Hi pythondeveloper! We would strongly advise against including gambling content in the game as that is a mature subject. Sorry for the miscommunication!
Hey, so in my game there are two types of cards: common cards and luck cards. One of the luck cards is called “Stock Market,” which gives players a 60% chance to gain money and a 40% chance to lose money. The card also costs in-game money to use. Would that be considered gambling?
