2048 is a single-player video game written by Italian web developer Gabriele Cirulli and published on play.google.com. The game is played on a plain 4×4 grid, with numbered tiles that slide when a player moves them using the four arrow keys. The objective of the game is to slide numbered tiles on a grid to combine them to create a tile with the number 2048; however, one can continue to play the game after reaching the goal, creating tiles with larger numbers.
The game begins with two tiles already in the grid, having a value of either 2 or 4, and another such tile appears in a random empty space after each turn. Tiles with a value of 2 appear 90% of the time, and tiles with a value of 4 appear 10% of the time. 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 game received generally positive reviews from critics, with it being described as "viral" and "addictive".
