What happens if nobody gets the exact number rolled? Are you going to continue to roll in that case until a number's hit, or are you just going to pick the closest number to the rolled one?
A demo would also definitely be nice to see; is this game provably fair as well? Most people won't play games that aren't provably fair online, would certainly be nice if something of the sort is implemented in the game you're giving away.
That would take some time before it hits the exact number that the participants choose. I think the code that the OP created can be use but needs an upgrade to recommended liking to player. I'll join too, who knows who can get the code. My number is 9191.
