Hi cohenj,
All 49 numbers will *usually* show up within 25 to 30 games. Some lotto analysts use this size of a database range for this reason. The average frequency of hits for all numbers range roughly between 7 to 9 games. But dead numbers can certainly exceed this general average. Many times numbers can go to sleep and not appear for 50 plus draws. Number 28 is the biggest culprit for disapearing for long times. It has played dead for 37 and 51 draws and holds the record for missing in action an incredible 72 times in a row. This is why the "cold therefore due" theory of number selection does not work. When a number takes a vacation it could be a long one.
Good Luck in tonight's BIG $ draw.
