### Odd-Even Combination

Odd numbers are those which end in 1, 3, 5, 7 and 9 while even numbers are those which end in 0, 2, 4, 6 and 8. You are more likely to win if your odd-even number combination is either 2-4, 3-3 or 4-2. More than 70% of the winning combinations in the Philippine Lotto 6/42 in the past two years are in this category with the 3-3 (three odd numbers and three even numbers) combination leading with more than 30% of the draws.

### Sum of Numbers

You’re chances of winning are higher if the sum of your number combination is within the middle range of all possible sums. To compute this, just add the first six numbers and the last six numbers of the lotto balls and divide by two. For the Philippine Lotto 6/42, it’s 1 + 2 + 3 + 4 + 5 + 6 + 37 + 38 + 39 + 40 + 41 + 42, which is equal to 129. Add and subtract at the most 30 to that and you will have the best range for your sum. In 2006 and 2007, the sum of more than 70% of the winning draw results in the Philippine Lotto 6/42 is between 99-159.

### Low-High Combination

Divide the highest ball number by two and you have the border for your low numbers and high numbers. For the Philippine Lotto 6/42, it’s 42 divided by two or 21. This means that the numbers from 1 through 21 are low numbers while the upper range of 22 through 42 are the high numbers. Just like the odd-even combination, probability shows that it is more likely that the low-high combination of the winning results are either 2-4, 3-3 or 4-2. Again, more than 70% of the results from the past two years follow this pattern with the 3-3 (three low numbers and three high numbers) attribute showing in more than 25% of the winning combinations.

These three are the major patterns which you should always consider.

Other factors worth mentioning are as follows:

### Consecutive Numbers

It is unlikely that the winning lotto draw result will have four or more consecutive numbers.

### Number Group

It is unlikely that the winning lotto result will have five numbers which belong to the same number group (five single-digits, five teens or five 20′s and so on).

### Last Digits

It is unlikely that the winning lotto result will have four numbers which have the same last digits.

These six rules are basically your best tools in evaluating if your number combination has a good chance of winning. Please remember that these are mere guidelines and does not guarantee that you will win. Mathematically speaking, the pattern of 1-2-3-4-5-6 has exactly the same chance of winning as any other random combination. So if your favorite numbers, your birthday, the ages of your family members or your wedding anniversary does not fall into these suggested patterns, don’t fret, you can still bet on that. In the final analysis, even if you don’t win, be happy with the fact that your money will be going to charity and will be used to help other people in need.
