'Key and offset' system for Pick 3/4
Difficulty level: easy
Example:
Last draw was 1-2-3
second draw back 4-4-5
third draw back 7-6-6
Working backwards in time, the very last digit drawn was 3; next-to-last digit drawn was 2; next back was 1; next back was 5; next was 4; next was 6.
Note that repeat digits are ignored and they are listed in most-recent to least-recent sequence.
The sequence is: 3 - 2 - 1 - 5 - 4 - 6
The first 3 digits of the sequence ( 3 - 2 - 1 ) will be used as key digits. Every combo will have at least one of those digits.
The last three digits of our sequence ( 5 - 4 - 6 ) will be 'offset' by subtracting 1 from each digit.
5 4 6
-1 -1 -1
4 3 5
Combine 4, 3 and 5 into three pairs using the same sequence like so: *43, *45, *35
Now put each of your key numbers (3, 2, 1) in the first position followed by your pairs.
3-4-3 3-4-5 3-3-5
2-4-3 2-4-5 2-3-5
1-4-3 1-4-5 1-3-5

Play pick 4 using the same system. Instead of making pairs use all three offset digits for three combos. For more plays, just add more digits to your original sequence.
Using the above sequence as an example your pick 4 combinations would be
3-4-3-5
2-4-3-5
1-4-3-5
(side note: the other night I played pick 4 which I never do. Using this system I played the first combo generated - 1425 - and the result was 1424. I thought that was pretty cool.)

I like the combos it comes up with and oftentimes they are very close. See how it works for you in your drawings before wagering.
I keep midday and evening draws seperate but it can be played draw-to-draw as long as the most-recent to least-recent sequencing is used. I play them straight/box.
Have fun with it and good luck!
