Implement Freecell Game Mode

[eliasdorneles]

Goal: To extend the existing Klondike solitaire game implementation to support the Freecell game mode.

Proposed Approach:

1. Refactoring for Generality:

   • Card Class: Ensure the Card class is designed to be versatile, capable of representing cards in various solitaire games. Consider adding properties or methods that might be relevant to different game rules, such as potential moves or restrictions.
   • Game Class: Create a base Game class that encapsulates core game logic, such as dealing cards, checking for valid moves, and managing the game state. This class should be designed to be flexible enough to accommodate different game rules.
   • Specific Game Implementations: Subclass the Game class to create specific implementations for Klondike and Freecell. Each subclass will override methods to implement the unique rules of its respective game.

2. Implementing Freecell:

   • Game Rules: Freecell is a solitaire card game where cards are dealt into eight columns. Four additional cells are available for temporary card placement. The goal is to build up four foundations, one for each suit, from Ace to King.
   • Game State: The Freecell game state should include:
     • Eight columns of cards
     • Four empty cells
     • Four empty foundations
   • Move Validation: Implement rules for valid moves in Freecell, such as:
     • Moving a card to a foundation if it's the next card in sequence and of the same suit
     • Moving a card to an empty cell
     • Moving a sequence of cards to an empty column or cell, following specific rules about the sequence's length and the number of free cells and empty columns
   • Game Logic: Implement the core game logic for Freecell, including dealing cards, checking for valid moves, and handling player input.
   • User Interface: Update the user interface to accommodate the specific layout and rules of Freecell. This may involve adjusting the number of columns, the size of the cells, and the visual representation of the cards.

Additional Considerations:

• Testing: Write comprehensive unit tests to ensure the correctness of the Freecell implementation.
• Performance: Optimize the game logic and user interface to maintain smooth gameplay, especially for larger game states.
• User Experience: Provide clear instructions and feedback to the user about the rules and the current state of the game.

By following these steps and considering the specific rules of Freecell, we can successfully extend the existing Klondike implementation to support this popular solitaire game.

@dev-intern-ai let's start by refactoring the code to make it possible to extend it. Can you make a first PR with that?
