 ''public int[][] getBoard()'' returns the gameBoard.
 ''public int max()'' returns the maximum element of the gameBoard.
+===== Implementing Scoring =====
 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.
+===== A GUI Example =====
+Here is an example that implements the ''KeyListener'' class so the user can simply use the arrow keys to make a move.
+Modify the ''paintComponent'' method to change the fonts, colors, size, and appearance of the game.

+===== Making an executable jar file =====
+Any computer with the [[https://www.java.com/en/download/manual.jsp|Java runtime ]] installed can play your version of the 2048 Game.
+==== Using Eclipse ====
+  - From the ''File'' menu, select Export
+  - In the ''Java'' folder, select Runnable JAR file
+  - Press the ''Next'' Button
+  - Under the ''Launch Configuration'' your project that runs the GUI2048's ''main'' method
+  - Under ''Library handling'' select ''Extract required libraries into JAR''
+  - Select the ''Export destination'' (so you file the java executable later!)
+  - Press ''Finish'' button (even if you're American)
