C++ Project on Shuffle Game

Shuffle Game

A C++ console and graphics program that presents a 3x3 number puzzle. The player must arrange numbers in ascending order by pressing number keys. The game uses Turbo C++ BGI graphics.

How to Play

• Press 1 to start the game.
• Press 2 to view the rules.
• Use number keys to move tiles.
• Press X to exit the game.
• Arrange all tiles in ascending order within 50 moves to win.
