Two more games on the existing framework — no changes were needed to the lobby, networking, settings or update layers, which is what the shared GameRules/GameAi contract was for. President - Threes low, twos high. Lead any number of one rank; follow with the same count of a higher rank, or pass. When everyone has passed the pile comes down and the last player to play leads again. - Toggles: player count, rounds, twos clear the pile, four of a kind bombs, and the between-round card exchange. - Plays are offered as whole sets rather than by selecting cards. A set is the unit of the game, so choosing from the legal sets is both easier to operate and impossible to get wrong. Golf - 4, 6 or 9 card grids. Draw from stock or discard, then either swap the card in or — only if it came off the stock — throw it and turn one of your own over. A card taken from the discard pile has to be used. - Matching columns cancel to nothing; on the 3x3 board rows do too, but not on the shallower grids where three cards are not a line. - Face-down cards are hidden from everyone including their owner, which is the point of the game: viewFor masks them with a fixed placeholder so the real card never reaches the device that has not turned it over. Both engines are pure Kotlin and unit tested — 71 tests now, covering ranking, legal moves, pile and hole resolution, scoring, redaction, wire round-trips, and full random and AI playthroughs. The Golf test also checks the AI actually beats random play rather than merely being legal. Also widened the setup screen's option chips to wrap: the reveal-count row carries up to ten, and a chip off the edge of the screen is a setting that cannot be changed — the same failure as the Euchre Pass button.

Pro Libertate Games
A collection of card and board games for Android, playable against the computer or against other people over Wi-Fi (LAN) or Bluetooth.
What works today
The app shell is complete and two games are playable end to end:
| Playable | Euchre, Sequence, President, Golf |
| Listed, not yet implemented | Kaiser, Wizard, Crazy 8s, Mastermind, Backgammon, Chess, Checkers |
Unimplemented games appear in the menu marked Coming soon on dev builds
only — a production release lists just the games that can actually be played,
so nobody installs it and taps into a dead end. The menu decides this from the
installed APK's own version name, so it follows the build rather than the
channel selected for future updates. Adding one means
writing a GameRules implementation, a GameAi, and a screen, then flipping
available in GameCatalog — the menu, lobby, networking, settings and OTA
layers are game-agnostic and need no changes.
Playing with other people
Pick a game, choose Host a game for others to join, and the device advertises itself on every radio it has. Other devices choose Join a game nearby and pick the host from the list. Seats start out filled by the computer and are handed to people as they join, so any mix of humans and AI works — whatever is still marked Computer when the host starts stays AI.
- Wi-Fi (LAN) — both devices must be on the same network. Discovery uses mDNS/NSD; play runs over a TCP socket.
- Bluetooth — devices must already be paired in Android's Bluetooth settings. Play runs over Classic RFCOMM. Scanning for unpaired devices is not implemented.
Both transports can be live at once, so some players can be on Wi-Fi and others on Bluetooth at the same table.
How a match is kept in step
The host is authoritative. Clients send intents ("I would like to play this card") and the host re-validates every one against the rules before it takes effect — a client cannot make an illegal move by sending a malformed message. Each client is then sent a state redacted for its own seat, so opponents' hands and the deck order are never transmitted to devices that should not see them.
Settings
- Sound on/off.
- Animation speed, 0.5×–2×. One multiplier drives card movement and how long the computer appears to think.
- Updates — check on launch, or check on demand, from either of two
channels:
- Production — stable builds, published from
main. - Dev — preview builds, published from
devon every green CI run.
- Production — stable builds, published from
Branding
The launcher icon is a single square of the Wallace tartan, and the app opens on a tartan splash carrying the name in a Celtic uncial hand for two seconds before fading into the menu.
The tartan is drawn, not an image: ui/theme/Tartan.kt lays the sett down as
warp and then as weft at half opacity, which is what produces the blended
squares instead of a flat grid. The icon is the same construction as a vector
drawable, so it stays sharp at every density and needs no PNGs.
Two honest caveats:
- The sett is an approximation.
WallaceSettreproduces what the Wallace tartan reads as — a bold red and black check divided by a narrow gold overstripe — but the registered threadcount could not be verified, so the numbers were chosen to look right rather than to be authoritative. They are plain data; replacing them with the registered counts rebrands the whole app and needs no other change. - The typeface is bundled under a licence. Uncial Antiqua, © 2011 Brian J. Bonislawsky DBA Astigmatic, Reserved Font Name "Uncial Antiqua", used under the SIL Open Font License 1.1. The full licence is at docs/licenses/UncialAntiqua-OFL.txt and must stay with the font — the OFL requires it to be distributed alongside.
Screen sizes
There are no fixed orientations or hard-coded card sizes. Layouts measure the space they are given: the menu grid reflows by width, the Sequence board is always square and sized to fit whatever is left after the hand, and card widths are a fraction of the smaller screen dimension. Rotation is handled inside the activity, so a hand is not lost when the device turns.
Building
./gradlew assembleDebug # APK at app/build/outputs/apk/debug/
./gradlew testDebugUnitTest # rules engines and AI
Requires JDK 17 and the Android SDK (compileSdk 34).
CI
.github/workflows/ci.yml— builds, tests and lints ondevand on pull requests intodevormain. Its APK artifact is a dev build, versioned1.0.0-dev..github/workflows/release.yml— on push tomain, builds the APK and publishes it as a GitHub Release taggedv1.0.<run-number>. The in-app updater reads that tag, which is why the APK'sversionCodeis the same run number.
Update channels
Both pipelines publish, to two separate channels:
| Channel | Published by | Tag | Marked |
|---|---|---|---|
| Production | release.yml, push to main |
v1.0.<n> |
release |
| Dev | ci.yml, push to dev |
v1.0.<n>-dev |
prerelease |
Dev builds are published as prereleases deliberately: GitHub's "latest release" endpoint skips prereleases, so a production-channel install can never be handed a dev build even by accident. Pull requests build and check but never publish, so a PR from a fork cannot ship anything.
release.yml additionally refuses to run off any branch but main, so a manual
dispatch aimed elsewhere does nothing rather than shipping unreviewed code.
The two channels have independent version sequences — a build's versionCode
is the run number of the workflow that produced it, and the two workflows count
separately. Versions are therefore only ever compared within a channel; the app
reads the -dev suffix in its own versionName to know which channel it is on,
and treats a change of channel as an explicit switch rather than an upgrade.
One consequence: switching channels can be a downgrade as far as Android is
concerned, in which case the install is refused until the current copy is
uninstalled. The settings screen says so when it applies.
The debug keystore is committed on purpose: every build is signed with the same key, so an OTA update installs over the previous one instead of being rejected for a signature mismatch.
Rules
The exact rules implemented, and the options that vary them, are documented per game:
Layout
game/ rules engines and AI — pure Kotlin, no Android, unit-tested
cards/ deck, suits, ranks
engine/ GameRules / GameAi contracts, seats, table config
euchre/ Euchre model, rules, AI
sequence/ Sequence model, board, rules, AI
president/ President model, rules, AI
golf/ Golf model, scoring, rules, AI
net/ wire protocol, LAN and Bluetooth transports, lobby, match driver
settings/ DataStore-backed preferences
update/ GitHub Releases OTA updater
ui/ Compose screens
Keeping game/ free of Android types is deliberate: the same code drives the
AI, the host's authoritative state and the JVM unit tests.
