Gameplay

A Player gets a turn [ Game.play() ]

Player makes a plays a turn and returns the played ‘move’ to Game Player.playTurn()

Game delegates the move validation processing to the moved Piece instance, passing destination-block and board instances. ( Piece.isValidMove(...): boolean )(Board instance is required to check is a piece lies in path of the move)

Piece calculates validity of the move and returns a boolean to Game

If move is valid, GameController

• updates location of Piece on board (Game.updateBoard(...))
• checks if move has performed any kills ( Game.checkKills(...))
• checks if any of game terminations conditions are valid ( Game.isGameOver(...))
