Crossed Coordinates

How to play

1. 1

   Crossed Coordinates is a one-team game for 4–12 Navigators. A match has exactly four rounds; every round presents four public candidate places, with no personal score or individual winner.

2. 2

   Every active player receives one private fragment and four allowed features. With 4–7 players, one fragment quietly comes from another candidate map; with 8–12 players, two fragments come from two different candidates. Nobody, including their holders, sees a special role before the reveal.

3. 3

   Players have 20 seconds to study their fragment. They may confirm immediately, but even when everyone confirms, the shared stage cannot advance before 8 seconds. The fragment, its source, and everyone else’s available features are private: do not show the screen, read its wording aloud, or forward it outside the game.

4. 4

   During the 45-second encode stage, each Navigator selects exactly two different features from the four allowed by their fragment. There is no free text. An accepted signal locks once; a timeout or disconnect leaves no signal, and the app never fills one in.

5. 5

   After encoding, the server publishes only anonymous feature pairs in a shuffled order that stays fixed for the round. A signal identifier is unrelated to player identity, seat, or submission time; author mappings, individual ballots, and timestamps remain hidden even after the round.

6. 6

   The council lasts 120 seconds plus 5 seconds for each player beyond four, capped at 160 seconds. The host may advance after 60 seconds. Discuss which place explains the shared pattern and which one signal appears to have come from another map.

7. 7

   Players have 35 seconds to lock a private ballot containing exactly one place and exactly one anonymous distorted-signal choice—even when two fragments were distorted. A ballot locks once; skipping or timing out creates no vote.

8. 8

   Place consensus requires a unique leader with a strict majority, more than half of all active players; if that place is correct, score 200. Noise consensus requires a unique leader with at least max(2, ceil(N/3)) votes; if it matches either distorted signal, score 100. Ties and unmet thresholds score 0, with no hidden tie-break.

9. 9

   Alignment scores another 100 when at least ceil(3N/4) active players individually chose the target. A round is worth at most 400 and a match at most 1,600. The reveal lasts 18 seconds and the host may advance after 6; it shows the target, every anonymous original fragment and its source place, marks the distorted signals, and shows aggregate results and team score—but never authors or individual ballots.

10. 10

    Play in the same place or use an external audio or video call. play2gether.fun does not request camera, microphone, or location access and does not record audio or video. A participant reconnecting under the same identity receives only their own fragment and receipts for accepted actions. Anyone joining after the match starts observes until the next match; observers never receive private fragments or individual ballots.
