My inlaws do this too!!!!
Its an after dinner thing and you keep the card from the deck if you get it right?
I actually was sick of doing them so one Christmas gifted them a pack of 90s questions (ie ones i could actually answer) and suggested we play the new deck as everyone learns the answers on the old deck after a while. The younger folk were on board and now we have 2-3 decks in play and when it's your turn you pick what deck/category you want.
Or buy a totally different after dinner game and politely insist you play.
Separately I have learned to do what i want at inlaws without "creating a scene"
So i take myself off for walks "to take a call from a friend who is having a hard time". I book nail and massages and pop into town for a few hours. I fancy something specific as a snacl and go to tescos for 90 mins. I go up to the room and crush candies "for a lie down" as i am a terrible sleeper and didnt sleep well...
I also send my husband up to them alone every second trip or so, i havent been there myself in 18 months (thanks covid)
It gets a lot bit of cats bum face from MIL but i am past giving a shit. Appearances are all and she'd look bonkers if she kicked off as they go to no effort and plan nothing when we visit so she'd be insisting i sit downstairs in their dark dusty living room in staid silence.
In this instance i would go for something they can't argue with too much.
"I feel terribly unwell and need a lie down so sorry please excuse me" (headache, indigestion, exhastion as slept terribly the night before)
"I need to phone great aunt fanny she is spending Christmas alone. She'll want a big long chat i'll pop out of the way. go on and start without me!"
That sort of vibe.
