2048 is a puzzle game typically played on a 4x4 grid. The objective of the game is to merge tiles with the same number to create a tile with the value of 2048. The game randomly generates new tiles on the grid as the player moves them.

The rules of the game are as follows:

1. **Initial State**: At the beginning of the game, some tiles are randomly placed on the grid. These tiles usually have values of 2 or 4.

2. **Movement**: The player can move the tiles up, down, left, or right on the grid. When the player moves, all tiles move in the same direction, and empty spaces are filled.

3. **Merging**: When moving, two tiles with the same value can be merged together. For example, merging two tiles with a value of 2 creates a tile with a value of 4. Each merge operation earns points.

4. **New Tile Generation**: After each move, a new tile is randomly generated in an empty square. Typically, these new tiles have values of 2 or 4.

5. **End Game Condition**: The game ends when no more moves can be made on the grid. In this case, if the player has not achieved the 2048 tile and there are no empty spaces left on the grid, the game is over.

6. **Scoring**: Points are earned for each merge operation during the game. As the player progresses and obtains larger tiles, their score increases.

Under these rules, the player's objective is to achieve the highest score possible and ideally create the 2048 tile. However, success in the game requires strategy, planning, and attention.
