Thanks so much for the info!! I want to learn code for games but right now I am really busy with my exam for college so I don't think I'll have the time for a while. On the other hand I think that one of those game studios where you don't need much information might be an option, as Rutin said:
This might be faster (I want to finish this in less than four months, at least the game if not the online multiplayer part) and also easier (is the 4 months part realistic?) . But if I make them in those studios will I be able to upload them on google play store, ios app store and browser (I ask that because from what I've seen each platform requires a separate language (android -Java, ios-swift etc and I don't know how the studio works and what the language will the games have)
Also I have to mention that the multiplayer part consists in a tournament game where people will play 1 v 1 and the winner will play against another winner and so on until one player wins. Will this be hard to do, and how much time would it take?
