Let me get this straight, so there is other players involved, we all play in a lottery like game where we all click on the "play" for the next game and one of us that joined in there wins all the money put by everyone that joined minus the 15% house cuts for themselves?
I have only played the demo so far because it is brand new and I didn't wanted to risk my money just yet but I kinda understood what the game is from the demo itself. It is definitely different than many other places, it is both pvp which usually requires skill like playing poker but it is also luck based like dice because you have a shot at winning without doing anything but clicking play.
This game will either be amazing or horrible in the end, people like the pvp stuff but they also like the luck based stuff, so it could potentially be great. The design looks a bit off to me tho, too childish, maybe something more professional could have been done.
You've understood it properly.
Website design coupled with gambling should have a more relaxed design, perhaps in the future something will change in design.
