2048 is a popular single-player puzzle game that challenges players to combine numbered tiles on a 4x4 grid to reach the tile with the number 2048. Players slide tiles in four directions—up, down, left, or right—causing identical numbers to merge and double in value. The game requires strategic planning, as the grid fills up quickly, and running out of moves results in a loss. With its simple mechanics yet deep strategy, 2048 has become an addictive and enjoyable brain-teasing game available on mobile devices, web browsers, and computers.
