The Ticket Number is a one number from a game numbers pool like from example one of numbers from 1 to 49.
The Draw Number is one number out of all the drawn numbers, like 1 from 6.
Below Last numbers are those ticket numbers that are below of the last draw number.
Here is an example of ticket view with all ticket numbers that are below last number. (circled in yellow)
Please note that the last number from previous draw is also included as numbers to analyze.
Here below we have a sample new game numbers 10 14 15 23 28 48, they are put on the ticket view and represented as blue borders.
As we can see there is one number 48 drawn, that is drawn below the last number (number 44) from the previous draw.
Below Last Number Choosing Guide
Here is the example of low probability of numbers occurrences
Even though the numbers 45 46 48 are probable to happen, but the probability is low.
This rule is a flexible rule. Anything may happen, but, when you look at the Visual Analyser diagram, you can have some idea idea how they can be drawn.
In the case above, we would be rather careful choosing too many number below the last number if any at all.
