Which action constitutes a felony related to an illegal lottery?

Promoting a lottery constitutes a felony related to an illegal lottery because lotteries are heavily regulated under state law and often require specific licenses to operate legally. Most jurisdictions define lotteries as a game of chance where participants pay for a chance to win a prize. When someone promotes a lottery without the requisite authorization or outside the bounds of legal statutes, this act transgresses legal boundaries, and thus can be charged as a felony.

In contrast, promoting a local fair, organizing a charity event, or hosting a bingo night may involve elements of chance or fundraising but typically do not violate laws concerning lotteries, provided they are conducted in compliance with local regulations. Charity events often have specific exemptions, while many states allow bingo nights under particular circumstances, such as non-profit fundraising. Therefore, it is the act of promoting a lottery, particularly when done illegally, that categorically falls within the felony designation.
