A variation of Asher Vollmer and Greg Wohlwend’s Threes, 2048 is a puzzle game in which you have to join the tiles together until you get a 2048 tile to win. According to the author, his version is based on other similar games which also drew inspiration from the iOS masterpiece. 2048 supports both keyboard controls and swipe gestures, hence if your mobile device has a large enough screen to display the page then you can even play it while being away from your desk.
The concept of the game is pretty much the same as Threes: you slide tiles using the arrow keys (or your fingers) to merge similar numbers together. Each move you make causes another tile to appear on the board, and you lose when the entire board is completely filled with tiles.
Gabriele Cirulli’s version of 2048 is available to play here.
