Scratch off tickets can be addicting?

I never cared for scratch off tickets for years and I started playing 2 weeks ago. Decided to buy 10 1 dollar lotto tickets at a cash station and off the 7-11-21 tickets I won 75 dollars and was so happy. It was off my 2nd 1 dollar scratch off ticket I purchased. So lately I spent about 300 dollars in 1 and 2 dollar lotto tickets and only one other big time and that was 10 dollars X3 which turned out to be 30 dollars (at first didnt know it) I am trying to think which lotto tickets I can hit big on. I am in Chicago illinois. Please let me know and most you won?
