System Requirements Document (SRD)

Project Name: earthy-cricket

1. Introduction

The earthy-cricket project is an ambitious, full-scale, production-level cricket card game application envisioned by Sujal Kabra. This game combines real-life cricketer data with advanced card mechanics and competitive gameplay systems. Designed for scalability and professional-level quality, the project aims to deliver a hybrid experience of realism, strategy, and controlled randomness, akin to popular games like FIFA Ultimate Team and Clash Royale.

The primary goal is to create a dynamic, engaging, and modular platform that can grow into a full-fledged product, incorporating real-time data, multiplayer capabilities, and optional monetization features.

This document outlines the system requirements, architecture, and design principles for the earthy-cricket project.

2. System Overview

The earthy-cricket application is a competitive cricket card battle game where players collect, upgrade, and compete using real-life cricketers represented as cards. The system integrates real-time player statistics, dynamic card ratings, and advanced gameplay mechanics to ensure a realistic yet fun experience.

Key features include:

• Real cricketer data integration via APIs or datasets.
• Advanced card mechanics with rarity levels, special abilities, and leveling systems.
• Turn-based gameplay with AI-driven match simulations.
• Multiplayer modes, leagues, and leaderboards.
• Modular architecture for scalability and future feature additions.

The system will be built using a modern tech stack, including React.js for the frontend, Node.js or Django for the backend, and MongoDB or PostgreSQL for the database.

6. Signature Design Concept

"Cricket Stadium in Your Hands"

The homepage will feature an interactive 3D cricket stadium that comes alive as users navigate.

• Animation: The stadium lights up with spotlights as the user hovers over different sections (e.g., "Play Match," "Open Packs," "Leaderboard").
• Dynamic Elements:
  • Player cards appear as holograms on the field, flipping and glowing when selected.
  • A scoreboard updates in real-time with user stats and achievements.
• Micro-interactions:
  • Clicking on a card triggers a zoom-in animation with detailed stats and abilities.
  • Opening a card pack creates a cinematic experience with confetti and sound effects.
• Color Shifts: The background transitions from day to night based on the user's local time, adding a sense of immersion.

This design ensures the first impression is both memorable and engaging, setting the tone for a premium gaming experience.

7. Non-Functional Requirements

• Performance: The system should handle up to 10,000 concurrent users with minimal latency.
• Scalability: Modular architecture to support future features like new game modes and monetization.
• Security: Implement JWT authentication and anti-cheat mechanisms.
• Localization: Support for multiple languages, starting with English and Hindi.
• Availability: 99.9% uptime with robust error handling and recovery mechanisms.

8. Tech Stack
