About the house edge will be %1. I know I have to provide different things to users. If I won't do that, people probably prefer to Bustabit.
Well, it's not difficult for you, you can take a basic game that anyone understands, that is not something complicated and from there you can do something different, something that everyone likes and that has a lot of traffic, remember the example I gave you of freebitco.in, they competed only with their dice, and for the moment it was the only thing they had, plus the raffles, because it always excited people pariticpar, but now they can do something similar only because with another game, something that incites people come in and play it, and make it fun, something that even a child can understand just by looking at how it is played, it can be with art, or something that is very basic, as long as you can influence many people enter, and make it super original, that you have programmed yourself with a 2fa factor, something like that.
