Slightly different but seems to work

I put the “while” before “PlayAgain”
actually using “PlayAgain” as the Boolean.
it does work , but will this cause errors later on?

Is there any side effects on that? do-while loop

If you mean any side affects to ‘cout << endl;’ at the beginning of every game loop, the short answer is no (other than the new line that’s created). Long answer is, it will depend on how your PlayGame function ends and starts. If PlayGame starts or ends with creating a new line then you might find that you have too much spacing. More importantly PlayGame will end in a Win or Lose state, if they aren’t consistent then you might get some odd spacing that could be missed while testing. Just be…

This discussion says it's fine,  I was wondering that myself. 

Is there a reason for the extra boolean variable? does that practice come in handy later on?

With out seeing exactly what PlayAgain() does it’s hard to say for sure. But in general, if you’re just prompting the user if they’d like to play again then this approach makes a lot of sense and is common practice.
