🎮 Building the 2048 Game in Python — Logic, Algorithms & Implementation Guide

2048 game by Algorithm Alchemist

2048 is a simple yet wildly addictive puzzle game that challenges your strategic thinking. Developed originally by Gabriele Cirulli in 2014, this game has gained immense popularity for its simplicity and replayability. In this post, we’ll explore how to build the 2048 game using Python and understand the core logic and algorithms behind it.

🧩 What is 2048?

• The game is played on a 4×4 grid.
• Players slide tiles in four directions: up, down, left, and right.
• Tiles with the same number merge into one when they collide.
• The merged tile has a value equal to the sum of the two tiles.
• The goal is to create a tile with the number 2048.
• New tiles (2 or 4) appear after every move.
• The game ends when no valid moves are left.

📦 Data Structure

The game grid is represented using a 2D list:

grid = [
  [0, 2, 0, 2],
  [0, 0, 4, 0],
  [2, 0, 0, 4],
  [0, 0, 0, 0]
]

• A 0 denotes an empty cell.
• Numbers like 2, 4, 8, … 2048 represent the tile values.
