2048 Game in Racket

This is an implementation of the 2048 game in Racket, a dialect of Lisp. Feel free to play around!

Getting Started

Prerequisites

• Racket (Make sure Racket is installed on your system)

Running the Game

1. Clone the repository:

   git clone https://github.com/yourusername/2048-racket.git

2. Navigate to the project directory:

   cd 2048-racket

3. Run the game:

   racket main.rkt

How to Play

1. Use the command line to input your moves:
   • w: Move tiles up
   • a: Move tiles left
   • s: Move tiles down
   • d: Move tiles right
2. The game will print the board and your score after each move.
3. Combine tiles of the same number to create larger numbers.
4. The game ends when no more moves are possible.
