The total number of valid Sudoku solutions for a standard 9x9 grid is approximately 6.67 billion (or 6.67 × 10^9). However, the exact number is 6,670,903,752,021,072,936,960, which is a result of combinatorial calculations. Each configuration must adhere to the rules of Sudoku, where every row, column, and 3x3 subgrid contains the digits 1 through 9 exactly once. This immense number reflects the complexity and variety of Sudoku puzzles.
Just 1. The solution is a set of 81 integers, comprising 9 lots of the digits 1 to 9.

The goal of a Sudoku puzzle is to have one of each numbers 1-9 in each row, column, and 9 x 9 box on the grid. There are other variations but this is the most common setup.
The mechanics involved in sudoku follow the principal, that any 3x3 grid can be filled with the numbers 1-9, every row can have 1-9, and every column can have 1-9, to eventually have a complete 9x9 grid filled with the numbers 1-9, where no numbers in any row, column, or 3x3 grid have two of the same number
Sudoku is a game that requires players to fill squares with numbers so that every column, row, and large square contains the numbers from 1 to 9 without repetition. The word Sudoku stems from a Japanese phrase that means single digit.
In Sudoku, the "sum" typically refers to the total of the numbers in a row, column, or region (usually a 3x3 subgrid) that must equal the same set of numbers. In a standard 9x9 Sudoku puzzle, each row, column, and 3x3 region must contain the digits 1 through 9 without repetition. Therefore, the sum of the numbers in each row, column, or region is always 45, since the sum of the numbers 1 to 9 is 45. This characteristic helps ensure that each area of the grid is filled correctly.
The numbers 1-9 have to be in each bix, row and column. So if you have one with 8 numbers, you can work out the last one. And you can see where a number goes in a box if it's in that row or column, you can't put it in that row or column in the box.
