Howdy, Stalyn, there can be problems knowing what pairs for which game and when. I do graph tracking and get a fair idea of what andwhich pairs should hit. If you are in the States, you will have one or two games in your area, if somewhere else, you will still have to have a good printout of at least a couple months worth of past winners to get an thought or two about how the pairing system works. Some places have a single game, seven days per week and one day on a Saturday. The Canadian WCLC Pick 3 works seven day per week only but have extra or bonus numbers that can cause some degree of difficulty.
You must have some way to track numbers; a way to plot how the digits are running and possibly a way to sort of "predict" their next movements.
This is the bare bones of finding those pesky pairs!
