In Excel I built a spreadsheet that only gives you all straight Pick 3 numbers that must include at least one number from the last three draws. This varies but will give you ~600 straight numbers. If any of the numbers repeat from the last drawing the number will be in this set. Obviously you have to reduce this set further. Waiting for Lottodds to have the capability to upload numbers so I can look at further reduction. Keep in mind this only hits around 60% of the time so any further reduction can not eliminate the winning number.
Just look at any Pick 3 history, anywhere, any state, you see a number from the previous in the new draw draw constantly, ~60% of the time.
Supposedly the above can be accomplished in Lottodds but I haven't figured out how to do it, also would be great it there was a double and triple eliminator instead of having to set up a complex reduction.
