When I look at the list of winning combinations of Pick 3 FL, I use a ruler, line it with upcoming whatever combination, I do not know yet,  with that of another column for the last game. I'd use fourth, third and second column winning numbers to make pairs, 12 per each 3 numbers. Within 50 games every column can deliver from 2 up to seven matches, so pairs match and I a win $50 per match. The trick is to guess when such match will come up. 

If one plays 12 tickets every game, it is $600 per 50 games, too much to spend, because $50 is not such a big win or wins, it won't cover expenses.
