Then maybe you should not think about the game, and about the service for earnings in the Internet. In third world countries there are many who want to have an income on the Internet. If you will provide them work and will from this have your interest, perhaps you will earn more? Think about it.
Thank you for advice. But I already created a faucet and it's not very popular, and also not very fun.
You have to think about games that haven't seen by anyone, or haven't played by anyone in any gambling sites here in the cryptocurrency world, because if you are just going to make something that is already here, then, it won't be that big and won't make any big impact at all. And you are right, Faucets are not that popular anymore because there is a lot of ways nowadays where you could earn bitcoin more than you could earn on a faucet.
