Back in college I did a test to see how many winning tickets in 50 consecutive $1 tickets. I bought 50 tickets at $1 a piece, basically got 1/2 of the roll. Went home, scratched them all up and got like $10 profit. Pretty bad actually. Later find out that $1 scratchers are the worse to play, sure those that are lucky won the jackpot amount, but usually no more than $1,000.
If you're going to play scratchers go for $5 or more per ticket. Give yourself a chance to win, even at low tier prize it's worth while.
