you have asked a pronounced sticky question that, it seems, only salesmen will answer concerning pick3 and pick 4 games. Everybody in that work classification want you to buy into their pet wheels, programs and goobly-glok. While it's great for their economy, most of it is not good for your$.
I have been down this road before and were I you, I would believe in the computer and programs that are totally free and you own. Your brain my friend. Ask yourself this question and see if I'm wrong or right, "how many times has any program won in one month and shown guarantees as a backup if it doesn't win?" This answer is rather easy, wouldn't you say? How much money that you have spent or that people that you know have spent and have only made a few paltry bucks verses the hype (advertizements) that would give you a pie in the sky according to the beautifully packaged and colored discription of what those programs will do? I admit to being a proponent of what you were given at birth and to use it as you will. I am not against the other fellow making a living but you must admit that there have been times that you have noted something that someone else came up with and said to yourself, I could have done that or I knew this a long time ago." That other fellow may "take " your hard earned money, but he will earn mine!
What makes a program work? Ablibing your own thoughts around what the program has generically given you. You do not have to be a programmer to know that the basic ideas for that program came from minds just like yours and mine. Why not really turn yours on and see what might happen...the results can be very supprising.
