Manage Number Groups
Number
Groups Manager window opens from menu Tools - Number Groups. In this
window you can see a list of all number groups defined for the current
lottery. Use the buttons at the top of the window:
Add - start Number Groups Wizard to create a new number group.
Hot/Cold - create new number group based on hot/cold/warm numbers, see below.
Import - create new number from a text file, see below. This option is not available for Pick-N lotteries.
Duplicate - create a copy of selected number group. Changes made to the copied
number group do not affect the original number group it was copied from.
Customize - opens selected number group in Number Groups Wizard window to modify number group settings.
Remove - permanently deletes the selected number group. 
- moves selected number group up or down in the list. The order of number groups affects the order of columns in Winning Numbers Properties and Package Properties windows. So reordering the number groups allows to see some number groups stats side by side in those windows.
Filter - opens Package filter window for the selected number group. The button is enabled only when there are any tickets in the Package.
Hot/Cold Number Groups
It is possible to create number groups consisting of hot, cold and warm numbers. First select past draws to calculate hot/cold numbers from. Then choose how many of those draws should be used to find hot numbers. Next you need to specify the minimum occurrence of hot numbers and the minimum occurrence of warm numbers. The actual distribution of pool numbers into hot/cold and warm categories is given in the table at the bottom of the window.
For example ten latest draws in Expert Lotto 6/49 demo lottery are:

Let's use the following settings to create Hot/Cold/Warm groups:
- Draws: 10 latest draws
- Draw limit for hot numbers: 4
- Min occurrence of hot numbers before draw limit: 2 After draw limit: 1
- Min occurrence of warm numbers: 2
It means the hot/cold numbers will be calculated from the occurrences of pool numbers in the latest 10 draws (see the table above). The draw limit field divides the table into two parts. The latest 4 draws have orange background, the previous six draws have blue background.
A number is hot if it hit at least two times in the orange section (before draw limit) and at least once in the blue section (after draw limit). In this example there are only two such numbers - 23 and 29.
If we change the settings to Min occurrence of hot numbers before draw limit: 2 After draw limit: 0 then there will be five hot numbers - 13, 16, 23, 29, 42. They are numbers that hit at least twice in the orange section.
A number is warm if it isn't hot and if it hit at least two times in the selected ten past draws. There are 16 such numbers, for example 2, 6, 8, 11 etc.
All other numbers are cold - they hit at most once in the latest ten draws. There are 31 cold numbers in this example - 1, 3, 4, 5, 7, 9 etc.
Note: Number groups created this way are static - so when you add fresh winning numbers into your database you have to create new Hot/Cold numbers groups to take the latest numbers into account.
Importing Number Groups From File
Clicking Import button in Manager's window toolbar opens standard Open file window where you can browse a text file that will be converted into a new set of discrete number groups. The file being imported is expected in the following format:
- each line represents a single group of numbers
- values on each line must be separated with comma (,), semicolon (;), dash (-) or space or tabulator char
- the first value in each line will be used as number group name
- values that are not numbers or duplicate numbers or numbers out of pool range are ignored
- lines starting with # character are ignored and can be used for comments
After successful file import it is possible to remove or edit the original imported file - the numbers groups created by the import action will remain unchaged.
