Questions tagged [2048]

2048 is an open source tile-based puzzle game. Questions with this tag should be either about implementing the game or implementing solving strategies. Ask on https://gamedev.stackexchange.com/ if it's a specific game development issue. Ask on https://gaming.stackexchange.com/ if it is about playing the game.

2048 is an open-source app created by Gabriele Cirulli, an Italian developer, as a clone of 1024. The game is a 4x4 grid that starts out with two tiles. Each tile is either a 2 or a 4. When the player swipes either up, down, left, or right, all of the tiles move in that direction and a new tile appears in a random spot. When two tiles of the same number are pushed together, they merge and form a new tile with twice the value. The object of the game is to form at least one tile with a value of 2048.
