Powerball - Last White = 59 spots, Red Ball = 39 spots
Megamillions - Last White = 56, Yellow Ball = 46 spots
Pick 3 = Last 2 = 100 spots (00=100)
No clue how you are going to do 70. Put 70 numbers in a hat and draw one with a lot of AZ members near you? Live stream it?
*edit* Doesn't Bingo use 70 balls? You could get a bingo machine and live stream the drawing! Ok, I need to get back to work, I'm just being dumb now, heh.
