This single-player puzzle game is a flash version of the hit game 2048, created in March 2014 by 19-year-old Italian web developer Gabriele Cirulli. Since Cirulli did not create the mechanics of the game, he refused to profit from it and released it as open-source. There are over thirty different versions or variants of the game on Kongregate. The objective of the game is to slide numbered tiles on a grid to combine them and create a tile with the number 2048.
2048 is about spatial logic and can be regarded as a type of sliding block puzzle. The game is played on a four by four tile grid, with numbered tiles that all slide in one direction on the board when a player moves them using the arrow keys. When an arrow key is pressed, all tiles slide as far as possible in the chosen direction until they hit either another tile or the edge of the grid. If two tiles of the same number collide while moving, they will merge into a single tile and the value of the new tile will be the combined value of the two tiles that collided. The resulting tile cannot merge with another tile again in the same move. Every turn, a new tile will randomly appear in an empty spot on the board with a value of either 2 or 4. Tiles of different value have different colors so the player can easily distinguish them. The game ends when no more moves are possible, which happens when the whole grid is filled and no tiles of the same value touch each other, so no tiles can be merged.
The game has a high-score feature and a scoreboard 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. The game is won when a tile with a value of 2048 appears on the board. After reaching the target score, players may choose to continue in order to get a higher score.
