Make a 2048 tile!

The game is played on a 4 x 4 board and the player starts with two number 2 tiles.

Each turn where the player makes a valid move, another number 2 tile is added to the game board (a valid move is moving the tiles, or combining tiles). If you try to move in such a way that no move is completed, a turn is not registered and no new number "2" is added to the board.

You make new tiles by combining the tiles already on the board. Combine 2 and 2 to make a 4, combine 4 and 4 to make an 8 and so on, combine a 1024 and 1024 to make a 2048.

Game over occurs when the board is full and you no longer have a valid move available (ie no way to move or combine tiles).

It sounds way more complex that it is.
