What is the ruling on financial profit from an application based on downloading games, some of which are games of chance, while not playing the games of chance?

It is permissible to sell points acquired in games if the game itself is permissible. As for games of chance, such as gambling, they are forbidden if they involve monetary risk between players, where the money goes to the winner. This is considered one of the major sins, and it is not permissible to play them or sell their points.
