LottoGPT: Your Smart Lottery Analysis Assistant

• Q1: How do I install the software?

  A1: The software does not require a specific installation process. Just download, unzip, and directly click on “LottoGPT” in the directory to run “LottoGPT.exe”. However, please be aware that the system must have .NET 6 environment deployed. The package comes with .NET 6 desktop runtime installer “windowsdesktop-runtime-6.0.21-win-x64.exe”. For Windows 7 users, please install the cumulative update package “Windows7_KB2533623-x64.exe” before deploying .NET 6.

• Q2: How to perform a simple number reduction operation?

  A2: To perform a simple number reduction without using filter conditions, follow these steps:

  1. Launch the software and go to the “Generate Betting Numbers” page.
  2. Click the “Smart Combination” button.
  3. In the newly opened page, select your numbers.
  4. Select the required reduction options.
  5. Click the “Start” button to begin the reduction.

  Note: What is the "Guarantee n" reduction type?

  For instance, in “ToTo Singapore 6/49”, a set of numbers consists of 6 numbers. The "Guarantee 5" type means that if the pre-reduced numbers can hit all 6, using the "Guarantee 5" reduction, you can reduce the numbers drastically while still ensuring at least 5 are hit (there’s also a chance for all 6, but not guaranteed).

  But why use this method? What is its practical significance?

  Usually, bettors may choose a dozen or even two dozen numbers. Buying all these numbers could yield a massive prize, but at a high cost. If they don't win, the loss can be substantial. Randomly discarding some numbers might accidentally miss a win. In this situation, the "Guarantee 5" reduction comes into play. It allows you to reduce the number of bets considerably while still ensuring at least 5 numbers are hit (with a chance for all 6, but not guaranteed). Its purpose is to provide a scientific and rational way to combine and filter numbers, ensuring optimal use of limited funds. This not only boosts our betting efficiency but also helps us balance risk and reward wisely.

Get_AC(numbers): Returns the AC value of a group of numbers.

• numbers: Indicates a group of numbers, which can be variables, constants, formulas or other functions.

AC value refers to the number of positive differences between every two number values (the same difference is only calculated once) minus (R-1), where R is the number of numbers.

For example, given the following set of numbers:

02 05 11 17 21 33

Calculate the difference:

• 02-05=3
• 02-11=9
• 02-17=15
• 02-21=19
• 02-33=31
• 05-11=6
• 05-17=12
• 05-21=16
• 05-33=28
• 11-17=6
• 11-21=10
• 11-33=22
• 17-21=4
• 17-33=16
• 21-33=12

These differences are: 3, 9, 15, 19, 31, 6, 12, 16, 28, 6, 10, 22, 4, 16, 12.

Since the same difference is recorded only once, we get the following non-repeating differences: 3, 4, 6, 9, 10, 12, 15, 16, 19, 22, 28, 31, a total of 12 differences value.

According to the formula AC value = number of positive differences - (R-1), where R is the number of numbers, which is 6.

Therefore, the AC value of 02 05 11 17 21 33 is: AC = 12 - (6-1) = 7.

How to use the function:

• Get_AC(N ): Returns the AC value of all numbers.
• Get_AC(N1, N3, N4, N5): returns the AC values of number 1, number 3, number 4 and number 5.
• Get_AC(NS ): Returns the AC value of all numbers and additional numbers.

Get_RecentDrawnNumbers($y@x[N]#): Returns all numbers issued y times in the last x period.

This function is used to filter out numbers that have been issued a specific number of times in the latest period according to specific conditions.

The expression "$y@x[N]#" describes the specific requirements of the formula:

• $y: Indicates the number of times out. It can be a specific value, such as "$1", or a range, such as "$1~3".
• @x: Indicates the number of periods. For example, "@1~3" means the most recent issue 1 to 3, "@7" means the most recent issue 7 issues.
• [N]: Indicates scope. For example, "[NS]" means the range of all numbers, "[N1,N3,N4]" means limited to the number 1. Within the range of number 3 and number 4. Scope is not required, if no scope is specified, it defaults to all numbers.
• #: indicates whether to consider the location. If the "#" character is added, the number at the same position is required to be counted. For example, "$2@1~3#" means all the numbers drawn twice at the same position in the last three periods.

• Get_RecentDrawnNumbers($3[N1,N2,N4,N5]): Returns all numbers drawn in the last 3 draws within the range of number 1, number 2, number 4 and number 5.

Use "#":

• Get_RecentDrawnNumbers($2@1~3#): Returns all the numbers that have been drawn 2 times in the same position in the last 3 periods.
• Get_RecentDrawnNumbers($2@1~3[N1]# ): Returns the numbers that have been drawn 2 times in the last 3 issues at position N1.

Note: The returned result may be empty, may be a single number (such as "01"), or may be multiple numbers (such as "01,05,06").

Get_CustomSUM (numbers): Returns a custom sum.

• numbers: Represents a set of numbers, which can be variables, constants, formulas, or other function functions.
• To use this function function, you need to define the value conversion for each number.
