We will be solving the above sudoku puzzle using the trick of elimination and I will be guiding you step by step to get to the solution.

**ELIMINATION TRICK STEP BY STEP**

### STEP-1: WHAT YOU NEED TO BEGIN WITH

To begin with learning sudoku trick of elimination you need following-

- A sudoku puzzle. I have enlarged this puzzle so that it is visible easily.
- A pencil and not a pen.
- An eraser.

### STEP-2: FILL IN THE “MISSING GRID”

Now, look at the puzzle which is missing the grid. The next step is to enter the number from 1-9 in a tic tac toe pattern in the left boxes. Once you put all the numbers in the grid sudoku trick to solve it becomes so much easier.

### STEP-3: ERASE “ACROSS”

The next step for this sudoku trick is as follows- for each number that is already printed or entered in the puzzle, you will start erasing that number from appropriate grids you just wrote in.

So the first number (as given in the upper right corner) is 6. Erase every other “6” from that row. Once you have completed the work of erasing, draw a line across the top of that number indicating that you have cleared that line.

### STEP-4: ERASE “DOWN”

Now we come to the next step of this sudoku trick that erases down. Now for that same number “6”, erase all the corresponding sixes in every box of the same column. Once you have completed the task of erasing all 6’s draw a line down the edge of the number 6 to indicate that you have completed this step. Now this sudoku trick becomes easier.

### STEP-5: ERASE “ALL AROUND”

Now we come to the next step of this sudoku technique. This is the last step for number 6. Erase all the 6’s over the same quadrant. Now draw a circle around the number 6 to indicate that you have completed the step. Now what you have done is eliminated all the 6’s from all the other blocks. This indicates that now 6 will not appear in any of those boxes.

### STEP-6: REPEAT FOR ALL PRE-PRINTED NUMBERS

Now redo steps 3,4 and 5 with all the numbers already entered within the puzzle. The aim of down, across and circle marks on each number is to resolve the matter of interruption if you’re for any reason interrupted in between while solving the puzzle. By drawing these lines you’ll anytime start exactly from where you left off. If the number has all three marks you’ll be able to be substantially sure that every corresponding number is eliminated from the puzzle. You’ll now very effectively dump that block now. Now yet another step we are going to come closer to solving our puzzle using this sudoku trick. Now let’s see what the results of all that erasing were.

### STEP-7: LOCATE ANSWERS

By sudoku trick of elimination done till now, you will have done so much erasing in some blocks that only one number is left. Now guess what that number is the answer for that block. Now congratulate yourself. Write that number in Big size in that block and then treat it like a pre-printed number. Eliminate all the across, down, and around numbers in the same manner as told already in Step-3, Step-4, Step-5, and done by you so many times before.

In this image red pen points point to all the answers that were taken out by you only by doing initial erasing. We have not yet begun to think and you are more than halfway down solving the puzzle using this sudoku trick.

### STEP-8: OTHER KINDS OF ELIMINATION

Now we move towards our next step of this sudoku trick. You wouldn’t always be lucky so not every time you will end up erasing all numbers except one number in the block. If this is the case then you move further and pursue the puzzle to find more eliminations. First look down at all columns and if you find a number that only appears in one block in the column then that is the answer for that block and you have moved ahead in this sudoku trick.

In this image, the pen is pointing towards number 3 and that is the only single 3 in that column so there we go very easily solving our puzzle using this sudoku trick. Now write it in large and treat it like an already printed number. See this is not thinking it’s so EASY to do.

### STEP-9: LOOK AROUND A QUADRANT

Now let us move to the next step of our sudoku trick. I know they are not really quadrants but you know what I mean, don’t you? If you look across the columns and across the rows they are all duplicates, then look in the group. If you find only one number in the group that only appears in one block then it is your answer.

See there is no guessing in the game of Sudoku. One of the situations definitely has to occur you just need to find them. In this image 5, only appears in one block in the group. Write it large and now treat it as an already printed number. Now we have come more closer to learning this sudoku trick very easily.

### STEP-10: LATHER, RINSE, REPEAT

Now we come to the last step of our sudoku trick. Eventually, you will find all the lonely numbers in their rows, columns, or groups respectively. Remember to draw the lines across, down, and around the number so that in case you are interrupted you can start from where you left off. After doing this you are there and your puzzle is solved. Compare it with our solution. And you were thinking sudoku is hard. It’s just so easy you don’t have to think and your puzzle is solved.

So this is the sudoku trick of solving the puzzle through elimination. There are many more sudoku tricks to solve the puzzle which we will learn some later day.
