Joseph, that’s silly everybody plays checkerst. That’s not a JEWISH practice.
Im sure some will insist playing cards on chanukah is a minhag.
Some will insist cards and or chess are a minhag on nittel.
All of us would say (I think) that spinning a four-sided top on chanukah is a minhag.
Which brings me back to my question, at what point do these become a minhag?
Is eating cholent on shabbos (specifically, not just hot food) a minhag?
