What are Contact & Outside Numbers
The topic Game Layout View Introduction concluded that a lottery game is like a graphical box of numbers.
Each number drawn in a game and placed on a Game Layout View can have its own surrounding field of other numbers, referred to as Contact numbers.
Here in the sample picture below is a game ticket with drawn numbers on a red background.
Numbers 4 16 21 30 43 49
To visually indicate the contact numbers, we will display them on our game layout view with a different background color. In the sample picture below, the contact numbers are painted in grey and are the numbers that surround the drawn numbers.
Please note that the lottery draw numbers (4 16 21 30 43 49) are themselves also considered a contact number.
The remaining numbers that are not part of the drawn contact numbers are referred to as the outside numbers.
In this manner, the entire game is consistently divided into two distinct groups of numbers: Contact and Outside numbers. This concept applies to all game types, including keno and pick games.
Contact & Outside Numbers Choosing Guide
In the majority of lottery drawings, and in almost every game, there is an unequal distribution of the numbers.
For example, in game 6/49 we may have like 2 contact numbers drawn and 4 outside, or 3 contact and 3 outside etc.
You can check it out how the numbers are drawn using Visual Analyser and its Types Of Numbers section.
Here is the example of bad numbers choosing:
All numbers on the ticket above are exclusively outside type numbers (circled in green). It is quite uncommon for a new lottery draw to include only outside numbers.
Here is another example of bad numbers choosing:
All numbers on the ticket above are exclusively contact type numbers (circled in green). It is quite uncommon for a new lottery draw to include only contact numbers.
Below are the optimal numbers. Some of them are contact numbers, while others are outside numbers.
How To analyze Numbers
For example, if you want to see how many Contact type numbers were drawn, select from the Visual Analyser menu:
Types of Numbers > Occurrences of Contact numbers
The diagram shows how the Contact numbers occur in general.
If numbers were not drawn as contact numbers, then a diagram will show a point in row 0. If numbers were drawn as contact numbers, then the diagram will show a point in the row indicating how many contact numbers were drawn. The next diagrams will analyze numbers that were drawn as the selected number type and in combination with other types.
Each game draw is different, and therefore, each time the contact and outside numbers are different as well.
Use the Visual Analyser feature to observe how many numbers are drawn and how often.
In the majority of games, those numbers are mixed, so it is a good idea to choose both types of numbers.
Of course, in some games, from time to time, only contact or only outside numbers are drawn.
But if that event happens, you just lose one chance out of many better chances.
Choosing both types significantly increases the number of right combinations to use and eliminates many that are unnecessary to play with.
