System Requirements Document (SRD)

Project Name: green-multiplayer

1. Introduction

The green-multiplayer project aims to deliver a production-ready online multiplayer Ludo game app with voice chat and Facebook integration. This document outlines the system requirements for the initial phase of development, focusing on creating a simple yet functional multiplayer Ludo game with core features such as real-time gameplay, voice chat, and Facebook login. Monetization features will be deferred to a later phase.

Ayush Patel, based in India, envisions a vibrant and engaging gaming experience that combines timeless Ludo gameplay with modern social and communication features. This SRD will serve as the blueprint for the development team to ensure alignment with Ayush's vision.

2. System Overview

The green-multiplayer system will be a mobile application designed for Android and iOS platforms, developed using React Native for the frontend and Node.js with Express for the backend. The game will adhere to classic Ludo rules and provide real-time multiplayer functionality, voice chat, and seamless Facebook integration.

Key features include:

• Real-time gameplay for 2–4 players.
• Smooth animations for dice rolls and token movements.
• Voice chat for enhanced player interaction.
• Facebook login and friend invite functionality.

The system will prioritize user engagement and scalability, ensuring a robust foundation for future enhancements such as monetization and additional gameplay features.

• Goals: Ensure system stability, prevent cheating, and optimize revenue streams.

5. Visuals Colors and Theme

Color Palette

The green-multiplayer project will feature a vibrant and playful color palette to reflect the fun and social nature of the game.

• Background: #F9F9F9 (Soft white for a clean and welcoming look)
• Surface: #E8F5E9 (Light green for game boards and panels)
• Text: #1B5E20 (Deep green for readability and contrast)
• Accent: #FFEB3B (Bright yellow for dice and token highlights)
• Muted Tones: #BDBDBD (Gray for secondary elements like timers and borders)

6. Signature Design Concept

The Interactive Ludo Board Experience

The green-multiplayer homepage will feature a dynamic 3D Ludo board that comes to life as users interact with it.

• Visuals: The board will rotate slightly as users swipe across the screen, creating a tactile and immersive experience. Dice rolls will feature a glowing animation, and tokens will leave a trail of sparkles as they move.
• Animations: When players log in, their avatars will "pop" onto the board with a bounce effect, accompanied by a cheerful sound.
• Transitions: Game rooms will open like treasure chests, revealing the players inside with a burst of confetti.
• Micro-interactions: Hovering over buttons will create a ripple effect, and tapping them will trigger a subtle vibration for feedback.

This design will make the app instantly fascinating and memorable, ensuring users are captivated from the moment they open the app.

7. Non-Functional Requirements

• Performance: Ensure smooth gameplay with minimal latency for real-time interactions.
• Scalability: Support up to 10,000 concurrent players in the initial phase.
