+# Math Rush (Addition Challenge GUI)
+
+**Language:** Python  
+**Run:** `python3 math_rush.py`
+
+## 🎮 Description
+Math Rush is a fun and interactive GUI-based math game where players solve random addition problems under time pressure.  
+You have **10 seconds** to answer each question correctly — how fast can your brain calculate?
+
+## 🕹️ Controls
+- Type the correct answer in the box and press **Enter**.
+- Each question has a 10-second countdown.
+- Game ends when you’re too slow or answer incorrectly.
+
+## 📦 Requirements
+- Python 3.8+
+- No external libraries (uses Tkinter, included with Python).
+
+## 🚀 How to Play
+1. Run the script:  
+   `python3 math_rush.py`
+2. Click **Start Game**.
+3. Add the two numbers before time runs out.
+4. Try to reach the highest score!
