How to legalize the income from the developed game?

Question

Law in IT

There are many games (in particular, browser-based strategies) in which players can both deposit real money and withdraw from the game (multiplying them in the game).
I want to make a game like this, but how do I formalize it?
UPD:
does this somehow relate to the gambling business (which is prohibited in the Russian Federation)?

Answer 1

As usual - create an individual entrepreneur or LLC
