Features of Sudoku Game 

Sudokus are simple

Sudokus are puzzles that look simple but actually require deep thought to solve. There are many different varieties, ranging from very easy to very difficult. No matter what your level, there’s a Sudoku for you to try.

You don’t need to be a math whiz to solve them—and no prior experience is necessary. There are no tricks or codes to uncover. All you do is use deduction and logic to determine which numbers go in the blank spots.

Has different difficulty levels

Sudoku 24/7 puzzles come in many difficulty levels. Easy puzzles have small numbers of clues, while hard puzzles may have several sets of clues.

Given a partially completed grid and a number of additional constraints (requiring numbers to appear only once on each row or column), there are multiple possible solutions. Solutions must be unique within the constraints provided. There can never be two completely correct answers to any Sudoku puzzle (although some puzzles have no solution at all).

In general, solving Sudoku involves looking for deduced values in the partially completed grid.

Has specific rules

The rules of Sudoku are simple. The game board is a 9 x 9 grid with 81 spaces (3 x 3 squares). Each row, column, and 3 x 3 box contains 1 through 9. The object of the game is to fill in each space with a digit from 1 to 9 so that no digit appears more than once in any row, column or box.

For those who have never played before, here are the basics: 

Using a pen and paper, start with a completely blank Sudoku puzzle. Start by filling in one of the center spaces (marked in red) with a one; then use your logic skills to fill all of the other empty spaces with numbers from 1 to 9 (marked in blue). You can only place a number once per row, column or box. There are many different ways to solve this puzzle but only one correct answer out of millions.

It’s unique

No other puzzle game can match the unique challenge of Sudoku. It will give your mind a real workout as you try to figure out where each number goes. And because it’s so much fun and challenging, Sudoku will keep you entertained for hours.

You can improve your Sudoku skills in just a few minutes every day. If you’re playing the daily puzzles in newspapers or magazines, here’s a way to make the best of them.

  • Treat each puzzle as a problem in logic. Don’t try to guess the answer; instead, look for clues that will eliminate incorrect candidates. Start by looking for likely zeroes, and then fill in the rest of the grid using only those numbers.
  • Sudoku puzzles are not about guessing correctly; they’re about logic. Your job is to solve the puzzle using your mind. There are no penalties for wrong answers or for marks that are left out of the grid.
  • There are usually four or five candidates that can be eliminated from each cell. There may also be candidates that can be eliminated from several cells at once. But don’t get carried away looking for such “possibilities.” It is often better to eliminate some incorrect possibilities than to find one additional correct candidate.
  • Never use a number unless it gives you at least two additional correct candidates in different cells. This is especially important in the corners and edges. It is common to solve otherwise intractable puzzles by realizing that certain numbers must occur in these locations.

What to Expect from a Sudoku Puzzle?
