                 Peg Solitaire Game
==================================================

Description
------------
This is a simple implementation of the classic **Peg Solitaire** game using HTML, CSS, and JavaScript. The game board consists of a 7x7 grid where marbles are positioned on valid spots. The goal is to remove marbles by jumping over them, with the objective of having only one marble remaining.

Usage
------
1. Click on a marble to select it.
2. Click on an empty cell two spaces away (horizontally or vertically) to make a valid move.
3. The marble will jump over an adjacent marble, removing it from the board.
4. The game ends when only one marble remains, and you will receive a congratulatory message!

Game Logic
-----------
- **Valid Move:** A marble can jump over an adjacent marble if there is an empty space two positions away in a straight line.
- **Winning Condition:** You win the game if you reduce the board to a single marble.
