Group Casino Week 5: Your Strategic 6-Day Plan for Collaborative Game Development (Python)
Here’s the thing about the Group Casino project - this isn’t just another coding assignment. It’s your crash course in professional software development: object-oriented design, team collaboration, code integration, and building something that’s genuinely fun to use. But here’s the challenge: you’ve got six days to go from individual programmers to a coordinated team delivering a working casino with multiple games.
That’s exactly why you need this study guide. I’m going to walk you through a day-by-day plan that’ll help your team not just complete the project, but build something you’re genuinely proud of. We’re talking about systematic planning, smart role division, and integration strategies that actually work.
Project Overview: Understanding the Challenge
The Group Casino Week 5 project requires your team to build a console-based casino simulation with these key requirements:
Technical Requirements
- 6+ Game Implementations: At least 3 gambling games, 1 non-gambling game
- Multi-Player Support: Games should handle multiple players
- Account Management: All players must reference a CasinoAccount
- Persistent Balances: Player balances persist across game sessions
- 80% Test Coverage: Comprehensive pytest testing required
- Console Interface: User-friendly command-line interaction
Architectural Constraints
- Object-Oriented Design: Emphasis on inheritance, polymorphism, encapsulation
- Memory Management: Proper object lifecycle management
- Modular Structure: Each game should be independently testable and maintainable
- Package Management: Use pip/requirements.txt for dependencies
Starting Point
The repository provides two example implementations:
- SlotsGame/SlotsPlayer: Basic gambling game template
- NumberGuessGame/NumberGuessPlayer: Non-gambling game example
The 6-Day Strategic Plan
Day 1: Foundation and Team Coordination (Planning Day)
Morning Session (2-3 hours): Project Analysis and Role Assignment
1## Team Meeting Agenda (90 minutes)
2
3### 1. Repository Exploration (30 minutes)
4- Everyone forks and clones the repository
5- Run existing tests: `pytest`
6- Explore provided SlotsGame and NumberGuessGame implementations
7- Review project structure and documentation
8
9### 2. Architecture Deep Dive (30 minutes)
10- Analyze CasinoAccount class structure
11- Understand Game and Player base classes/protocols
12- Map out how games integrate with the casino system
13- Identify common patterns in existing implementations
14
15### 3. Role Assignment and Game Selection (30 minutes)
16- Assign 1-2 people as "Casino Core Team" (main casino class, integration)
17- Remaining team members each choose a specific game to implement
18- Define communication protocols and integration standardsGame Selection Strategy:
1# Recommended game distribution for 4-6 person team:
2# Gambling Games (minimum 3):
3# - Blackjack (complex logic, good for advanced programmer)
4# - Poker (moderate complexity, card game expertise helpful)
5# - Roulette (simple rules, good for systematic programmer)
6# - Craps (dice games, probability focused)
7
8# Non-Gambling Games (minimum 1):
9# - Trivia Game (question/answer format)
10# - Word Guessing Game (string manipulation)
11# - Memory Game (list/dict management)
12
13# Casino Infrastructure (1-2 people):
14# - Main Casino class and game management
15# - Player management and account system
16# - Console interface and user experienceAfternoon Session (2-3 hours): Planning and Design
1# 1. Define Common Protocols/Interfaces (All team members)

47# - Naming conventions for classes (PascalCase for classes, snake_case for methods)
48# - Package structure organization
49# - Testing requirements per game
50# - Documentation standards (docstrings)Daily Deliverable: Team charter document with roles, game assignments, and integration standards.

"What will you work on today?",
"Any blockers or dependencies?"

31. Create feature branch: git checkout -b feature/blackjack-game
42. Make changes and commit frequently
53. Pull latest from main: git pull origin main
64. Resolve any conflicts locally

13# Merge conflicts happen - here's how to handle them:

15# 2. Communicate with team member whose code conflicts
16# 3. Decide together which changes to keep
17# 4. Test thoroughly after resolving
18# 5. Commit the resolutionCommon Pitfalls and Solutions

- Pull and integrate frequently
- Pair program on shared components
Pitfall 3: Insufficient Testing

Solution:
1# Test pyramid: Many unit tests, some integration tests, few end-to-end tests

3# Unit test (fast, isolated)

19 passThe Professional Mindset
This project teaches you skills you’ll use every day as a professional developer:
Team Collaboration: Working with other developers, managing dependencies, resolving conflicts
Version Control: Using Git effectively for multi-developer workflows
Testing Strategy: Unit tests, integration tests, test coverage metrics
Interface Design: Creating contracts between system components
Incremental Delivery: Building features in phases, integrating continuously
Code Quality: Writing clean, documented, testable code
User Experience: Building intuitive interfaces even for console applications
Final Thoughts
The casino project isn’t just about building games—it’s about learning to work as a professional development team. The technical skills matter, but so do the collaboration patterns, communication practices, and integration strategies.
Six months from now, when you’re on your first development team, you’ll use these exact same practices: daily standups, feature branches, pull requests, code reviews, continuous integration, and iterative delivery.
Take this seriously. Communicate well. Test thoroughly. Help your teammates. And build something you’re proud of.
Good luck, and may your code compile on the first try! (It won’t, but that’s okay—that’s what testing is for.)
