No, you can do Sudoku with letters or shapes sometimes. You don't actually have to add or subtract or do math calculations when playing it.
Sudoku
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.
I am assuming you are referring to a normal 3x3 sudoku grid, where you can only use the numbers 1-9 once in the grid, and by prime number you mean the 3digit number across and down the grid must be prime? For a number to be prime, it must end in 1, 3, 7 or 9. There are 5 places on the Sudoku grid for a number to finish and as you can only use a number once in sudoku you have one place left where the number can not be prime. This means the most you can have is 5 prime numbers.
Sudoku is a noun.
