__iter__ method for all Board instances

I'm having problem to implement iter method in challenge make all Board instances iterable... I have tried the same method as shown in the Emulating Built-ins video previously in this course.

boards.py 
class Board:
    def __init__(self, width, height):
        self.width = width
        self.height = height
        self.cells = []
        for y in range(self.height):
            for x in range(self.width):
                self.cells.append((x, y))

        def __iter__(self):
            for item in self.cells:
                yield item

class TicTacToe(Board):
    def __init__(self):
        super().__init__(3, 3)

I guess that I have figured it out... I just put the

def __iter__(self):
   for item in self.cells:
      yield item

method in the TicTacToe class and it worked.

The question is why the previous solution didn't work? Shouldn't the iter method be inherited by the subclass?
