In FL Pick 3 lottery I used to take numbers of last game, and subtract from them 1,4,7 in different configurations, 6 additions. 147, 174, 471, 417, 741, 714. The results of that subtraction, say, had two combination with 2 identical numbers. I'd use this combination to calculate tickets. If results had two numbers with identical pair, I"d subtract them , second from first, in a simplified manner, like for lottery, and then use that result to calculate tickets. Example 927 - 471 = 556  Say, I am left to work with 633. I'd create splits, 6a3, 3a6, 3a3, where "a" means every number has to go inside, making 10 tickets, altogether 30 Straight tickets with a goal to win $500.  Then again, what if numbers fall to the side: 63a, 36a, 33a and a36, a63, a33. Now I end up with 90 Straight tickets. I am not such a player though to spend so much at once. But, as I calculated on paper, it worked in a way that may be for 3 games I spend 90 tickets each, and only third one brings $500. It kept going until it stopped working, because obviously the trend got worn out, it weathered away. At such time one needs to come up with new trend and they seem to be usually short lasting.
