Following is the summary of the oddeven ratio statistics. Notice that a lotto combination is generally a mix of 3 odd numbers and 3 even numbers, capturing 35% of the total draws. If you want to capture a higher rate, consider also the 2:4 and 4:2 oddtoeven ratios. Overall, you capture the 78% favorable ratios with a hit index of 1.3, which means recurring, on average, every 1.3 draws.
The 5:1 and 1:5 oddeven ratios are worth trying if you want to capture an even higher probability. You just have to consider the hit index of 10 to 11 draws. To be exact, the ratios 5:1 and 1:5 combined has the tendency to recur again after 1 to 3 draws; other than that, it takes 4 to 23 draws.
On the other hand, the ratios 2:4 and 4:2 combined, with a hit index of 2.3, are sure to recur within the next 5 draws; while the ratio 3:3 is sure to recur within the next 3 to 4 draws.

Eliminating The Lower Probability
We already know that there are more than
28 million combinations that can be made from Lotto 6/55. But, based
on statistics, not all of them are good winning combinations. Based
on the data above, you can eliminate the 3% of the combinations.
These are the allodd (6 odd numbers)
and alleven (6 even numbers) numbers.
If you want to reduce more your choices of combinations, you can
disregard both 1:5 and 5:1 oddeven combinations. With that you
still have 78% probability chances. To simplify the way you combine
numbers, you can opt to focus on 3:3, 2:4, 4:2 oddeven ratios.
How many combinations to play?
To ensure that you target the highly
probable combinations, play 9 combinations as follows: three 3:3, two
2:4, two 4:2, and one each for 1: 5 and 5:1 oddeven ratios. If you
are budget constrained, play 5 combinations where 2 combos are 3:3
oddeven and one each for 2:4, 4:2, and 5:1 or 1:5.
What's the ideal order of the odd and even numbers?
Perhaps you want to find out which number
should be odd or even. The answer is any number in any order. Take a
look at the data that follows.
Notice that the odd and even numbers are fairly distributed. That's less headache for you
because you need not concern yourself about where should be odd or
even.
