Per Rhys: card_game's solver is the real engine, so drop the redundant
adapter types in solitaire_data::solver rather than maintain a parallel
verdict/config/move vocabulary.
- Delete SolverResult, SolverConfig, SolverMove, and snapshot_to_solver_move.
The verdict now reads straight off card_game's return:
Ok(Some(instr)) = winnable (first move on the path)
Ok(None) = provably unwinnable
Err(_) = inconclusive (budget exceeded)
- SolveOutcome is now Result<Option<KlondikeInstruction>, SolveError>.
- try_solve / try_solve_from_state take plain (moves_budget, states_budget)
u64s; add DEFAULT_SOLVE_{MOVES,STATES}_BUDGET consts.
- snapshot_to_solver_move duplicated core's GameState::instruction_to_move,
so make that pub and have the hint convert the first-move instruction to
highlighted (from, to) piles through it. Re-export KlondikeInstruction
from solitaire_core.
- HintSolverConfig now holds { moves_budget, states_budget } instead of
wrapping the deleted SolverConfig.
- Update consumers: pending_hint, play_by_seed (verdict badge), game_plugin
(choose_winnable_seed), input_plugin, hud_plugin, and the gen_seeds /
gen_difficulty_seeds asset tools.
solver.rs drops 274 -> 140 lines. cargo test --workspace and
cargo clippy --workspace --all-targets -- -D warnings pass.

Ferrous Solitaire
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.

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.
