Yes, using fake money to gamble can also be a solution because if you want to continue gambling we don't need to deposit money directly, we can just enjoy the game without having to be afraid of losing and our finances will remain safe.
For those that have fell into an addiction I do not think this is going to be too helpful, and my reasoning for this is that since they developed a compulsion already towards gambling, anything that resembles it may trigger in them the desire to try their luck one more time.
So while using play money to gamble may seem to provide a solution for those people, instead it is just tempting them to go back to their old ways, and in that case it is better for them to give up gambling completely for good.
