The minimum number of given starting numbers (or clues) required for a standard 9x9 Sudoku puzzle to have a unique solution is 17. This was established through research that demonstrated that no 16-clue Sudoku puzzle can have a unique solution. However, while 17 clues can ensure uniqueness, the arrangement and distribution of these numbers also play a crucial role in determining the solvability and complexity of the puzzle.
Krazydad puzzles, known for their variety and challenging levels, each have unique solutions based on the specific arrangement of numbers in that puzzle. To find the answer to a specific Krazydad Sudoku puzzle, you would need to complete it according to Sudoku rules, ensuring that each row, column, and region contains all numbers without repetition. The answer can be found by solving the puzzle rather than providing a universal answer, as each puzzle is different.
The puzzle known as "Al Escargot" (the snail) is currently considered the hardest Sudoku puzzle. It was created by a Finnish mathematician called Arto Inkala. One of the hardest Sudoku books available is "Extreme Sudoku" by Antoine Alary, not to be confused with "X-TREME Sudoku" by Nikoli & Co. or "Sudoku Xtreme" by Christopher Monckton, which are both an order of magnitude easier.

I suppose you mean kenken. It is like sudoku but has 6 numbers instead of 9. I don't think there is a grid for that, but it used addition, subtraction, multiplication and division...to what I know. Numbers do not repeat in a row or column (similar to sudoku but there is no 3 by 3 grid, so thats one less restriction). Hope that's what you want.
Its basically a math puzzle, so a type of puzzle.
