Count of Similar Groups in Draw

This method does not look at which specific groups of similar numbers are selected, but counts the similar number groups to see how many distinct groups of numbers ending with the same digit appear in the draw
 
Lottery numbers can be divided into 10 groups, based on their last digit (ending digit):

Group 0: Numbers ending with 0 (10, 20, 30, …)

Group 1: Numbers ending with 1 (1, 11, 21, 31, …)

Group 2: Numbers ending with 2 (2, 12, 22, 32, …)

Group 3: Numbers ending with 3 (3, 13, 23, 33, …)

Group 4: Numbers ending with 4 (4, 14, 24, 34, …)

Group 5: Numbers ending with 5 (5, 15, 25, 35, …)

Group 6: Numbers ending with 6 (6, 16, 26, 36, …)

Group 7: Numbers ending with 7 (7, 17, 27, 37, …)

Group 8: Numbers ending with 8 (8, 18, 28, 38, …)

Group 9: Numbers ending with 9 (9, 19, 29, 39, …)

Each draw pulls numbers from a subset of these groups.

For example:

Draw = 1, 12, 3, 33, 44

Group 1 → (1)

Group 2 → (12)

Group 3 → (3, 33) - 2 numbers from group 3

Group 4 → (44)

→ 4 groups in total
 

or
 
Draw = 1, 12, 22, 33, 43

Group 1 → (1)

Group 2 → (12, 22) - 2 numbers from group 2

Group 3 → (33, 43) - 2 numbers from group 3

→ 3 groups in total

 
So, this analysis methods just counts the occurrences of groups

Tracking the count of similar number groups helps reveal whether the numbers in a draw are spread widely across many digit groups or concentrated within just a few.

A higher count, for example when 4 to 5 different digit groups appear in a single draw, indicates a higher spread of numbers. This suggests that the draw covered a broad range of endings.

By monitoring these counts over time, you can compare each new draw against historical patterns. This allows you to filter or select tickets that avoid being too narrow or too wide compared to what typically occurs, helping you align closer to realistic distribution behavior.
 
In practice, draws almost never come from just 1 or 2 groups. Instead, they are usually formed from a larger spread of groups, showing that multiple ending digits are almost always represented.
 
So, choosing numbers like 1, 11, 21, 33, 43 could be a statistical mistake as the numbers coming from  2 groups only are rarely drawn.

This filter can be used to filter out lottery numbers, wheel system combinations, or generated tickets.
You can filter those numbers by the Count of Similar Groups in draw to eliminate unnecessary numbers which are composed of groups combinations  that are rarely drawn

On the Filters page select the Add Filter tab, choose Groups of Similar Numbers from the list on the left side of page.
Select Count of Similar Groups in Draw particular filter from the list on the right side of page.

Click the Add Filter button located on the toolbar. Selected filter will be added to your Game Filters list.
If you want to add more than one filter, select more filters using CTRL+A keys to select them all or hold CTRL key and select filters with mouse
 
For more detailed information about filters page please see Filters Interface topic
 

After adding the filter, you can go to the Game Filters page in the same Filters window to edit the filter properties.

The added filter will be located under the Count of Similar Groups in Draw group of all filters, with its value in the Property cell set to 1 as
 
Use

If selected, the filter will be used to apply filtering.
 

Action

Sets the filter action applied by the filter to determine the final outcome when the count of distinct end-digit groups meets the condition.

You can choose to accept or reject ticket combinations.

Accept action:

Only wheel system combinations or generated ticket numbers where the count of distinct groups satisfies the condition will be accepted.

Reject action:

Only wheel system combinations or generated ticket numbers where the count of distinct groups satisfies the condition will be rejected.

 
Property

Not used, shows filter name only

 
Number Main Type

Not used with this filter

Number Subtype

Not used with this filter

 
Value

Sets the condition value for the filter to be satisfied.

You can set here how many groups you want to analyze.

Range

Displays or sets the filter's condition range value, used only when the filter's condition is set to a Range of Values.

You can set here the range how many groups you want to analyze, for example 4 5, will accept or reject numbers that are drawn from 4 or 5 groups

Condition

Filter conditions you can apply to meet the filter Value option criteria .

You can select a filter condition from drop-down list combo box one of the following conditions:

Any Number

Not used with this filter as numbers always are from some groups

Equals Filter Value

When you choose Reject action then:

Tickets or wheel system combinations where the count of groups equals the Value cell will be rejected.

When you choose Accept action then:

Tickets or wheel system combinations will include only selections where the  count of groups equals the Value cell.

Higher than Filter Value

When you choose Reject action then:

Tickets or wheel system combinations where the count of groups is greater than the Value cell will be rejected.

When you choose Accept action then:

Tickets or wheel system combinations will include only selections where the count of groups is greater than the Value cell.

Lower than Filter Value

When you choose Reject action then:

Tickets or wheel system combinations where the count of groups is less than the Value cell will be rejected.

When you choose Accept action then:

Tickets or wheel system combinations will include only selections where the count of groups is less than the Value cell.

Range of Values

When you choose Reject action then:

Tickets or wheel system combinations where the count of groups falls within the Range cell will be rejected.

When you choose Accept action then:

Tickets or wheel system combinations will include only selections where the count of groups falls within the Range cell.
 

Here is the example of setting up filter to filter wheel system or numbers when generating tickets:
For example in a game 6/49 and for flexible and rather fail safe filtering please do as following
Set the Action property to Reject
Set the Number Main Type and Number Subtype to All

Under Filter Condition Options > Value set the value to
Under Filter Condition Options > Condition choose More Than Filter Value condition

Select from the Visual Analyser menu select:

Grouped Numbers > Groups of Similar Numbers > Count of Similar Groups in Draw
The result of analysis is shown on a Visual Analyser's screen

The first diagram shown at the top of screen illustrates the general occurrence of Count of Similar Groups in Draw numbers.
 

The diagram will show a point in the row corresponding to the count of groups
The upcoming diagrams will examine numbers drawn as the main type and their combinations with other types.
Please note that the diagram will never display a point in row 0 since the numbers always belong to specific groups.

In the sample diagram above, you can also observe that row 1 lacks points indicating a draw from a single group only. This means that, in a game, numbers from only one group are never drawn.
