There is definitely a pattern to the winning tickets in pa lotto scratchers. For example, one of the $1 tickets yields 3-4 winners in every 10. The problem is the winners are usually free ticket, $1 and $5 with the latter being more rare. According to the articles I've read, the more expensive scratchers are the big winners. I once won $25 with one of these, but you've got to have a couple hundred dollars to invest in the big tickets and I don't have that.
