Game Architecture

Frontend Components

Each game consists of:

Game Container: Main component that initializes the game
Game UI: User interface elements specific to the game
Game Logic: Business logic implementing game rules
Game State: State management for the game session
Animation Controller: Manages game animations and effects

Backend Services

Games are supported by these backend services:

Game Session Service: Manages active game sessions
Random Number Generation Service: Provides auditable random values
Transaction Service: Handles bets and winnings
Statistics Service: Tracks game outcomes and player statistics

Game Integration

Adding a New Game

To add a new game to the platform:

Create a new feature module in the frontend
Implement the required game components
Add the game metadata to the game registry
Implement any required backend services
Add the game to the home screen carousel

Game Development Guidelines

Fairness and Security:
- All games use server-side randomization service
- Game odds are transparent and mathematically verified
- House edge is clearly documented
- All transactions are atomic and auditable
User Experience:
- Consistent UI patterns using shared Angular components
- TailwindCSS for consistent styling
- Responsive design for mobile and desktop
- Audio feedback and visual effects
- Clear game instructions and rules
Performance Standards:
- Games initialize in under 2 seconds
- Animations maintain 60fps on target devices
- Optimized bundle sizes
- Lazy loading for game modules
Technical Requirements:
- TypeScript strict mode compliance
- Comprehensive error handling
- Real-time balance updates
- Transaction rollback capabilities
- Cross-browser compatibility
Code Quality:
- ESLint and Prettier formatting
- Checkstyle compliance (backend)
- Unit test coverage requirements
- Code review mandatory
- Documentation standards

Transaction Flow

Betting Process

Player selects bet amount
Game validates against player balance
Bet amount is reserved (not yet committed)
Game executes and determines outcome
Transaction is finalized (win or loss)
Player balance is updated

Transaction Verification

All game transactions:

Are logged with unique identifiers
Include initial state, actions, and final state
Are cryptographically signed
Can be audited by administrators

Testing and Quality Assurance

Current Testing Coverage

Implemented tests for core game functionality:

Backend Testing

Balance Service Tests: Atomic transaction testing
Coinflip Service Tests: Randomization and payout validation
Dice Service Tests: Game logic and outcome verification
User Service Tests: Authentication and profile management

Frontend Testing

Component Unit Tests: Jasmine/Karma test suite
Service Integration Tests: API interaction testing

Fairness tests verifying expected return to player (RTP)
Security tests for exploit prevention

Quality Assurance Process

Before release, each game undergoes:

Automated test suite execution
Code review by development team
Mathematical verification of odds and payouts
Security audit for potential vulnerabilities
Cross-browser and device compatibility testing
Performance profiling and optimization
