There’s a few variations, but the one I’m most familiar with is like go fish, except you don’t have to be honest if you have the card someone else asks for. I’ve played versions done with trivia, though where you have to determine if the answer given is real or bullshit (which would be more likely to turn into a game show). I’ve only done the latter like twice and I was drunk at the time so I don’t remember the exact rules. 🤣
