A game about matching numbers. Choose coordinates to clear said location and all neighbours of the same color.

Stores the data contained in a single game board. Most important methods are:

Should be used only once in every Board, right after creation. Populates the Board randomly with every color in Color, except Blank.

Get and set row at position i (zero-indexed) respectively.

Same, but with columns.

Same, but with single items.

Groups all Blanks in column j at the top, and any other items at the bottom, without changing their order. column_compacted does not alter the actual board data, while compact_column does.

Applies compact_column() to every column in the board.

Reports data about a Board. Most important methods are:

Returns all neighbours of item (i, j): two if (i, j) is a corner, three if it is a side and four otherwise.

Returns all neigbours of (i, j) that have the same color as it. Blank items have no friends, by definition.

Core function of BoardAnalyst. Returns (i, j), plus all friend neigbours of (i, j), plus all friend neighbours of said neighbours, to the infinity and beyond...

Returns the score associated with a list of items. Score varies based on the length of the list. Assumes all items in the list are friends.

Returns True if there is any item in the board with friends (a.k.a. if the game can continue)

Runs the game in console mode. Execution flow is as follows:

1. show_main_menu is called. It shows three options:
2. New game: calls start_new_game 1. Asks the user for his name 2. Creates a new Board, randomly filled, and an Analyst for that board. Then calls play_game.
   While there is something to be played:
   • Print the board, ask the user for input. Only two inputs are valid: the exit string or a coordinate with friends and that is not Blank. Any other input displays an error message and repeats.
     The exit string terminates the loop.
   • If the player entered coordinates, the score is increased and the board is updated. the new score is shown to the user.
   • The loop is repeated.
   3. When play_game returns the score of the game, calls print_game_over, which prints the player name and score.
   4. Control is returned to the main menu 2. About: calls print_about and returns to main menu 3. Exit: Prints personalized message to player (only if name is set). Then exits.

Runs the game in graphical mode. Execution flow is as follows:

1. MainMenuWindow is created, with three buttons:
2. New Game: Creates NameWindow, which asks the user for his name. NameWindow then creates a Board, an Analyst and a GameWindow, which has two kinds of buttons:
   • Coordinate buttons: These buttons are colored. Clicking on them updates the score, the board and the buttons, if the button corresponds to an item with friends; and does nothing otherwise.
   • End game button: Finishes the game and creates a GameOverWindow, which shows the player name and the achieved score.
     • GameOverWindow has a single button, which creates a new MainMenuWindow, resetting the execution flow to point 1.
3. About: Creates an AboutWindow, which has a single button that creates a new MainMenuWindow, resetting the execution flow to point 1.
4. Exit: Only if name is set, creates a GoodByeWindow, which shows a personalized message to last player. Then exits.
