How to make a Bot for a mobile game on iOS/android?

Question

Mobile development

Greetings habrochan, there were questions from the category "how does it work", "how much does it cost" and "how can I do the same, but for a different game". This is the case - there is a game called The Great Sultan, and for it a certain craftsman made a bot that will collect resources for you and stuff like that (I won’t give a link, otherwise you’ll think it’s advertising), it’s not difficult to find a bot. So I wonder how it works and if you order from those who know how much it will cost? The game for which you want to make a bot almost one to one licked copy. If you do it yourself, what do you need to know, what kind of jungle to climb into?
Thanks in advance for your replies.

PS How the bot works
This is the site on which I enter the mail (why? I don't know)
You also need to enter a referral code (it is given in the game, my game also has such a function)
And this is how I understand this code here the main link. In fact, I didn’t understand anything about how it all works)
