I did on paper last 200 games, spent 2 to 3 Straight tickets per game , but I also knew which games to skip, so ended up "playing" about 80 games, so alltogether "bought" about 250 tickets. I did this: take existing combination, multiply by 7, if result has doubles in it, I will "play". Example: 6465. Then I devide this same initial combination by 7, get 2 numbers in a result, say, 72. Then I take 4 and 5 out of first answer ( second and last number), 45, and add 7 and 2 = 457, 452. Use calculator. :) If I got two numbers and then fruction, I use three numbers out of the result and make three tickets.
I skipped games where after multiplying combination by 7 result did not have doubles : 7398. They never produce match. I also skipped games that after multiplying produce only three numbers. There was a lot of results like those mentioned. For the first 150 games there was no luck, but then during last 50 games it hit twice. I "won" $1000. So, $1000 -$250 = $750 pure profit in a period of time that equals 200 games, so it's 100 days, or three months, but only about 80 games. It could be that trend continues in a future. I just got tired checking previous years. If interested, try it. I like that this system requires few tickets per game.
If someone is so daring a sto play 10 times more of the same tickets, then after spending $2500 they can win $10000.
