Since it is a game of chance, children are not officially allowed to participate in the game of bingo. Definitely not in the casino because you have to be of legal age there. At a beer festival in the country, you won't pay too much attention to it. As is well known, tickets are also sold to children there. From a legal point of view, it is not okay, but at least the parents who legally purchase the bingo card should be there. Mostly these are prizes that have been sponsored. In any case, children have no place in a real bingo game.
