The AP Classroom 2048 is Text based, so here is an example of a GUI that you can use with your 2048 Lab solution.

public int getScore() returns the score. public int[][] getBoard() returns the gameBoard. public int max() returns the maximum element of the gameBoard.

For the score to function the usual way, you need to modify each of the four merge methods in the Game2048 class. Whenever two cells combine, add this number to the score. For example, if two 8's are combined, 16 should be added to the score.
