Here are a few free number selection tips from Gail Howard’s lotto book, Lottery Master Guide, which have been customized for this specific game: Philippines Lotto 6/42. (Additional best tools for this game.)
Lottery numbers are randomly drawn. But randomly drawn numbers form patterns that can be tracked and used to our advantage. Having carefully analyzed all the drawing results of more than 160 different Lotto games worldwide, with histories going back as far as 1955, Gail Howard have verified the following incredibly simple rule:

That which is MOST POSSIBLE happens MOST OFTEN.
That which is LEAST POSSIBLE happens LEAST OFTEN.

The key to Gail Howard’s successful number selection methods is playing the probabilities. If you play a pattern that occurs only five percent of the time, you can expect that pattern to lose 95 percent of the time, giving you no chance to win 95 percent of the time. So, don’t buck the probabilities.
