How To Solve A Sudoku Puzzle: Remove Across

Next, you use the eraser to remove the number that already appeared in the same row. Let’s start with row by row. It’s easier for you to follow and avoid repeating the number. For example, you start with removing the number 6 in the first row which was preprinted. Then, put a cross line on the top of that number to make it clearer for the next steps.

Then, you continue to remove the repeated digit in the same row. You can do it from right to left or conversely. For instance, you also remove the number 6 in missing grids on the same column that this number lies on. After that, you also put a vertical line beside the preprinted number 6 as a sign.

How To Solve A Sudoku Puzzle: Remove All-Around

In this step, you continue to erase the repeated number in the same sub-grid. For example, there is a ‘6’ in the top left corner grid. So, you remove all the ‘6’s in the missing grids in that sub-grid that you filled in before. Also, you put a circle on the preprinted number 6 to indicate that there is no ‘6’ repeated in that sub-grid.

You also do these steps with other rows, columns, and sub-grids. You need to do it one by one to avoid making mistakes because the puzzle can be very complicated and tangled. If you do not follow these steps orderly for every single column, row, and sub-grid, you can make a mess.

You shouldn’t try to be multitasking in this game because many puzzles are messier than you think. Make sure that you do step-by-step for each preprinted number. Complete removing all repeated ‘6’s in its row, column, and sub-grid before moving to the next preprinted number.

Put The Right Numbers In The Blocks

After removing repeated numbers, you can solve several blocks. Players will notice that there are some grids in which there is only one digit left. It’s also the right number for that block. Then, you can use a pen to write down that answer into the block.

Put the found number in the right block

However, not all blocks can be solved at once. You need to repeat the process of removing across, down, and around again. This time, you treat these founded numbers as preprinted ones and repeat the removing process.

Look Up The Only Number In A Group

Some puzzles can be so complicated and messy that you cannot find the only number left after doing elimination. So, you can look around in nine blocks of a sub-grid. If you see a number that appears once in all the sub-grid although it can stand with other numbers in its block, it’s still the answer you are finding.

Continue to find other numbers

For example, in this sub-grid, there is only a ‘3’ left in this sub-grid located on the top right corner of the puzzle. Moreover, there is no other ‘3’ appearing in that sub-gird. So, ‘3’ is the right answer for that block. Write it down and treat it as a preprinted digit.
