I use to do extremly well in scatch of tickets when i worked at a gas station just out of highschool, but ya have to have money to waste in order to get slightly ahead. I watched people dump 400$ in a half hour to win 120$ and get excited about the 120$ - even told the one lady ya know you could come in here give me 50$ keep 50$ for yourself and walk away much further ahead. Anyways i was up about 1K$ because i would watch the ticket cards and in PA, any time the big winners of the tickets are sold they pull the remaining cards because of advertisement issues, i know some states sell every single one.
Well because of me working there i could see what in a new ream of cards was hitting and what wasnt, the average 20$ ticket has a few 50$ winners a few 100$ winners and some times a 250$ winner, in every ream, always at least 2 50's and 1 100, always --- so i couldn't play on the clock but after my shifts i could and i would just get a better than average educated guess on what was hitting hot and what hasn't hit hot yet. Tried that shit once i quit working there and went from upp 1000$ to only up $600 - needless to say i havent played any since. Highest ticket i sold was a $5000 winner at xmas, which i was going to play before my shift started but was too lazy to walk to the ATM, and next guy up bingo! This was all approx 8-10 years ago.
