The
filter accepts tickets that have the desired count of *consecutive first or last digits*. Each pool number breaks down into two
digits. The *first digit *is the leading digit of the number, the *last
digit *is the second digit of the number. For example the first digit of number
23 is 2, the last digit of that number is 3. The first digit of number
9 is 0, the last digit of that number is 9.

Digits are consecutive if each digit is one higher than the
preceding digit. For example digits *5,6,7* are consecutive, digits *5,7,9* aren't consecutive.

**Important:** Last digit sequences like *15-16-17-18-20-23 *are always
interpreted as four consecutive digits (5,6,7,8), such combinations are
never treated as two pairs of consecutive digits or one triplet of
consecutive digits. The same applies to first digits.

- When filter settings are
*The count of 2 consecutive last digits is 1 to 1*then: - 01-02-05-08-11-15 - filter accepts this ticket because it contains one instance of two consecutive last digits
*1-2*. - 01-02-05-08-09-15 - filter rejects this ticket because it contains two instances of two consecutive last digits:
*1-2*and*8-9*. - 01-02-03-05-09-11 - filter rejects this ticket because it contains one instance of three consecutive last digits:
*1-2-3.* - When filter settings are
*The count of 2 consecutive last digits is 1 to 2*then: - 01-02-05-08-09-15 - filter accepts this ticket because it contains two instances of two consecutive last digits:
*1-2*and*8-9*. - 01-02-05-08-11-15 - filter accepts this ticket because it contains one instance of two consecutive last digits
*1-2*. - 01-02-03-04-09-11 - filter rejects this ticket because it contains one instance of four consecutive last digits:
*1-2-3-4*. - 11-12-25-26-38-39 - filter rejects this ticket because it contains three instances of two consecutive last digits:
*1-2*,*5-6*and*8-9*. - When filter settings are
*The count of 3 consecutive last digits is 1 to 1*then: - 01-02-03-09-10-15 - filter accepts this ticket because it contains one instance of three consecutive last digits:
