The "lucky" number is picked before the game starts.
There is no way to change the lucky number.
The lucky number is not picked (or at least the hash isn't displayed) until the first player purchases a ticket, but generally we are in agreement until here.
It is impossible for someone to get the lucky number even if they know what it is.
This is false. If the house knows the number is 10.000, for example, what stops it from waiting until new players are unlikely to join and then purchasing the winning ticket itself? The players would never know they've been cheated.
This is the weakness I'm addressing in my previous post.
Proof your a bustabit admin look at your other posts.
You guys need to just stop. I'm a competitor i get that but no need to be this ruthless.
Again: I do not own bustabit, nor am I an administrator or a moderator for bustabit. My one post in bustabit's thread doesn't make me a bustabit admin any more than my four posts in this thread make me an administrator of your game.
I also don't believe that pointing out technical issues qualifies as "ruthless" in any way.
