Maybe there could still be a way to save faucets in all of casinos but I doubt it will ever happen, just to give an example, maybe there could be "play money" type of thing where it worths zero in real life unlike satoshis casinos give out for faucets, that way people could gamble with that fake money and get the fun of the website and they could actually end up liking the website thanks to it and deposit real money and gamble? Wasn't that the purpose of faucet? To show people what kind of website this is and make them gamble without risking anything before they deposit money?

Well, if that is the case people who do not want to deposit but first want to try, can do that with fake play money and after they decide if they like it or not they could deposit or not deposit depending on if they liked it or not.
