I would be OK with it but I'm not the only parent with a child in the class.
It's a good game to encourage logical reasoning such as assessing probabilities, predicting outcomes, and developing strategies to strengthen logical reasoning and decision-making skills. And the kids do it in an interactive, social, and fun way that can improve communication skills, as students explain their reasoning and interact with peers.
BUT: teachers have to be careful with the methods they choose since some students or their parents may feel uncomfortable with gambling-related games due to personal, cultural, or religious beliefs. And even if the chance may be small that the children get addicted you probably should avoid money-related games just to be on the safe side. At least when the students are minors.
