In my opinion, it is more profitable to be a casino owner, but it requires a lot of initial capital. But I see that many forum participants choose the developer option, as it does not require a lot of capital, which most do not have, but many have programming skills.
The original question is about having one casino with multiple games vs having one game in multiple casinos.
I think in that regard, the best for me would be having one game in multiple casinos, that's assuming the game is a popular one.
But it's hard to know which games are going to be popular, which brings the idea that a casino with different games might be the best option.
But again, it depends, maybe in some casinos the game is not popular, but it is popular in other casinos.
