There are 2 main type of wheeler filter in this program. The system filter or user define filter.
Below are filters that belong to the system itself. You cannot change or modify these filters.
This filter conditions are predefine by the system according to the system you are generating. You only need to select the conditions listed in the pop-up window. Example below is a system 6 Odd/Even filter box. You will need to click on the tick box to select it. You can select multiple conditions according to your preference.

These filter conditions are base on the grouping defined in the Statistic Grouping function. Any groups that you defined in that function can be use for filtering. The different between this filter with the System filter is it allow you to expand your filter according to your requirement. Beside selecting the condition, you can also specify the size of the condition. To explain more about the usage of the size, I need to use an example. Below is an example of Super 5 Group.

To include all the conditions, you can click the top row tick or you can click each of them individually. Noticed that the "Size" can vary from 1 onward, depending on the system you are generating. "Size" means the maximum number of "Numbers" from this group to be allow per generated ticket. The above example for group 28-36, I have set the size to 1. This indicated that only 1 of the "28 to 36" is allow in a ticket. This can be true only if your selection numbers consist of these numbers.
The rule of this filter is that when adding up the condition size, it must be more than or equal to the system size been generated.
The most common error that can happen is shown below,

If you only select 1 condition as shown above, the total size is 3. If you are generating system size 6, then you will get no ticket generated. But on another hand, if you specify the condition size as 3 and 4 as shown below, then you are actually specifying 3/3 or 2/4 as High/Low group.

There are unlimited extension that you can create with this type of filter condition.
You can edit or remove a filter from the selected list by clicking the filter as shown below.
