People going to casino with a genuine belief that they will win.

Casino — a business specifically mathematically engineered to make sure that nobody wins against a casino, to maximize your losses, and to make money from it. By the very definition, nobody "wins" against it. Yet, some people still come and play.

Same thing with google pocket slot machine — the very reason they link the game to your bank account is to milk money from you, or god forbid, your children.
