you would, but not really enough to make up for it all.
Someone tried this as part of a large group with a different lottery years ago... there was a show on it. They didn't win the jackpot,though.
The thing is powerball has recently changed it's rules to make this larger jackpots possible by increasing the number of balls played. Which makes any attempt to game the system that much more difficult.
And finally, it's a lottery. It's set up so the 'house' always makes money no matter what.
I have friends who play the slots, they are always telling me about the jackpots they win.
I just don't know how the casinos are staying in business!
