How to earn the first money on the game without donation?

Question

Android

I am making my first logic game for mobile platforms, there will be no donation in it.
As you progress through difficult sections, there will be points to save, if the player passes near the point and dies a little further, he will automatically respawn at the save point.
I thought to place an advertising banner in the menu when choosing levels or when a player dies, but what if everyone plays it with the Internet connection turned off or will they patch it?

Answer 1

Chvalov : As practice shows, active users never turn off WIFI. And 3g has long been a popular thing. If your advertisement is not <<maddening>> then it may appear after death. This practice is often used by KetchApp.
In general, I advise you to go over similar games and see how they implement it.
Better yet, think about how you will market your game. If no one knows about it, then advertising <<anywhere>> will not bring you income;)

Answer 2

You can make two versions of the game paid and free. in paid more levels.
in the free one you can also advertise, in the paid one you can't.
