SZuduko is a number puzzle that the whole world is addicted to. This puzzle is a lot of fun to solve. Initially,

it seems a bit complicated and counterproductive. Solving this puzzle means placing the numbers 1 to 9 in a row and column, in a 3*3 square block.


Method1easy level

1Use counting principles to solve the puzzle. When you already know that the same number

doesn’t appear in every row, column, or nine square blocks (3*3), you can use this to choose the

correct number. The level of difficulty depends on the position of the marks given.

2Find the fixed digit. When solving a simple Sudoku puzzle, you find the fixed digit first. A certain

number is the number of points that will definitely land exactly where they should be. Starting with the digit 1, draw an imaginary line in the row and column of each square block containing the digit 1. The 3*3 square block in which a small square (box) is empty, the digit 1 will definitely come up. (See picture numbers 1 and 2)

3Repeat the same way for all numbers up to the digit 9. You’ve put some of the digits in a small square (box), so this will help you figure out the second digit that was likely to appear more than once. (See picture numbers 3 and 4. Look carefully at how issue 3 is not solved yet, but it is solved eventually).

4If you get stuck, check from the beginning. If you get stuck while solving the puzzle, check all the way back. It can be said with the claim that you have missed something, that one point due to which you cannot move forward. If you still can’t find a suggestion, put in each small square every number that is likely to be there.

See Figure 1 as an example. Mark each of the empty little square boxes where the number can appear. If the number 1 is in any 3*3 square block, then it is impossible to get the number 1 in the row or column related to them.

5Start solving the Sudoku puzzles provided in the newspaper or online: (see links below) The Sudoku that appears in the Monday and Tuesday newspapers are mostly easy. And the difficulty level of Sudoku increases as the week progresses.


6Try to solve a difficult Sudoku. The Sudoku above (picture numbers 1 to 4) is solved by a certain number only, what would you do if it wasn’t solved by a certain number only?

Method2level hard

  1. 1Start with the number 1. Fill in all the blank squares (boxes) you can find in this level as given in the easy level above. Mark all the fixed numbers as far as possible. For example, look at Figure 3, shown above, there is currently no way to solve for the number 3.
    • Hard Sudoku doesn’t solve all the numbers at the very beginning, so fill in the number of fixed numbers you can get into the blank little square. You will benefit from this when there are two or three options left in the 3*3 square block and you don’t know which number will come in the empty little square box.
  2. 2Note that in a 3*3 square block or in a column or row any two small square boxes are empty and there is a possibility of two digits appearing in them, then you enter those numbers, the other digits will be less likely to appear there: Example As in a 3*3 square block, the four smaller square boxes are empty and you’ve found out that:
    • The empty small square box A can contain the digits 1, 2, 3 or 4;
    • The empty small square box B can contain the numbers 1, 2, 3 or 4;
    • The empty small square box C can contain the numbers 3 or 4; And
    • The empty small square box D can contain the numbers 3 or 4.
      • This shows that in the small square boxes A and B, the number 3 or 4 cannot come because in these boxes only the number 1 or 2 will come. This information will help you solve the second box.
  3. 3Solving a Tough Sudoku Takes More, Too Much Time: Solving a difficult Sudoku takes a long time,
  4. but it’s still fun to solve. The more difficult, the more fun solving sudoku is. Difficult Sudoku is also
  5. solved like Easy Sudoku, but it has fewer points in the beginning. The logic of difficult sudoku puzzles is that if you know in advance which number will come in which box, it will become an easy level, not a difficult one.
    • For example, the digit 2 is twice as likely to occur in a particular nine square box (3*3 square
    • block), and is in a row or column, and you know that the digit 2 is in that particular box and any
    • will not come in the second blank box. This means that you know that the row or column
    • containing the digit 2 will not contain the digit 2 in any blank box except in a nine square box (3*3 square).
  6. 4Consider this option to solve the surest riddle correctly and quickly: In this method, in each box, mark each digit that has a chance of getting there. Mark each number in a smaller size on the top
  7. side of the box. To make this method easier, take this puzzle on a big paper. Enter all the numbers
  8. Zuduko
  9. that do not fall in that row, column or square. Once you have entered all the numbers in the sub box, then select the numbers that will appear clearly. If you follow this method for each row, your puzzle will be solved soon.

Method3samurai sudoku

  1. 1Be a Confident and High-Class Player: Samurai Sudoku Puzzle is a puzzle that only a trained Sudoku player can attempt to play. Zuduko Basically this Sudoku consists of five Sudoku inside one. The corners of each Sudoku are joined together by a Sudoku puzzle in the middle. (See picture below) These puzzles can be long and difficult.
  2. 2Keep an eye on each block that is joined. When solving these, you should always keep in mind that the four corners associated with the middle puzzle must work with both puzzles.
  3. 3Look at the rows. Look at rows that are as long as 21 small square boxes, or see them as a row made up of three separate 9 smaller squares. One of which is included with pieces of the other two.
  4. 4Solve this Sudoku puzzle as you would a normal Sudoku puzzle: remember that you can place three of the same kind in a row that connects to the middle Sudoku puzzle.

