There are 4 possible moves:
“Left to Right” – Right arrow key.
“Right to Left” – Left arrow key.
“Top to Bottom” – Up arrow key.
“Bottom to Top” – Down arrow key.
With every move a new tile (with a value of 2 or 4) randomly appear in an empty spot on the board.
Tiles slide as far as possible in the chosen direction until they are stopped by either another tile or the edge of the board. If two tiles of the same number collide while moving, they will merge into a single tile with their sum value – e.g.: 2 and 2 becomes 4, 4 and 4 becomes 8 and so forth.
The resulting tile cannot merge with another tile again in the same move.
The game is over when the board is full and there aren’t any possible moves left.
In order to reach the mythical 2048 tile, the player must play strategically and maintain enough room on the board to achieve the tile.
