You said to PM you, so I am.
I just wanted to mention about the "leader" part, I had edited that out before you even replied. This is shown by the time of your reply versus the time of when I edited that post. I realized that part was a little mean and edited that out for that reason.
I brought up the 5B drop party not to tell you that you should be doing one, or to tell you that you should even be doing a drop party at all, but to show the vast difference between one dicing clan giving away 5B versus another taking 100M for their events.
Your post is full of lies, you claim that you are not doing it for profit, but you are, and you don't want to admit it because it makes your clan look horrible.
If you weren't doing it for profit you would just do it as follows.
1 through 100, everyone pick a number just as you have done. First prize = 50% of sales taken in. 2nd Place = 30% of sales taken in, and 3rd place = 20% of sales taken in. If all the numbers aren't taken, big deal. Roll the dice until you hit numbers that were taken. Throw some kind of a free in game event before hand to gain more publicity, like a train or something. Allow people to buy last minute tickets on any unfilled numbers..
The situation above allows for less then 100 tickets to be sold, but everything given back to the people.
Also, think to yourself what kind of publicity your dicing clan will receive if you end up buying out all of the remaining tickets, and only yourself and other people who are a part of your clan are the only winners? This will make your clan look horrible. Even though it isn't possible to "rig" the numbers, if you end up buying out the remaining tickets, you allow yourself to break one rule, which is the max number of tickets allowed to be purchased, and you put the odds heavily in your favor without as much risk as some average sythe user would have put as not only do you have chances of winning, but you automatically "win" 100M. You can buy 20 tickets and not lose anything yet have a free chance of winning.
You shouldn't want to put your dicing clan in this situation. If yourself or other high ups in your clan are the only winners, which with your set up is perfectly possible, it will make your clan look horrible. You shoulda just stayed out of it and not allowed your members to participate, because you are essentially gambling with your publicity on whether it will end up being good or bad.
Hopefully you actually read this and take it to heart, and think to yourself how messed up it will appear if the above scenario happens. You will drive away your business.
