To play sudoku game, we have streamlined questions and answers that players may have viz:  The 6 fundamental questions and answers

Question #1. States the rules for completing or to play sudoku game?

Answer: The rule is simple, every row, column and box of 3×3 cells must contain the numbers 1 through 9 exactly once.

Question #2. How to do different size and shape puzzles?
Answer: The rules are identical. The size does not matter, each row, column and group of squares enclosed by the bold lines (also called a box), must contain each number only once. In some cases the boxes are not simple squares. The different size puzzles simply require a different set of numbers (or alphabet):

Puzzle type Size Box size Alphabet
Kids 4×4 2×2 1 to 4
Kids 6×6 2×3 1 to 6
Kids/Classic 9×9 3×3 1 to 9
Monster 12×12 3×4 1 to 9, A, B, C
Monster 16×16 4×4 1 to 9, 0, A to F

Question # 3. Does a it have more than one solution?

Answer: If Sudokus is properly formed, it always has only one solution. In our view, a Sudoku with more than one solution is not properly formed, but of course puzzles from other sources may have multiple answers.

Question #4. Do one need to guess?
Answer: Sudokus are always solvable using logic alone. One should never have to employ trial and error tactics.

Question #5. Your puzzle is invalid/has more than one solution.

Answer: Though we receive emails claiming that one of our puzzles is invalid or has more than one solution. So far, none of them have been correct. But, please check the following:
Double check that each row, column and 3×3 box doesn’t contain the same number twice.
Ensure that you copied all the initial clues correctly.

Question #6. How are the puzzles graded?/Why did I find today’s very hard puzzle easy?

Answer: Logic steps required to solve the puzzle determine the grading. The requirement to use any of a number of pre-defined logic steps makes a puzzle hard, and needing “hard” logic more than a few times makes a puzzle very hard. Of course, difficulty is subjective. One person may find a particular type of logic easy, while another finds it really difficult. There are often only a relatively small number of “choke” points in even a very hard puzzle. If you happen to spot the “hard” steps quickly, then you’ll fly through.
