This system (for Jackpot Games) is VERY simple.
You simply use previous draw(s) for any jackpot game, and Add a constant Shift number.
ie. if previous draw was like 1,2,3,4,5, a shift of 2 would give you 3,4,5,6,7.
That's it. The idea here is that we choose new numbers based on the same Deltas (The differences between our chosen numbers is the same as differences between previous draw data).
The image below shows an example for Powerball using Shift constant of 13.
