They're not televising the drawings, so far can't tell.
Results are on the in-state only 800 number.
See the thread in News, Illinois New game.

This thread also, in Discussions.

I'm going to mention this blog article of yours in the News thread, people are asking about the drawings, pre-test, etc....

OK, sounds good.

Good Day,

Thank you for your question. The My3 is drawn using the balls on a machine.

But there's something peculiar about the way this game is being presented.

Go to the Illinois Lottery web site, http://www.illinoislottery.com/en-us/home.html, and look for the link to the My3 game.

There you'll see a link to 'Watch the Draw', http://www.illinoislottery.com/en-us/my3.html#draw=M or http://www.illinoislottery.com/en-us/my3.html#draw=E .

On that page is a section at the top that shows the numbers for that day.

Where are the Humans? Where are the same manner machines?

If this is the same manner as the others, then I'd have to conclude based on this, they are computerized or at the very least the other are going to be.
