+# Interactive A* Pathfinding Algorithm Game
+
+## Model Overview
+
+An interactive educational game that visually demonstrates the A* pathfinding algorithm using PyQt5. This application provides a hands-on way to understand how one of the most popular pathfinding algorithms works through real-time visualization.
+
+## What is A* Algorithm?
+
+A* (A-Star) is a graph traversal and path search algorithm that finds the shortest path between nodes. It combines the strengths of Dijkstra's Algorithm (guaranteed shortest path) and Greedy Best-First Search (efficiency) by using both:
+
+- **g(n)**: Actual cost from start node to current node
+- **h(n)**: Heuristic estimated cost from current node to goal
+- **f(n) = g(n) + h(n)**: Total estimated cost
+
+## Features
+
+### 🎮 Interactive Gameplay
+- Set custom start and end positions
+- Place and remove obstacles in real-time
+- Visualize algorithm execution step-by-step
+- Adjustable animation speed
+
+### 🎨 Visual Elements
+- **Green**: Start node
+- **Red**: End node  
+- **Gray**: Obstacles/walls
+- **Yellow**: Open set (nodes being considered)
+- **Light Red**: Closed set (evaluated nodes)
+- **Blue**: Final optimal path
+
+### ⚙️ Technical Features
+- 20×20 grid system with 8-directional movement
+- Real-time cost display (g, h, f values)
+- Manhattan distance heuristic
+- Pause/Resume functionality
+- Reset and clear options
+
+## Quick Start
+
+### Installation
+```bash
+pip install PyQt5
+```
+
+### Run the Game
+```bash
+python astar_game.py
+```
+
+### Usage Instructions
+1. Select "Start Point" mode and click a grid cell to set start position
+2. Select "End Point" mode and set destination
+3. Use "Obstacles" mode to add walls
+4. Click "Start" to run the algorithm
+5. Watch the visualization and learn!
+
+## Educational Value
+
+This game is perfect for:
+- 🎓 Computer Science students learning algorithms
+- 🎮 Game developers implementing pathfinding
+- 🔍 Anyone curious about how navigation algorithms work
+- 💡 Understanding heuristic search methods
+
+## Algorithm Details
+
+### Heuristic Function
+Uses Manhattan distance: `h(n) = |x₁ - x₂| + |y₁ - y₂|`
+
+### Cost Calculation
+- **Movement Cost**: Euclidean distance between nodes
+- **Total Cost**: f(n) = g(n) + h(n)
+- **Node Expansion**: Always expands node with lowest f(n) first
+
+### Key Properties
+- **Complete**: Always finds a solution if one exists
+- **Optimal**: Always finds the shortest path
+- **Efficient**: Explores fewer nodes than Dijkstra's algorithm
