Many times 2 digits return in pick 4....... but many times doubles hit and mess this system up. Doubles hit about HALF the time in Pick 4 ......unlike pick 3 where they only hit about 27% of the time.
So... with the doubles thing in mind. Here is a good Pick 4 System.
Go from the last drawn digits ..... Example 0123
Now.....just pick the 2 digits you think will return next draw. Say .....the 0 and 1 will return
Next ..... wheel all the digits that did not hit in the last draw as pairs . In this example wheel 0123 4,5,6,7,8,9
We will make pairs out of the remaining digits of 4,5,6,7,8,9, that did not hit last.
45 46 47 48 49
56 57 58 59 ++ 01 = 4501 4601 4701 4801 4901 5601 5701 5801 5901
67 68 69 6701 6801 6901
78 79 7801 7901
89 8901
Now put these pairs with the 2 digits you think will return ... the 0 and 1
If no double hits .....and you picked the right 2 returning digits you win.
(It's only 15 numbers to play ....and in Pick 4 that's nothing)
