Is this a minhag or halacha? Having the  menorah burn for at least 30 minutes after   nightfall. Halacha. Yep. Halacha. Is this  a minhag or halacha? Saying Hallel. Yep,   you got it. Lighting the candles at a certain  time. Usually, I don't pasken, but in this case,   I would think it's a galactic thing. Yes,  it is. Not using the light of a menorah   for personal benefit. Halacha. Is this  a minhag or halacha? Eating fried foods. Yeah. Minhag. Is this a minhag  or halacha? Singing Ma'oz Tzur. Singing it? I feel like you have to say it,   but singing it is probably a minhag.  It's a minhag to say it in general.   Really? Giving money or presents. Minhag.  Yes. Playing dreidel. Uh, minhag. Yay. Is   this a minhag or halacha? Adding Al Hanisim  and benching on the Amida. Yep, you got it.
