While all these "tricks" and "engagement" chasing things are true, that's just mobile gaming in general these days. It has nothing to do with whether they ran "fake ads" or not. Most successful mobile games are stuffed full of loss aversion, fomo, "time saving", and "fake sale" monetization.

They're not making fake ads to get you into those systems. The games just do that and the ad you clicked was trying to see if you were interested in the game in the ad. Even if the game you were linked to doesn't match.
