• There is a ToString() method that overrides the built-in method. This method marks rows as numbers and columns as letters.
• There is a RemovePawn() method that removes pawns from the specified position.
• There is a MovePawn() method that moves pawns from a specified position to another field.

• - There is a method that checks if the starting position from user input is a valid pawn and if the ending position is within board boundaries. If so, it calls TryToMakeMove() on pawn instance.

Optional Tasks

• Try to implement the singleton pattern. Try to implement additional features such as crowning, multi-jumping, and checking for draw.
• The Board is a singleton, so it can have only one instance.
• The Crowned feature is implemented. There is a property on Pawn called bool IsCrowned that returns true if a pawn is crowned and it implements crowning rules.
• The Pawn class can check if it can make multiple jumps according to the rules.

• - There is a CheckForWinner() method that checks whether there is a winner after each round.
• - The CheckForWinner() method also checks for draws.

There is a Pawn class.

• - There is a Color Color property that returns the color of the the pawn (white or black).
• - There is a (int x, int y) Coordinates property that represents pawn coordinates on a board.
• - [Extra] There is a bool IsCrowned property that returns true if a pawn is crowned.

There is a Game class that contains all game logic and actions.

• - There is a Start() method that starts game between players.
• - There is a Round() method that determines one-round actions, that is, checks which player is next and whether there is a winner.

• - The Pawn class contains a method that validates the move (whether it is within the game rules) before it is performed.
• - [Extra] The Pawn class can check if the pawn can make multiple jumps according to the rules.

There is a Board class that represents the square board of Polish draughts.

• There is an n parameter in the constructor that specifies the side length of the square. The size must be an integer between 10 and 20. It is provided as user input.
• There is a Pawn[,] Fields 2D array that represents fields on a board. Each field can be null (empty) or a Pawn instance.
• Pawns are created and placed on every other field when the board is initialized. Their number is determined by board size, as a 2 * n.
