Your guess can contain one number higher than 15, but it's better to stick with the numbers 1-15. Why? Nine out of ten delta numbers will be 15 or less. This means that at least half the time, there will be no delta number greater than 15 in a given six-number-pick. As there are more possible numbers greater than 15 than there are numbers less than 15, its just better strategy to focus your guesses on those cases where the odds are in your favor.
Choose a lucky number and stick with it. Some people choose a number sequence that they consider lucky and play it over and over again until it comes up a winner -- if it ever does. For instance, if you’re favorite number sequence is your favorite number, combined with your birthday and your spouse’s lucky number and birthday (3-6-11-9-10-31), then you would play this number religiously every time you play the lottery. Then, you wait for your number to come up a winner. This could be considered making your own luck.

In 2008, there were 1.03 deaths per 100 million vehicle miles traveled in the United States. Based on these odds, a lottery player living a single mile from a store selling lottery tickets is four times more likely to die in a car accident driving to the store than to win the Powerball jackpot. Winning doesn’t seem too likely now, does it? Keep those odds in mind the next time you drive to the store to buy lottery tickets!

Though playing the lottery is a game of chance, that doesn’t mean you can’t have a method for choosing your lottery numbers.