Method4Dangerous (Killer) Samurai Sudoku

  1. 1Take a look at the dangerous type of Samurai Sudoku. Its rules are slightly different and all of its grids are colored. The usual Sudoku rules are also used in this puzzle, which means that every 9 square boxes (3*3 squares) must contain the numbers 1-9.

Rules of the Dangerous (Killer) Samurai Zuduko

1Look for a smaller number in a colored block. Look for a smaller number in each colored block. This number will represent the value of each square in that block. For example, if the sum of 3 squares of a colored block is 7, then each of the squares must be 1,2, and 4, but it is up to the player to decide which points will fall in those colored squares.

2Look carefully at each colored block, many numbers come up again and again but sometimes it is possible.

3Observe the sum of the numbers. The total of the digits for every 3*3 square block, each row, and column, should be 45.

4It’s important to understand that a dangerous samurai puzzle consists of Zuduko of four examples presented in a 3*3 square box that belong to two different 9 square blocks (the big square): the rules of normal Sudoku apply in these situations as well. This means that the numbers 1-9 are used only once. For this reason, only this 4 square block is an important link in solving the complete puzzle.

puzzle solving tips Zuduko

  1. 1Look for colored blocks that have more or less total deposits. These have fewer number combinations and are therefore easier to solve.Zuduko
  2. 2Look for a group of colored blocks with one square block facing out (more) from the boundary of the 9 square blocks .
  3. 3Don’t just think of blocks that have a total of 45: sometimes it’s possible to find a digit by accumulating 2,3 or 4 points in a colored block, or more like 9 square boxes If the total is 90, 135 or 180, you can find another digit.
  4. 4Find colored blocks that intersect or have more or less the original number: for example, where one colored block with a total sum of 3 is at 90 degrees to another colored block with the original number of 4, both Calculating aZuduko block is easy because there is only one option for three digits – 1, 2 and 3, but don’t forget that the numbers 1-9 should appear only once in each row and column.
  5. 5Eliminate easy numbers: If the numbers present in the two colored small squares total plus 4, 6, 8, etc., then by logic, these two colored blocks cannot contain the numbers 2 and 2, 3 and 3, 4 and 4, etc. and thus reduce the permutation.
  6. 6Look for colored blocks that form a ‘queue’. For example, 4 colored blocks out of 2 squares form a row. Subtract the given total of four colored blocks from 45 to find the missing score.

  2. 2Be familiar with the 3 square combination. it includes
  3. 3Try Normal Sudoku before you play Killer Samurai Sudoku: Killer Samurai Sudoku is a variant of a higher level Sudoku and you are advised to go through simple and complete samurai sudoku before solving such complex puzzles. These are very difficult puzzles. It may take days to complete them. Be patient.


  • You can also practice your Sudoku skills in a book. Many books contain Sudoku puzzles. Some even have instructions on how to play them one by one so you can further improve your puzzle solving skills.
  • Compete in puzzle solving with your friends or colleagues. Copy that puzzle and see who solves the puzzle the fastest. Doing this once a week or once a day will increase your puzzle solving speed significantly.
  • Instead of writing down the numbers, imagine that each square is a grid of 3*3 dots. The point in the upper right corner is 3 and the point in the middle is 5. Adopting such a method will not cause chaos in every box.
  • With regular practice your puzzle solving speed will increase.
  • Try to find the ‘first fixed digit’.
  • Look first box then row and then column.
  • Draw the puzzle with a marker pen into a square bigger than the puzzle square given in the newspaper. Now solve the puzzle by writing the numbers in the big square clearly with a pencil.
  • Check the number twice before writing it down.
  • Use the web-page below for help. That helps a lot, but stay away from auto-fillers. What’s the fun in playing Sudoku when the computer solves the puzzle for you?zodoku
  • If you feel like your puzzle solving power is waning and you are getting tired, take a rest for a few hours. Either sleep for a while, play a game or do some household chores.


  • Before you enlist the help of a solver to solve a puzzle, try solving it yourself. And where’s the fun if someone else solves it for you?
  • Try to look at the puzzle from both sides. Instead of solving from north to south each time, try solving from east to west as well. Remember, as before crossing a road it is better to look both ways.
  • Before filling in each small square box, double-check its logic two or three times; One small mistake can ruin the whole puzzle. If you’re sure that the number 3 will fall into that square box, check three more times to see ‘why’ you think so. If you think a bit that the number 3 can be written in another square box as well, don’t put that number in any of the boxes. Sometimes, getting closer to solving the puzzle, you find that you have already written a number in the wrong place somewhere.
  • If you guess which number should come where, it is called cheating. All perfect Sudoku puzzles are solved with logic only. If there is a possibility of two digits appearing in a place and you put one of those numbers in it without any reasoning, then this is also called cheating.
