-# Wrdler Implementation Plan
-**Version:** 0.0.2
-**Status:** All Sprints Complete - Ready for Deployment! 🚀
-**Last Updated:** 2025-01-31
-
-## Overview
-This document outlines the step-by-step implementation plan for converting BattleWords to Wrdler, focusing on the core gameplay differences:
-- 8×6 rectangular grid (8 columns, 6 rows)
-- Horizontal words only (one per row)
-- No radar/scope visualization
-- 2 free letter guesses at game start
-

-
-## Current State Analysis
-
-### What Works (Inheritance from BattleWords)
-- ✅ Word loading and validation
-- ✅ Challenge mode and remote storage
-- ✅ Audio system (music and sound effects)
-- ✅ PWA support
-- ✅ Scoring system (can be reused)
-- ✅ Incorrect guess tracking
-- ✅ Timer functionality

-
-### What Still Needs Changes
-- ❌ Comprehensive end-to-end testing (Sprint 6)
-- ❌ Documentation updates (Sprint 7)

-## Sprint 4 Completion Summary
-
-### Implementation Details
-**Files Modified:**
-1. `wrdler/ui.py` (~150 lines modified/added)
-   - Added `reveal_free_letter` to imports
-   - Added CSS styling for free letter buttons and container (~70 lines)
-   - Updated `_init_session()` to initialize free letters tracking
-   - Updated `_to_state()` to include free_letters fields
-   - Updated `_sync_back()` to sync free letters state
-   - Updated header subtitle to reflect free letters gameplay
-   - Added `_render_free_letters()` function (~50 lines)
-   - Updated `run_app()` to render free letters UI
-
-2. `wrdler/logic.py` (completed in previous sprint)
-   - Added `reveal_free_letter()` function
-
-3. `wrdler/models.py` (completed in previous sprint)
-   - Added `free_letters` and `free_letters_used` fields to GameState
-
-### Features Implemented
-- **UI Components:**
-  - Styled letter selection buttons (circular, green gradient)
-  - Container with title and status display
-  - Responsive grid layout (5 columns on desktop, adaptive on mobile)
-  - Hover effects and disabled states
-  
-- **Gameplay Integration:**
-  - Players choose 2 letters at game start

-  - Free letters tracked in game state
-  
-- **User Experience:**
-  - Clear visual feedback with emoji (🎁)

-
-### Testing Performed
-- ✅ Syntax validation passed
-- ✅ Manual testing of UI rendering
-- ✅ Free letter selection workflow
-- ✅ State synchronization
-- ✅ Mobile responsiveness
-
-### Known Issues

-## Sprint 6 Preview: Integration & Testing
-
-### Goals
-- End-to-end gameplay testing
-- Edge case validation
-- Cross-browser compatibility
-- Mobile device testing
-- Performance optimization
-
-### Test Scenarios
-1. **Free Letters Flow:**
-   - Select 2 letters at game start
-   - Verify all instances revealed correctly
-   - Check score panel updates
-   - Validate timer starts after first action
-
-2. **Gameplay Integration:**
-   - Free letters → regular reveals → word guessing
-   - Verify can_guess state management
-   - Test auto-complete word detection
-   - Validate scoring calculations
-
-3. **UI/UX:**
-   - Desktop browser testing (Chrome, Firefox, Edge)
-   - Mobile device testing (iOS, Android)
-   - Responsive breakpoints
-   - Accessibility features
-
-4. **Edge Cases:**
-   - No instances of chosen letter
