The filter accepts tickets that have desired count of numbers that are adjacent to the numbers of the latest draw. A number is adjacent to some other number if it is one lower or one higher than the other number.
Optionally it is possible to adjust the distance of adjacent numbers using +/-1 to +/-5 check boxes. For example selecting option +/-4 means that a number will be adjacent to some other number if it is greater by 4 or lower by 4 than that other number.
Note: The filter compares the numbers of filtered tickets with the numbers of the latest draw within the past draws selected in filter window. So selecting for example Winning Numbers: All draws and Winning Numbers: 10 latest draws in Expert Lotto 6/49 Demo lottery has the same effect, the adjacent numbers will be compared to the very latest draw which is 2010/28 Sun 2nd.
The latest draw in Expert Lotto 6/49 Demo Lottery is:
2010/28, Sun 2nd, 23-29-36-42-44-47-[07]
Filtering with settings Winning Numbers: All draws, Adjacent numbers: +/-1, min: 2 max: 4 accepts for example ticket 1-2-3-4-22-24. The last two numbers of that ticket are adjacent to number 23 in the latest draw.
