This website https://x.bluestacks.com/ is a cloud gaming site for android games, though it only has some games, it has some of my favorite games so I continue to use it, War Robots, and Lords Mobile. But I have found out a way to get more games than are listed in the website. Once you visit the site, sign up. Then, open up the game Dawn of Zombies: Survival. Once it has loaded a message will come up saying "You have to update the game" or something similar, click OK. Once you do this it will take you to the Google Play Store. Next, you can use the search bar to find the game you would like. Click download and wait for it to download. Then click play and there you go you can play the game.
Note: The devs behind this website might realize that one of their games is not on the latest version and update it, due to this, it will prevent us access to the Play Store. But I am pretty sure there are other ways to get to the Play Store from other games, I have managed to get to the Play Store through the game War Robots, but I don't remember how.
