This filter accepts tickets that have low or high numbers at specified ticket positions. Number is low when it is in the lower half of number pool, number is high when it is in the upper half of number pool.
For example in a x/40 lottery, numbers 1 to 20 are low, numbers 21 to 40 are high numbers. In a x/49 lottery, numbers 1 to 24 are low, numbers 25 to 49 are high.
To use the filter, first tick the ticket position you want to filter and then choose whether a ticket number at selected position must be low or high. Option At least X to Y positions must pass specifies how many positional conditions must be met to accept a given ticket.
Filtering with settings Position 1: Low, Position 6: High, At least 1 to 2 positions must pass accepts tickets like 1-30-35-40-45-49 because the first and the last ticket numbers are low and high respectively. Filter also accepts ticket e.g. 1-2-3-4-5-6 because the first number is low and the last number is also low, so at least one filter condition is met as required.
There is no ticket to pass filter settings Position 1: High, Position 6: Low, At least 2 to 2 positions must pass. Because ticket numbers are sorted in ascending order in the Expert Lotto 6/49 demo lottery so there can never be a ticket with the first number higher than the last ticket number.
