The Number Groups Bias Tracker is a lotto strategy chart in Advantage Gold lottery software (Option E) and the Lottery Master Guide book. The chart tells which number group(s) can be eliminated from your field of play and which number group(s) should be more heavily played in the next drawing. If you want to know if you should play more numbers in the teens, twenties, etc, use this chart to see past action in your lotto game.
