I was confused about the center die too at first. I was like “Do I try to click on the dice that match this ? Is there some sort of bonus doing that?” But as far as I can tell it’s just an image that changes to random dice roles.
I get why you put a die there. It’s thematically correct, but maybe change it so it doesn’t look just like the other dice. Or maybe when you get a logo fo r the game, use something like that.
