I am requesting a complete software design and documentation package to support the future development of a game engin.
Important:
No development or coding is required at this stage — only detailed, production-grade documentation that explains every aspect clearly, allowing a development team to build the system later without ambiguity or rework.
System Overview
The system must manage and deliver preconfigured games to clients, with flexibility to support both current and future game types.
The system should initially support, but not be limited to, the following game types:
Quiz Games
Shake and Win
Spin and Win
Memory Card (Hide & Seek)
The architecture must ensure:
Future games can be added without requiring database redesign or API changes.
Scalability to handle thousands of concurrent users.
Modular and maintainable codebase from day one.
Required Deliverables (Documentation Only)
Each of the following sections must be covered comprehensively:
1. Software Architecture Document
High-level system design: Frontend, Backend, APIs, Database, and Third-party Integrations.
Overall system architecture (e.g., layered, modular monolith, or microservices — with justifications).
Component interaction diagrams (backend services, authentication, notification systems, etc.).
Scalability, modularity, and maintainability considerations for future expansion.
Security design overview (authentication, authorization, API security, data protection).
2. API Design Documentation
Complete API specifications for all required operations (game management, player participation, prize claiming, etc.).
Authentication mechanism (API Key, OAuth2, or JWT — including full flow diagrams).
Detailed API request and response structures (including example JSON for success and error cases).
Standardized API error response formats (with error codes, messages, and scenarios).
Rate limiting standards and strategies to prevent abuse.
3. Database Design
Logical Entity-Relationship Diagram (ERD) representing all major entities and their relationships.
Physical database table definitions with fields, types, primary/foreign keys, indexes, constraints, and normalization standards.
A generalized table structure that can accommodate any new game type without schema modification.
Guidelines for database scalability (partitioning, sharding considerations if necessary).
4. Data Flow Diagrams, Process Flowcharts, and System Sequence Diagrams
Data flow diagrams for each major game journey:
Shake Your Device
Guess the Correct Answer
Predict the Winner
Memory Card (Hide & Seek)
System sequence diagrams to illustrate key user journeys (e.g., game play, prize claiming, whitelisting verification).
Internal service interaction and data flow mapping.
5. Developer Blueprint Instructions
Proposed backend folder and project structure (including layers such as Controllers, Services, Repositories, DTOs, etc.).
Clear class/module placement guidelines.
Coding standards and best practices (naming conventions, error handling practices, transactional boundaries, etc.).
Environment setup instructions and tech stack recommendations.
Additional Core Features Documentation
6. Prize Allocation Mechanism
Mechanisms for direct prize allocation and draw-based prize distribution.
Prize eligibility validation logic.
Manual vs. automated prize fulfillment processes and flows.
7. Customer Whitelisting System
Customer eligibility and whitelisting based on Campaign ID.
Enforcement of single active participation per user per campaign or game.
API to validate whitelisting in real-time before gameplay.
8. Game Configuration System
Step-by-step wizard design for setting up a game campaign (Game → Prize → Prize Distribution → Whitelisting → Terms & Conditions).
Draft saving functionality.
Ability to clone existing game configurations for quicker setup.
9. Notifications System
Notification system design supporting:
Push Notifications
In-App Popups
SMS triggers
Template-based notification system (dynamic placeholders, localization support).
Notification event lifecycle (created, scheduled, triggered, delivered).
10. Reporting Engine
Real-time and historical reporting structures.
Reporting formats for business and customer service teams.
Export options including CSV and PDF.
Summarization dashboards with KPIs (e.g., participation rates, prize claim rates, game success rates).
Final Notes
The entire documentation should be clear, detailed, structured, and at a production-grade quality level, suitable for direct handover to a software development team.
All diagrams should be included (architectural, flowcharts, ERD, sequence diagrams, data flow diagrams).
The document should eliminate guesswork, clearly specifying what needs to be built, how it should be built, and why it should be built in that way.
Flexibility and future extensibility should be fundamental principles across all layers of design.
