Now that foundations are unlocked and "completing" one is a real moment (rather than a foregone conclusion based on suit assignment), each Ace-through-King run gets its own small celebration when the King lands. Three layers fire on a single FoundationCompletedEvent emitted by game_plugin's handle_move when a successful move leaves a PileType::Foundation pile holding 13 cards: 1. King card scale-pulse via a new FoundationFlourish component. Triangular curve 1.0 → 1.15 → 1.0 over MOTION_FOUNDATION_FLOURISH _SECS (0.4s) — same shape as the existing ScorePulse so the feel matches. 2. Pile-marker tint flourish via FoundationMarkerFlourish — the foundation marker's sprite colour lerps to STATE_SUCCESS for the first half of the duration then fades back. Reuses the existing success-signal palette; no new colour token. 3. Audio cue: foundation_complete.wav, a synthesised C6→E6→G6 triad with 2nd-harmonic warmth and AR decay (~240 ms). Sits an octave above win_fanfare's root so the layered fourth-completion + win cascade reads cleanly. Generated via solitaire_assetgen's foundation_complete() function and embedded via include_bytes!(). The visual systems run .after(GameMutation) so the post-move pile state is visible when the King is identified. Both flourish components remove themselves once elapsed time exceeds duration — no animation queue or scheduler integration needed. Pure foundation_flourish_scale(elapsed, duration) helper is unit-tested for the curve, edge clamps, and zero-duration safety. Three integration tests on the firing logic verify the event fires exactly once when a King completes a foundation, doesn't fire for non-foundation moves, and doesn't fire when the foundation is at 12 cards. The fourth completion still co-occurs with the win cascade — the two layer cleanly because the flourish's scale is on the King card sprite while the cascade is a screen-shake + per-card rotation, and the foundation_complete ping is a higher octave than the win fanfare's root.

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
- 18 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.

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
