One more method of choosing lottery number is randomizing the selection. You do not have to think much and just choose any number of your choice. And anyhow lottery is a game of choosing random numbers. If you are allowed to choose any number of lottery numbers then see that you do not choose too many numbers. Because chance of winning is inversely proportional to the number of numbers you choose. Now, you may also use special numbers for picking the numbers. These special numbers can be anything, like your age, your daughter's/son's age, your mobile number, your house number, your husband's/wife's age, etc.
Select numbers that are drawn frequently. If you notice that a few numbers stand out for being drawn significantly more often than the others, consider including them in your pick. Be aware, though, that several other people will be trying this tactic; if you win with frequently picked numbers, you might be at a greater risk of having to share the prize with other winners.
