I$\text{'}$m trying to make a basic solitaire game but I can't figure out how to implement the game to know what moves are invalid like which cards can be moved to which pile and how to implement a function to be able to move the cards to foundation piles. Also can't figure out how to implement the drawing of cards from the main deck. Here is what I have so far.
