Successive Numbers Filter

Menu: Filters  Successive Numbers

The filter allows to remove/leave in the package tickets with pair(s), triplet(s) and quad(s) of successive numbers.

After analyzing the winning numbers database you will probably find out that almost half of the draws contain one pair of successive numbers. On the other hand tickets with five or more successive numbers are very rare. Therefore you may decide to remove such tickets from your package.

Expert Lotto offers the Successive Numbers filter to do so.

This simple filter allows to remove or leave tickets that contain the given count of successive numbers (pairs, triplets, quads etc). The maximum count of successive numbers depends on the count of numbers in the ticket. There must be at least one quad of successive numbers. If the ticket can contain more than one quad (e.g. lotteries where you can bet 10 numbers in one ticket) it will pass filter's condition the same way as the tickets with only one quad.

To demonstrate how this filter works select the Expert Lotto Keno lottery and generate 100 tickets with 10 numbers in each. Then use the Successive Numbers filter to leave only tickets with one triplet of successive numbers. Now apply the filter again to filter the remaining tickets to leave only tickets with 1, 2 (or 3) pairs of successive numbers. Each triplet will be now considered as a pair only. That's why when filtering tickets with two pairs of successive numbers the resulting tickets will include also tickets with one triplet and another pair of successive numbers.

The filter leaves/removes tickets containing at least the required count of two- three- or four successive numbers. If you define requirement to remove tickets containing "1" couple also tickets containing 2 or 3 couples and 1 or 3 triplets or 1 quad will be removed.

Four successive numbers are considered as two pairs of successive numbers (it's in fact three pairs of successive numbers) and also as one triplet (it's in fact two triplets of successive numbers). Therefore a ticket will not be removed when filtering out tickets with only one pair. The ticket will remain in the package also when filtering out tickets with three pairs of successive numbers.

Example [Expert Lotto 6/49]: Enter into the package the following tickets "1,2,3,4,5,6" and "1,2,3,5,6,7" and "1,2,3,6,7,8" and "1,2,3,7,8,9" and "4,5,9,10,11,49". Ticket 1,2,3,4,5,6 matches the condition for two triplets of successive numbers in a ticket and also the condition for one triplet of successive numbers. At the same time the ticket matches condition for three pairs, two pairs and one pair of successive numbers. A ticket with one pair and one triplet of successive numbers (e.g.. 4,5, 9,10,11,49) will match filter's condition for one triplet of successive numbers and also for two pairs of successive numbers.

So when you want to keep tickets with one and only one pair of successive numbers you must first select tickets with at least one pair of successive numbers and then filter out tickets with two and three pairs of successive numbers.

The filter does not take into account dummy numbers.
