As you might know, due to the U.S. Government most people here don't play and or are unable to play the 'Daily" U.S. games online at places such as the one were you play at, not in the "Normal" way anyway, Including myself.
So then "We" can only play with our own state's lottery at about $500 payout for a straight pick 3 win and $80 per boxed (Any Order) win at $1 each.
But going by what you said, even at the much lower payouts there might still be some kind of a profit.
So maybe instead we should assume the lower payouts given by the state lotteries as maybe most people here will have to go by those.
A long time ago on the pick 3 forum I made a very nice straight prediction, here is the link to the thread where it is at:
I think that it might have been my very first use of that filters program that I used to make that prediction with.

Good luck!
