First vertical slice: the whole shell plus two games playable end to end,
so every layer is exercised before the other nine games are built on it.
Games
- Euchre: bowers, ordering up, dealer discard, going alone, stick the
dealer, and full scoring. Rule variants (deck size, points to win,
stick the dealer, going alone) are toggles in game setup.
- Sequence: two-eyed and one-eyed jacks, free corners, locked sequences,
the shared-chip limit, and dead-card exchange. Teams, players per team
and the sequence target are toggles.
- The board layout in SequenceBoard is generated, not the commercial
board — it holds every structural property the rules need, but does not
match a physical board. Documented in docs/RULES-sequence.md.
Multiplayer
- One transport abstraction over newline-delimited JSON, implemented
twice: LAN via NSD discovery and TCP, Bluetooth via Classic RFCOMM.
A lobby advertises on both at once, so a table can mix them.
- Host-authoritative: clients send move intents, the host re-validates
every one against the rules, and each client receives a state redacted
for its own seat so hidden information never crosses the wire.
- Seats start as AI and are handed to people as they join, which is what
makes any mix of humans and AI work without a separate code path.
Shell
- Main menu lists all eleven games; the nine without engines are marked
coming soon and are driven entirely by GameCatalog.
- Settings: sound, animation speed (one multiplier drives card movement
and AI thinking time), and OTA updates from the latest GitHub release.
- Layouts measure available space rather than assuming an orientation.
The game package is free of Android types, so the rules engines and AI
run under plain JUnit; 43 tests cover ranking, following suit, scoring,
sequence detection, redaction, wire round-trips and full random and AI
playthroughs.
