Short description
			
2047 is a remake of 2048, created for the "NOMAM Basic Ten-Liners 2014" competition. The entire code, written in the Turbo Basic XL language, is 10 lines long. The game takes place on a 4x4 grid and begins with one tile with the number 2. The player uses arrow keys to move the tiles, with a new "2" tile appearing after every move. When two tiles with the same number collide, they combine into one tile with the next power of two, e.g. two tiles with 16 will give a 32 tile. The goal is to get as valuable a tile as possible. The game is over if the entire board is filled. Link to description source
