The 2048 games are a popular genre of sliding block puzzle video games that challenge players to combine numbered tiles on a grid. The objective is to create a tile with the number 2048 by merging tiles of the same value. These games typically provide a 4x4 grid where players can slide tiles up, down, left, or right to combine them strategically. When two tiles with the same number collide, they merge into a single tile with the sum of their values. This mechanic encourages players to think critically about their moves to maximize tile combinations.
