Adds a gear button + modal on /, /master with a native color picker and 8 preset swatches for the empty-cell background. The selected color repaints both the player card AND the master tracking grid via the --empty-cell-bg CSS variable. Default brown matches the physical Minh Tân paper card. settings-store.svelte.js: Svelte 5 rune-based reactive store, state hydrated on layout mount, persisted to localStorage key loto_settings. Validates hex (#rrggbb regex) before applying — keeps the CSS sink safe and ignores corrupt or shorthand-3-digit payloads. SettingsButton.svelte: gear icon, modal with picker + presets + reset + close, escape-to-close via window keydown listener (the trigger button retains focus on open, so a dialog-scoped handler would miss). eslint.config.mjs: declares Svelte 5 rune globals so .svelte.js stores lint clean. Docs synced: PDR, codebase-summary, system-architecture, roadmap.

# Development Roadmap
|
||
|
||
This document tracks **future work only**. Completed features live in git commit history, not here.
|
||
|
||
## Currently Implemented Features
|
||
|
||
The app is fully functional for core gameplay (Lô tô hội chợ Tân Tân variant):
|
||
- 9×9 player card with **exactly 5 per row and 5 per column**, columns
|
||
ascending top-to-bottom
|
||
- Cell marking (toggle crossed state); player can keep playing after Kinh
|
||
- Bingo detection and "Kinh!" celebration popup
|
||
- "Chờ X" waiting notifications
|
||
- Host number drawing from 1–90 deck
|
||
- 11×9 last-digit-aligned master board with draw-order overlay for fast
|
||
Kinh verification
|
||
- Player card rendered as 3 stacked Tân Tân mini-cards
|
||
(Minh Tân / Loại đặc biệt / Tấn tài tấn lộc) with cross-hatch dividers
|
||
- Settings modal: empty-cell color picker (color picker + 8 presets +
|
||
reset), applies to player + master grids, persisted to `loto_settings`
|
||
- Host's own player card (isolated instance)
|
||
- localStorage persistence
|
||
- Dark mode
|
||
- Mobile responsive
|
||
- Offline capable
|
||
- Unit tests (Vitest: 26 game-logic tests + 12 settings-store tests, 38 total passing)
|
||
covering constraint validation, persistence, and error handling
|
||
|
||
## Idea Phase
|
||
|
||
### Sound Effects on Bingo
|
||
Play celebratory chime or "Kinh!" voice snippet when row completes. Could use Web Audio API or `<audio>` tag. **Status**: Idea (no demand yet)
|
||
|
||
### Undo Last Cell
|
||
Allow player to undo the most recent cross/uncross action. Requires change history or state snapshot. **Status**: Idea (low priority)
|
||
|
||
### Theme Switcher
|
||
Explicit light/dark toggle button instead of relying on OS preference. **Status**: Idea (Tailwind already supports OS toggle)
|
||
|
||
### PWA Install
|
||
Add service worker and manifest for "Install App" prompt on Android/iOS. **Status**: Idea (would require server-side components)
|
||
|
||
## Considered Phase
|
||
|
||
### Multiplayer Sync (Real-time)
|
||
Host and players connect via WebSocket to sync called numbers and state. Requires backend server. Would enable:
|
||
- Decoupled devices (players' phones, host's laptop on big screen)
|
||
- Remote tournaments
|
||
- Master board auto-updates all players in real-time
|
||
|
||
**Consideration**: Out of scope for static export. Requires major refactor (SvelteKit API routes + WebSocket server). Deferred indefinitely.
|
||
|
||
### i18n Beyond Vietnamese
|
||
Internationalization (English, Chinese, etc.). Requires extraction of all Vietnamese strings and i18n library (next-intl). **Status**: Considered (low demand for non-Vietnamese users)
|
||
|
||
### Undo/Redo System
|
||
Full undo/redo stack with history navigation. Adds complexity to state management. **Status**: Considered (YAGNI for now)
|
||
|
||
## Testing
|
||
|
||
### Component Tests (Planned)
|
||
- PlayerBoard with mocked localStorage, $state/$derived verification
|
||
- Master page with different game states
|
||
|
||
### E2E Tests
|
||
- Player flow: generate card → click cells → verify bingo popup
|
||
- Host flow: new game → draw numbers → verify board state
|
||
|
||
**Tech**: Playwright
|
||
|
||
## Future Enhancements (Speculative)
|
||
|
||
### Export/Import Card
|
||
Allow player to export their grid as image or JSON, import someone else's card. Use Canvas API or print-friendly CSS.
|
||
|
||
### Leaderboard / Stats
|
||
Track games won, time per bingo, etc. Requires server-side persistence. Out of scope for static export.
|
||
|
||
### Accessibility Improvements
|
||
- ARIA labels for grid cells
|
||
- Keyboard navigation (arrow keys to move, Enter to toggle)
|
||
- Screen reader support
|
||
|
||
### Custom Number Range
|
||
Host selects range (e.g., 1–75 for American bingo) instead of hardcoded 1–90. Requires config UI and refactor of game logic constants. **Out of scope** per Lô tô hội chợ Tân Tân focus.
|
||
|
||
### Different Grid Sizes
|
||
Support 8×8 or 10×10 grids, or 3×9 European Bingo 90 tickets. **Out of scope** — variant locked to 9×9 Tân Tân format.
|
||
|
||
### Two-line / Full-house Win Tiers
|
||
European Bingo 90 patterns. **Out of scope** — Tân Tân uses single-line "Kinh!" only.
|
||

|
||
|
||
## Decision Rationale
|
||
|
||
All decisions follow **YAGNI** (You Aren't Gonna Need It), **KISS** (Keep It Simple), **DRY** (Don't Repeat Yourself):
|
||
- No multiplayer sync → adds server dependency, breaks static export (Cloudflare Pages)
|
||
- No i18n → Vietnamese-only community, localizing adds complexity
|
||
- Unit tests implemented → critical paths (constraints, persistence, settings) now have automated coverage
|
||
- Component/E2E tests deferred → small codebase, manual testing sufficient for UI flows
|
||
- No undo/redo → simple game, mistakes are play experience
|
||
- Svelte 5 runes → cleaner reactivity than hooks, smaller mental model
|
||
|
||
Future work gates on **real user demand**, not speculation.
