The filter accepts tickets that have the same pattern of distribution of numbers into selected number groups as any of the selected past winning numbers draws.

When filter settings are Winning Numbers: 3 latest draws, Number Groups: Default then filter accepts for example ticket 1-11-12-13-21-31. The distribution of its numbers into the default number groups is 1-3-1-1-0 which does match one of the selected draws (2010/28 Wed 2nd). The filter also accepts for example ticket 23-26-37-42-44-46. Its number groups distribution is 0-0-2-1-3 which matches selected draw 2010/28 Sun 2nd. Another accepted ticket is for example 6-13-14-19-41-42. It has the same numbers as one of the selected draws (2010/28 Sun 1st) so it has also the same number groups distribution 1-3-0-0-2.
Filter rejects for example ticket 1-2-3-4-5-6 because its number groups distribution is 6-0-0-0-0-0 which does not match any of the selected past draws.
