Scribble assignment - Ankit

[ankit-everest]

Summary

Implemented the complete Scribble multiplayer game using an Express + TypeScript backend and React + Vite frontend. The application uses in-memory state management and HTTP polling for synchronization, following a Spec-Driven Development workflow across all four business scenarios.

Architecture

• Express + TypeScript backend with Zod validation
• React 18 + Vite frontend
• In-memory game state management
• HTTP polling (~2s) for synchronization
• No WebSockets, databases, authentication, or persistence

Room Setup & Lobby

• Creator becomes the host
• Room and player validation with clear error handling
• Automatic lobby polling
• Host-only game start with a minimum of 2 players
• Multi-room isolation

Game Start & Drawer Flow

• Deterministic drawer assignment
• Deterministic word selection
• Drawer-only word visibility
• Game start validation and role management

Gameplay Interaction

• Shared drawing canvas with clear functionality
• Guess submission and validation
• Case-insensitive word matching
• Guess history synchronization via polling
• Deterministic scoring (100 for correct, 0 for incorrect)

Result & Restart

• Correct word, final scores, and guess history visible to all players
• Host-controlled restart flow
• Players preserved across restarts
• Round state cleared and lobby restored

Validation

Validated all four business scenarios using multiple browser sessions, covering room management, gameplay flow, scoring, synchronization, room isolation, and restart behavior.
