crosses the wire, so rulesage cannot show them without a gateway change. The rank column below is the FUSED rank (position in the returned list), which is real.

token count per chunk: NOT DISCLOSED — chunk token counts are not reported on the ask path. The character counts below are of the bounded snippet/quote rulesage actually received — a real measurement of what we hold, never an estimate of the chunk.

what this block IS: the passages the ANSWERING read put in front of the answerer, in the order it read them — the other half of the two reads described above, and the one that decides what the answer could possibly say. Each row names the book it came from and where in that book it sits, what it scored when the search arms were fused, which arm carried it there, and whether the re-ranker chose it or a floor guaranteed it a slot. A row here that no passage-search row names is EXPECTED: a far wider pool, re-ranked, with floors the passage search never applies.

candidate pool: the answering read scored 12 passages, out of a ceiling of 80 set gateway-side. Both figures are reported by the gateway for THIS ask — measurements of what actually happened, not constants read out of anyone's source and printed here on faith.

floors armed for this ask: the base rulebook — armed · surviving errata corrections — not armed · one slot per book on a multi-book read — not armed. Every floor is stated on every ask, armed or not, so a floor that did not apply here is never mistaken for one this app does not know about.

arms fused for this ask: vector + full-text + the doc-priority boost arm. Stated separately from the rows because an arm that ran and carried nothing is a different fact from an arm that never ran.

watchdog
first-token watchdog: 30s per arming window (rulesage.table.first-token-watchdog-seconds), re-armed once by the passages frame — so the worst case before a reader falls back to polling is 60s. Whether it actually fired is a BROWSER-side decision that never reaches the server, so it is not recorded here. The stream path above is the server's half of that story: whether a delta was emitted at all.

this game registers NO errata cards (edition 1072), so "no registered errata card matched" above could never have matched one

Errata scope: the gate above matched this ruling's own edition only. When an ask also reads an expansion, that expansion's own registered errata cards stay outside the match — a stated phase-1 limitation, not a failed lookup.
