I have a project (in my signature) that is much newer and has much more views than some projects a few pages down in trending games, but there are still games like “Taco wizard under water” like 5 pages down on trending that have like 20 views and are like a week old. How do they figure this out? I can't even find my game even though it is getting like 80 views per day and Taco wizard under water is getting like 3 views per day.

Please tell me if there is some sort of formula to this.

They're kind of secret.

Well, there is a formula — projects under the Explore tab are placed there under an algorithm. However, most people don't know what the algorithm is, and I would say most Scratch Team members don't know, either. I don't know about it, myself, and I'm not sure we'd be interested in revealing it; otherwise, people might find ways to abuse it.
