However, my concept isn't gambling since the game I am trying to develop is more on brain-type in the form of quizzes.
I think you missed my point. You are talking apples and oranges. It doesn't matter what the game is, if you are going to eventually pay people more than others, you will need to tread carefully to avoid gambling restrictions.
You could raise money by
forcing people to
donate to you. Depends on if you are a sociopath.
Correct me if I'm wrong. Does other existing mobile games in Android and iOs like Clash Royals, PubG mobile, Ketchapp games, etc. also consider upgrading to premium membership as "donation" to remove ads? Or buying a champion in League of Legends? Kinda confused.
These games I've mentioned are also having their own small and big tournaments too.
For me, a common reason would be transparent P2P transactions. Like in-game rare item trading for example. A player wants to trade a rare item with you for a certain amount of virtual gold while in-game. Once the transaction is complete, the transaction hash was created on the game's blockchain with an accurate timestamp proving that the two parties have traded rare items for some virtual gold, etc.
how is that different from what Steam does?
lets say you are playing Dota2 and have found a rare big ass sword. you go to steamcommunity and put it up for trade. i've only seen item with item trade but i believe it is possible to sell for steam dollar too.
if you want to make it more P2P you can turn the user's device into a node where it could connect to other players and they could show each other the items they have and trade them with in-game money or other items.
still no need for blockchain.
We're talking about in-game trading, not outside marketplace. Steam is a platform for all games, but I am referring to transactions while "inside the game".
As what I have shared in my
reference earlier (scroll down to P2P gaming transactions, second paragraph), this is one problem that most gamers are experiencing nowadays, in which blockchain could solve.
