I've always been told that the tickets with the lower numbers (100 or less) have a greater chance of winning, this for any scratch off ticket. Usually in the lower right corner there's a small gray box with a number in it like "046". These low numbers seem to be winners more. I have a few relatives who are addicted to these things and constantly win.
There are no secrets to picking a winning Scratch of Pennsylvania Lottery Ticket. The reason why so many scratch players lose is due to lacking strategy. This in turn leads to lack of ways of pinpointing your way to figure the correct ticket to buy.
