Using the Illinois 6/52 state lottery for example, there will be 6 numbers drawn for every draw. Therefore, over 200 drawings, 1200 numbers are drawn. Each lottery digit from 1 to 52 should be evenly HIT 23.07 times (1200/52). However, we all know this seldom happen in reality. While most numbers are hit 23 times, there are some numbers that are hit less than 15 times while others appear more frequently than 30 times!
According to the law of large numbers, the average HIT rate for each lottery number should hold but over a recent period of consecutive draws, there will be biases among the numbers being HIT. That means if the results are computed over 1,000,000 6 number lottery draws, then each number is more likely to appear (1000000/52) around 19230 or 19231 times with a very narrow deviation.
This is actually the very loophole exploited by real lottery software based on statistical methods. By identifying the HOT numbers over 100 recent draws, you stand a higher chance of winning the lotto jackpot using combinations of HOT numbers. Some lottery softwares choose to use mean reversion techniques, meaning that numbers that have not been HIT in a draw for a long time are more likely to appear. Depending on the state lottery systems, different types of lottery software are more likely to predict winning numbers.
Many people are not aware of this fact - scientists have yet to invent the ideal, perfect random number generator. That is why there are always some slight skew in the numbers that are HIT in lottery draws. If you stick to manually picking your numbers to buy, you are not getting any advantage over the system. On the other hand, full time lottery players use advanced lotto software to help them analyze trends in the results and pick HOT numbers that are more likely to win.
