When and why did it become a “mitzvah” to have a game featured at a Chanukah party? I have noticed that families try to outdo each other by coming up with the newest game. Yes, there is a minhag of playing draidel, but the games that people are playing today have no source in halacha or minhag. Chanukah is not the time to follow chukas hagoy!
As a side note, many of the “games” played lack in tznius and menchlichkeit, and end up causing much loshon hora and machlokes. “It’s only a game” is not an excuse to delve into other peoples private life and sholom bayis. Games like how well do you know your friend/spouse, hadwriting analysis, pranking etc. are unacceptable and inexcusable (even if “he’s my brother-in-law” or “she’s my sister-in-law” etc.).
