Gamble for free? How are you going to gamble for free ?
Haha gambling for free, this is only applicable if you'll gamble with casino's play money.Gambling is risking your own money and if you are referring gamble for free as in faucet money thats not even a gamble. If you are not risking anything, thats bullshit for me. You only have very small chance to win but that is enough I think because it is gambling afterall isnt it
Faucet is one of it and this is what I've done before but giving this idea to the gamblers that wants to give up gambling, you'll encourage them instead of quitting. 
Nothing is free in this world as rightly being said. Even if you think you are getting it free their would be some condition apply scenario and thus you will fall in a trap and that free money will become the debt as you will play more to get more money and may end up in a losses .
How come that getting a free money will become a debt?
Technically, the money that you earn from faucets have a trade-off, which is effort and time. It may be considered as an easy-money but you still committed time on it.
Obviously, there are things in this world which are free and are not. The air, sunlight, shade from a tree, or any natural resource which man did not create are free. About the free money scheme, it still isnt free as like I said, you used time and effort in order to get it.
Gambling is more than money, rather it affects the attitude and mindset of a person wherein it draws your inner desire to gamble more despite what the result may be.
Simple as that.
