Adopts the four-file rule set the player added to the working tree:
- CLAUDE.md grows from a 114-line pointer doc to the 571-line
`unified-3.0` rulebook: hard global constraints (§2), engine
rules (§3), asset rules (§4), code standards (§5), build +
verification (§6), git workflow (§7), the change-control
ASK BEFORE list (§8), and the Context Injection System (§14).
- CLAUDE_SPEC.md — formal architecture spec: crate dependency
graph with forbidden_deps, data ownership map, state-machine
invariants ("52 cards always exist", "no duplicate IDs",
"all cards belong to exactly one pile"), sync merge contract,
server contract, validation checklist.
- CLAUDE_WORKFLOW.md — two-agent Builder/Guardian pipeline with
hard-fail patterns that auto-reject (core uses IO/Bevy/network,
GameState mutated outside GameLogicSystem, blocking async on
main thread, duplicate logic, merge altered incorrectly).
- CLAUDE_PROMPT_PACK.md — task-type templates.
Three duplicate rule passages removed:
- CLAUDE_SPEC.md §0 dropped no_panics_in_core / core_is_pure /
event_driven_engine — already canonical in CLAUDE.md §2.1, §2.3,
§3.1. Kept single_source_of_truth and sync_is_additive (those
describe data flow, not in CLAUDE.md).
- CLAUDE_SPEC.md §11 Prohibited Patterns now references CLAUDE.md
§11 instead of restating the same five forbidden items.
- ARCHITECTURE.md Design Principles dropped the pure-core /
no-panics / UI-first bullets — those are enforcement constraints
living in CLAUDE.md §2.1, §2.3, §3.3; this file describes the
design that motivates them. Kept the offline-first, one-language,
and plugin-based-Bevy bullets (those are descriptive, not
enforcement).

Solitaire Quest
A cross-platform Klondike Solitaire game written in Rust, with a card-theme system, full progression (XP / levels / achievements / daily challenges), and optional self-hosted sync so your stats follow you across machines.
Features
- Klondike Solitaire — Draw One and Draw Three modes; foundations are unlocked (any Ace lands in any empty slot, the slot then claims that suit)
- Card themes — bundled hayeah/playing-cards-assets default plus user-installable themes (drop a directory under the data dir or import a zip from Settings → Cosmetic)
- Modern HUD — reserved top band keeps cards from crowding the score readout; the action bar auto-fades when the cursor leaves it so it can't compete with the play surface
- Drag feel — every legal drop target is highlighted in green during drag; cards cast a soft drop shadow that lifts when picked up; the stock pile shows a remaining-count chip so you can see how close you are to a recycle
- Keyboard navigation — Tab cycles focus through buttons, arrow keys move within picker rows, Enter activates; works across every modal and the HUD action bar
- Progression — XP, levels, unlockable card backs and backgrounds
- 19 Achievements — including secret ones
- Daily Challenge — server-seeded so every player worldwide gets the same deal
- Leaderboard — opt-in, powered by your own self-hosted server
- Special Modes (unlocked at level 5): Zen, Time Attack, Challenge
- Sync — pull/push stats across devices via a self-hosted server
- Color-blind mode — blue tint on red-suit cards alongside the suit glyph
Building
Prerequisites
- Rust stable toolchain (
rustup install stable) - Linux:
libasound2-dev libudev-dev libxkbcommon-dev - macOS: Xcode Command Line Tools
# Fast development build
cargo run -p solitaire_app --features bevy/dynamic_linking
# Release build
cargo build -p solitaire_app --release
./target/release/solitaire_app
Controls
Every action also has a visible UI button — keyboard shortcuts are optional accelerators.
| Key | Action |
|---|---|
| Left click / drag | Move cards |
| Double click | Auto-move card to its best legal destination |
| Right click | Highlight legal moves for a card |
| Space / D | Draw from stock |
| U | Undo |
| H | Hint (highlight a legal move) |
| N | New game |
| Z | Zen mode |
| G | Forfeit (during pause) |
| Tab / Shift+Tab | Cycle keyboard focus |
| Enter | Activate focused button / auto-complete (when badge is lit) |
| Esc | Pause / dismiss modal |
| F1 | Help / controls |
| F11 | Toggle fullscreen |
| S / A / P / O / L / M | Stats / Achievements / Profile / Settings / Leaderboard / Menu |
Card themes
The default theme ships embedded in the binary, so the game runs
self-contained with no external assets. To install another theme, drop a
directory containing a theme.ron manifest plus 53 SVG files (52 faces +
1 back) under the platform data dir's themes/ folder, or import a zip
from Settings → Cosmetic. The picker chip lights up the moment a new
theme is registered. Themes are SVG-based, so they rasterise cleanly at
whatever resolution the window happens to be.
Sync Server (optional)
To sync stats across machines, run the self-hosted server. See README_SERVER.md for setup instructions.
Once the server is running, open Settings → Sync Backend, enter the server URL and your username, and register an account from within the game.
Running Tests
# All tests (982 passing as of v0.11.0)

# Lint
cargo clippy --workspace --all-targets -- -D warnings
Credits
Built on Bevy and the wider Rust ecosystem
(Tokio, Axum, sqlx, Serde, kira, and many more). Card faces come from
hayeah/playing-cards-assets
(MIT, derived from the public-domain vector-playing-cards library); the
default card back is original work; the UI font is FiraMono-Medium (OFL).
All audio is synthesized programmatically by this project. See
CREDITS.md for the full list and license details.
