The Last Digit Bias Tracker is a lotto strategy chart in Advantage Plus lottery software (Chart G) and the Lottery Master Guide book. The chart helps pick the three or four Last Digits of lotto numbers which are most likely to be drawn and shows the Last Digits which are less likely to be drawn as winners. The Last Digit Analysis chart shows the hottest and coldest ending numbers. Last Digit(s) most due would be included or excluded according to their strength in other charts. This chart works just as well for new Lotto games with very little history.
