In the UK there are regulations that require casinos and other gambling venues to block access if a problem gambler doesn't show restraint. It's much like how we would expect a barkeeper to tell a alcoholic who has had too much that they won't be served more and shouldn't drive home.

Similar addictive behaviour occurs with these apps and the games are designed to be as addictive as possible. While users should take personal responsibility, it would be trivial for these app producers to provide users with some protections from themselves.
