LotSoftPro comes with a very extended Wheeling Engine which makes creating numbers using filterpatterns extremely easy.

The Wheeling Engine can be used with the following Filterpatterns:

• - Keydigits: by selecting keydigits the engine will only create numbers that have at least one of these digits.
• - Singles, doubles, double-doubles, triples, quads: select any of these options to exclude the creations of numbers that fit the selection
• - Consecutives: option to select if the numbers should have consecutive digits or not
• - HighLow (Low: 0, 1, 2, 3, 4 - High: 5, 6, 7, 8, 9)
• - OddEven (Odd: 1, 3, 5, 7, 9 - Even: 0, 2, 4, 6, 8)
• - InOut (IN: 3, 4, 5, 6, 7 - OUT: 0, 1, 2, 8, 9)
• - OpenClosedStraight
