GameBoardSquare 는 Mine 타입까지 이미 고려하고 있는것 같네요!
그것 때문에 NumberSquare도 MineSquare과 논리적으로 엮일려는거 같아요.

startIndexOfBoard와 board.first().size, board.size는 무슨 의미를 가지고 있는지 알기 어렵네요!

is로 시작하니, 리턴이 boolean 일것 같네요! require같은 이름은 어떨까요?

이 부분에서 이미 지뢰를 생성하고 있네요! 그럼 이 클래스 내에서 지뢰(MineSquare)를 담고 있는 List를 만들어서 관리해주면 GameBoardSquare에 isMine은 고민해볼 필요가 있겠어요!
