+## 📖 How to Play
+
+To win this game, you have to slide and combine tiles until you successfully create the **2048 tile**! 🏆
+
+### The Rules 📜
+- The game is played on the classic **4x4 grid**. (Keep an eye out for future updates that may introduce different board sizes to vary the challenge!)
+- Two tiles, either a '2' or a '4', will appear in random empty spots at the start.
+- With every move, a new '2' or '4' tile will appear in a random empty spot.
+- When two tiles with the **same number** touch, they **merge into one** tile with their sum. For example, two '8' tiles merge to become a single '16' tile.
+
+### Controls 🕹️
+- **Desktop:** Use the **Arrow Keys** (`↑`, `↓`, `←`, `→`) on your keyboard to move all tiles in that direction.
+- **Mobile:** **Swipe** up, down, left, or right on the screen.
+
+The game ends when the grid is full and there are no more possible moves left to make. Good luck!
