Faucets are not as popular as they were before. Main reason is ad-sense. In the past, faucet owners were able to make very good profit from adsense and therefore they were able to pay high amounts to their users. This is not the case today. Now, only well known old faucets are able to recieve good traffic. I am not sure why, but this is exactly what new faucet owners should ask their selves. It is hard to become a popular faucet with same concepts over and over again. New faucets should be either as good as, or come up with new ideas. For example, new faucet games are really something we are missing today. Some old users here might remember farmsatoshi site(although it disappeared in the end). I hope we can see similar things soon.
Maybe there aren't so many games because faucet creators are newbies programmers. I liked that FarmSatoshi game too, but that was a Ponzi scheme in the end, people were spending a lot of time trying to fully upgrade their farms and most users (like me) just have lost their time. It would be only possible to create a popular game again if it were a real nice game, that people would want to play not only to earn money, but to have fun too. But developers won't want to spend their time and effort to create something that they will have to pay people, they want people paying them to play.
About this faucet, the rewards are too low, as I see DOGE faucets offer 0.1 DOGE minimum reward, on this faucet it's the maximum reward and there is only 10% chance to get it. The faucets beginning is important, if you don't invest some money to pay initial users there won't be enough traffic later to keep it running.
