Freebitco.in is the answer, they have a faucet and they are the oldest casino that gives a small amount to their user per hour, a small satoshi that you received, by answering the captcha you will have you 2-3 digits of satoshi.
However, I saw ads on my social media about the games that offer play to earn like the online game Special Force Rush which I did not try it yet. I think it seems that game is a little bit interesting.
Freebitco.in doesn't always give 2-3 digits of satoshi anymore, but it's only 7 satoshi at the current rate. Yes you can earn more if you hit specific number when you roll your lucky number, but it's only little chance you will get higher than the 0-9885 number.
Those play to earn games aren't really to earn since you need to have capital to invest on their games/projects/items in order to earn. There's nothing different like you invest on shitcoin, moreover you need an effort and time to play.
