No matter how tired they are, they royals are reportedly expected to stay up and play the game until Her Majesty says that she has had enough. And, if they retire early they risk upsetting her.
We don’t know about the royals, but we certainly wouldn’t take that chance!
What’s more, her bedtime rule is isn’t the only one the royal family have to follow over the festive holiday.
When it comes to opening presents, The Queen has three very specific rules.
Firstly, nobody can open their presents until Prince Philip gives them the nod to do so. Next, presents must involve “gag gifts” and finally, the cheaper the better when it comes to presents.
Previous presents have reportedly included a grow-your-own girlfriend kit given to Prince Harry by Kate, Duchess of Cambridge before he met Meghan and a leather toilet seat given to Prince Charles by Princess Anne.
