玩双色球的过程中，无论把33个红色备选号码球怎样划分区间，总会时不时地有某个区间不出号（即所谓的断号或断档）。如果我们在选号时，能够把不出号的区间排除在我们选号范围之外，就会大大缩小选号的范围，增加中奖的机会。 -Loans play the process, regardless of the number 33 red balls what division options range from time to time there will always see a certain number range (the so-called off or断档).选号If we can not issue the interval excluded from the scope of our选号, it will greatly narrow the scope of选号to increase the chance of winning.
