How do you score the game?

Asked with: Underwater Citiesbg-247763-en-1e

Points are scored throughout the course of the game through certain cards or during Production.[1] Scoring also occurs at the end of the game for various aspects of an underwater network.[2]

The following scoring methods are available:

* **During Gameplay:**

* Players can score 1 point for each space they were supposed to advance if their marker ends up on space 1 of the Federation track after advancing past it.[3]

* Certain blue metropolis tiles may provide 2 points during each Production phase if connected.[4]

* **At the End of the Game:**

* **Metropolises:** Score 3 points for each metropolis connected to your network, including starting brown and blue metropolises and any gained during play.[4] A specific metropolis in the upper left corner of a player board provides points if connected with both tunnels.[5]

* **Tunnels:** Score 5 points for eight tunnels, 7 points for nine, or 9 points for ten or more (upgraded tunnels count).[4]

* **Cities:** Score 4 points for five connected cities, 8 points for six, or 12 points for seven or more.[4]

* **Buildings next to Cities:** Points are based on the number of different buildings next to each connected city: 2 points for a city with no buildings, 3 points for 1 type of building, 4 points for 2 types, and 6 points for all 3 types.[5]

* **Special Cards:** Score 2 points for each Special card played and paid for (including those with instant effects, but excluding discarded Special action cards).[4]

* **Upgraded Structures:** Score 4 points for each set of 4 different upgraded structures (counting only connected buildings and tunnels adjacent to a city).[4] This is calculated by finding the lowest number among connected upgraded farms, laboratories, desalination plants, or upgraded tunnels adjacent to a city, and multiplying that number by four.[4]

* **Specific Cards:** Points may be scored for specific cards claimed,[1] trade surplus cards marked with a specific symbol,[5] or accomplishments rewarded by certain cards.[5]

* **Resources:**

* Sell all biomatter for 2 credits each.[5]

* Buy 1 point for every 4 credits, kelp, science, or steelplast spent in any combination; leftover resources do not count.[5]

The specific order of final scoring is depicted on the player's final scoring card.[1] In a solo game, the player wins if they finish with at least 7 connected cities and at least 100 points.[6]

retrieval — what the passage search returned

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. How much wider that pool was is set gateway-side and is NOT REPORTED for this ruling, and neither are the answerer's final rows — so rulesage has nothing of its own to show beside these.

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 the answerer read — the passages it actually had in front of it

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.

the passages the answerer read: NOT RECORDED for this ruling. Any of three things leaves this empty, and they are all different from the answerer having had nothing to read: this ask may never have reached a gateway at all; a multi-book ask keeps each book's own context on that book's own page rather than here; or the gateway build that answered may simply not report it. What this NEVER means is that the answerer read nothing — an answer was composed from passages either way, and their absence here is a gap in what we were told, not in what it read.

generation — timing and the path taken

timing split: retrieval 339 ms · first delta 10478 ms · total 14787 ms (retrieval and first-delta both measured from the START of gateway work, so first-delta INCLUDES retrieval — do not subtract)
full breakdown: queued 0 ms · retrieval 339 ms · ask 14427 ms · gateway work 14787 ms · total 14787 ms

live seat (read from the running child): answering — gemma4:26b think:false · num_ctx 32768 (live-verified 48s ago)
stream path: streamed — the gateway pushed at least one accumulated draft
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.
num_ctx · think posture: both are the CHILD's settings, not rulesage's, and no ask reply carries them — an answer never states which context window or think posture produced it. The live-seat line above reads them from the running child instead, where the gateway can answer for itself; it describes the child NOW, not this ask.

disposition

outcome: ANSWERED — Answered
abstain rationale (n/a — this ruling answered): answered — no abstain rationale applies

setup-shape — why the checklist band did or didn't render

decision: NOT_SETUP_SHAPED — no setup-shape pattern matched this question

errata registry — what the gate above had to match against

this game registers NO errata cards (edition 193), 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.
