The way is free to buy any in-game currency (money, diamonds, resources, etc.). Actual for any games, but first of all those where all the data of the accounts are stored on the server of the game. And these are all the top games from the Play Market.

Such games are useless to crack, no fandom geymhakery, lacquer patchers and others do not work there, only donat. In my way, the donut turns out to be free, but in the game it is counted as bought. The purchase takes place according to all the rules, there is no ban.
You can comfortably play any donated games, be in the top, quickly develop, tear all :)
