Is it possible to sell access to content in a mobile application?

Question

Android

Let's say there is a mobile application - a search game in reality, there is a web site. The essence of the question: can I get access to this game itself (not to additional features) using pre-generated codes (6-7 digits) It turns out that the user buys this code on the site and enters it into the window in the mobile application as a key. I'm more interested in how Google play and the App store will react to this. Thanks for any replies)

Answer 1

according to the rules it is impossible, but if you do not send to the site from the application, it is possible to pay for the same InApp, then it is viable
