Sequential 10-Block

This method divides the full range of lottery numbers into equal blocks of 10, such as 1–10, 11–20, 21–30, and so on.
These 10-number segments are called Sequential 10-Block Numbers and can reveal how numbers tend to group across past draws.

Description

In most lottery games (e.g., 1–49 or 1–59), the number pool can be broken into consecutive 10-number blocks:

Block 1: 1–10

Block 2: 11–20

Block 3: 21–30

Block 4: 31–40

Block 5: 41–50 ...and so on.

In picture below you may see circled in green color example of block 1.

Circled in yellow color is block 2, in red color block 3 ... and so on.

In majority of game lottery drawings, and in almost every game, there is an unequal distribution of numbers in certain blocks of numbers.

You can check out how the numbers are drawn using Visual Analyser and its Grouped Numbers > Sequentail 10 numbers Block sections.
 

Here is the example of possible not so good numbers choosing:
 

 
Most of numbers shown as circled in the ticket above are in the block of numbers from 1 to 10.
 
Analyzing which blocks are frequently or rarely hit in past drawings helps reveal clustering and gaps across the number field. For example, a draw might have 3 numbers from Block 2 and none from Block 4.

Sequential 10-Blocks are especially helpful in visualizing distribution. Balanced combinations often include numbers spread across 2 to 4 different blocks. Too many numbers from the same block may indicate a risky pattern, as such groupings are rare.

When creating tickets, consider selecting numbers that span at least two separate blocks, preferably from blocks that have appeared recently or are overdue. This improves coverage and reduces the chance of overly concentrated combinations.

Draws that contain 4 or more numbers from a single 10-block are uncommon. Also sometime rare are draws where all blocks are touched (e.g., one number from each of five different blocks). Most draws tend to involve 3–4 blocks with uneven distribution.
 

This filter can be used to filter out lottery numbers, wheel system combinations, or generated tickets.
You can filter those numbers by Sequential 10-Block to diverse numbers choosing across the game layout ticket
You can reject numbers from some blocks or accept from choose blocks

On the Filters page select the Add Filter tab, choose Sequential 10-Block main filters from the list on the left side of page.
Select Block 1-10 or other 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 Sequential 10-Block 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 that determines what happens when the block condition is met. Choose your option from the Action column drop-down:

Accept

Generated tickets will include some numbers from the block

The wheel system accepts only combinations that have some numbers from the defined block

Reject
Generated tickets exclude any numbers from the defined block

The wheel system rejects combinations that have numbers from the defined block

 
Property

Displays the sequential block numbers range like 1-10, 11-20 etc,
You can adjust the filter property here to select a different block for analysis by choosing another option from the drop-down combo box.

 
Number Main Type

Sets the filter for Number Main Type, allowing you to filter numbers by their type.

If the main type is set to ALL, then all numbers are included regardless of their type.

Please refer to the Filters - Types of Numbers topic for more information about filtering numbers by their type.

You can select the type of number you want to filter by from the drop-down menu.

Number Subtype

Displays or sets the filter for Number Subtype, allowing you to filter numbers by their type.

If the sub type is set to ALL, then all numbers are included regardless of their sub type, only those set in the Number Main Type property are included.

Essentially, you can filter numbers by their occurrences in various types of number configurations.

You can select the type of number you want to filter by from the drop down menu.

 
Value

Sets the condition value required for the filter to be satisfied. The value applies to Number Main Type and Number Subtype options.

For example, you can specify how many contact number types you want to include in the generated tickets that belong to the block.

Range

Displays or sets the filter's condition range value, used only when the filter's condition is set to a Range of Values.
The range value applies to Number Main Type and Number Subtype options.
 

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

This condition allows numbers contained in any Sequential 10-Number Block (e.g., 1–10, 11–20, 21–30, etc.) to be accepted or rejected without verifying other types, and no additional properties need to be configured.

When Action is Reject then:
Numbers within analyzed 10-number block will be excluded from generated tickets, and any wheel system combination containing such numbers will be rejected.

When Action is Accept then:

Numbers within analyzed 10-number block  will be included into generated tickets, and any wheel system combination containing such numbers will be accepted.

Equals Filter Value

The filter will only meet its criteria if the quantity of numbers matched in the analyzed 10-number blocks equals the specified value.

When Action is Reject then:

Generated tickets or wheel system combinations will not include selections where the exact specified numbers are matched in the 10-number blocks.

When Action is Accept then:

Generated tickets or wheel system combinations will include only selections where the exact specified numbers are matched in the 10-number blocks.

Higher than Filter Value

The filter will only meet its criteria if the quantity of numbers matched in the analyzed 10-number blocks is greater than the specified value.

When Action is Reject then:

Tickets or wheel system combinations will not include selections where numbers matched in 10-number blocks exceed the specified value.

When Action is Accept then:

Generated tickets or wheel system combinations will include only selections where numbers matched in 10-number blocks exceed the specified value.

Lower than Filter Value

The filter will only meet its criteria if the quantity of numbers matched in the analyzed 10-number blocks is less than the specified value.

When Action is Reject then:

Generated tickets or wheel system combinations will not include selections where numbers matched in 10-number blocks are below the specified value.

When Action is Accept then:  

Generated tickets or wheel system combinations will include only selections where numbers matched in 10-number blocks are below the specified value.

Range of Values

The filter will only meet its criteria if the quantity of numbers matched in the analyzed 10-number blocks falls within the specified range.

When Action is Reject then:
Generated tickets or wheel system combinations will not include selections where numbers matched in 10-number blocks are within the specified range.

When Action is Accept then:
Generated tickets or wheel system combinations will include only selections where numbers matched in 10-number blocks are within the specified range.
 

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 4
Under Filter Condition Options > Condition choose More Than Filter Value condition
 
The generated tickets or wheel system combinations will not include more than four numbers in any analyzed blocks. This is a relatively safe option, as drawing more than four numbers in such a game is very rare.

From the Visual Analyser menu select:

Grouped Numbers > Sequential 10-Block > 1 to 10 or any other block
The result of analysis is shown on a Visual Analyser's screen

This analysis method is for standard and keno games only. For Pick games this will be an equivalent for analyzing game horizontal lines.

Lottery draw numbers are usually spread across the entire Game Layout View. It is rare that all numbers are drawn just from one block of numbers.

Here is an example diagram

If number was NOT drawn from the analyzed block then the diagram will show a point in row 0

If number was drawn then diagram will show a point in row 1 or 2 etc, that depends on how many numbers were drawn.
If game numbers are like 1 3 10 22 35 45, three numbers from block 1 to 10 were drawn (1 3 10). In that case diagram will show point in row 3.

The next diagrams will show analyzes of numbers that were drawn from individual blocks and at the same time were drawn as Contact, Cold etc numbers

In this analysis method the Number Type Switch is enabled.
 

The Number Main Types are:
Contact, Outside, Hot, Cold, Odd, Even, Connected, Unconnected, Disconnected
 

The Visual Analyzer evaluates numbers in all possible combinations.

Each Number Main Type can appear individually or in combination with others.

When you change the primary number type using the Number Type Switch, diagrams display the analysis of the examined numbers and how they are represented as the primary number type in combination with other types.

Example when primary number is the Outside type:

 
etc.
 
The next diagrams will show analyzes of numbers that were drawn with pairs of numbers and at the same time Outside & Connected, Outside & Unconnected etc numbers
