Code Breach: The Tower Defense Coding Game
Welcome to Code Breach, where you're not just solving coding problems - you're infiltrating corporate databases and data fortresses! In this unique tower defense game, you'll face waves of enemies representing code barriers and security systems. Your mission? Break through these barriers by solving DSA (Data Structures and Algorithms) problems similar to those found on LeetCode and even including actual LeetCode problems.
Choose your hacking language of choice - Java, JavaScript, Python, or C++ - and build your solution tower by tower. Each tower represents a programming concept (like loops, conditionals, or functions) that you can use to construct your solution. The final wave's difficulty is determined by whether your solution passes all test cases - fail, and you'll face an overwhelming final assault!
And when you need help, our newly enhanced Hack Assistant is at your service. This AI-powered companion provides tailored assistance based on your needs:
- Hints Only: Get subtle guidance without spoiling the solution
- Full Solution: When you're completely stuck, get a complete working solution
- Step-by-Step: Break down the problem into manageable chunks
- Debug Mode: Get help identifying and fixing bugs in your code
- Learning Mode: Deep dive into the concepts and techniques used
The Hack Assistant has been completely revamped with our latest AI improvements, providing more precise, context-aware assistance that adapts to your chosen assistance level. Whether you're a beginner looking for guidance or an experienced coder seeking optimization tips, the assistant will help you breach those corporate defenses!
Tower Defense AI Integration
Code Generation System
- AI-generated code snippets for tower behaviors
- Dynamic difficulty adjustment
- Personalized challenge generation
- Smart hint system

Implementation Details
Our AI service has been completely revamped to provide more precise and context-aware assistance. Here's how it works:
// Core AI service structure
class AIService {
constructor() {
this.client = new AzureOpenAI({
endpoint: process.env.AZURE_OPENAI_ENDPOINT,
apiKey: process.env.AZURE_OPENAI_API_KEY,
apiVersion: "2024-02-15-preview",
deployment: process.env.AZURE_DEPLOYMENT_NAME || "gpt-4o"
});
}
}
The service uses different system prompts for various use cases:
- Hints and guidance
- Problem generation
- Code solution generation
- Code refinement
- Tower Defense snippet generation

More on Problem Generation: Our advanced problem generation system empowers users to not only create custom programming challenges, but also to fully control the problem creation process. After generating a problem, you can review and edit every part of it—including the description, function signature, test cases, and even the expected outputs. To ensure quality and fairness, you must also provide a working solution for your problem, which is automatically tested before you can submit it to the platform. If you get stuck, you can use the integrated AI chat assistant for hints, debugging help, or even step-by-step guidance to solve your own problem. This makes the process both educational and interactive, whether you're learning or challenging others.
More information and an interactive demo of this feature are coming soon—stay tuned!

Interactive Demo: Build a Solution (Tower Defense Style)
Notice how the old and new snippets generated are different, you can see that the old snippet generation would at times give a whole solution but the new snippet generation will actually give you the proper code for the programming concept you are trying to add to your solution.
Need help? Use the Hack Assistant (below) to get hints, step-by-step help, or even a full solution!
LeetCode Problem: Two Sum
Given an array of integers nums
and an integer target
, return indices of the two numbers such that they add up to target
.
You may assume that each input would have exactly one solution, and you may not use the same element twice.

Technical Implementation
AI Service Architecture
Our AI service is built with modularity and extensibility in mind:
const SYSTEM_PROMPTS = {
hints: {
role: "system",
content: "You are CodeGrind's AI teaching assistant. Your role is to help users learn programming concepts and problem-solving strategies, but never to provide direct code solutions."
},
problemGeneration: {
role: "system",
content: "You are a programming problem generator for CodeGrind. You're designed to create high-quality programming problems in JSON format."
},
// ... other specialized prompts
};
