Ready or Not (2019)

A slightly supernatural uniting of the-wealthy-sure-have-absurd-mannerisms with the-most-dangerous-game tropes, a woman is marrying into a family that believes it is cursed to play a game between family and family-to-be on the night before any weddings. The game is selected by a vengeful ghost who, on occasion, chooses hide-and-seek-to-the-death. Guess what's on the menu for tonight?

They don't tell the bride she's being hunted to death, but she figures it out through their initial gross incompetence. Most of the help gets murdered violently by accident.

It's a cat-and-mouse game throughout a mansion with rich people using rich people toys and the stereotypical rich person family drama. Quite a few times they forget they are mid-chase and stop to argue, or forget that they just saw her run into the room next door just moments earlier.

She wins and they all blow up from phantasmic curse.
