  0. Go to http://gabrielecirulli.github.io/2048/
  1. Copy & Paste below 3 lines to the console.
  2. Every time a move is done, a prompt will be opened.
  3. Input two integers (separated by a slash), where
    the first integer indicates the place where the tile will appear,
    and the second integer indicates the type of the tile (2 or 4 only).
    The place will be indicated by the index in the list of empty tiles (after the move),
    where the first one is leftmost+upmost and the next one is below of the first one.
    (For example, if every tiles are empty, then the tiles will have index 0 4 8 12 / 1 5 9 13 / 2 6 10 14 / 3 7 11 15.)
