2048

- 2048 is a single-player sliding block puzzle game

- 2048 is played on a gray 4×4 grid, with numbered tiles that slide smoothly when a player moves them using by finger touch.

- Every turn, a new tile will randomly appear in an empty spot on the board with a value of either 2 or 4.

- Tiles slide as far as possible in the chosen direction until they are stopped by either another tile or the edge of the grid.

- If two tiles of the same number collide while moving, they will merge into a tile with the total value of the two tiles that collided.

- The resulting tile cannot merge with another tile again in the same move. Higher-scoring tiles emit a soft glow

- A scoreboard on the upper-right keeps track of the user's score. The user's score starts at zero, and is incremented whenever two tiles combine, by the value of the new tile.

- As with many arcade games, the user's best score is shown alongside the current score.
