Sudoku 101

ImageFor anyone who has scan the puzzle page in the newspaper and saw a puzzle called “Sudoku” and was afraid to try it, here are some tips on getting started. If you can, on Mondays and Tuesdays, most newspapers post the easiest.

This puzzle is a level 1 means the easiest. Some newspapers have levels up to five.

Here is some example on how to solve Sudoku.  Remember the objective of the puzzle is to put the numbers 1-9 in every row, column, and 3×3 square block.

Here is step that you can take. As you I scan the puzzle, I try to look for the most visible numbers. In this puzzle, there are a lot of 7s, 9s, 2s, 5s and 4s. These can be easily eliminated. I would start with the 7. In the second box between the 1 and 5. Reason is – the first box the 7 is in the middle occupy that row, the seven in box three is in the bottom row, so the only placed that the 7 can go is between the 1 and the 5.  As I scan the puzzle, I see that I can put a 2 in the ninth box between the 1 and the 8. The reason is the 2 in the seventh box is on the top and the 2 in the eighth box is on the bottom, so the only place that the 2 can go it is between the 1 and the 8. You see how easy that is.  I can now eliminate another 7, the seven in box 2 controls the middle, and the 7 in the fifth box controls the last row. The only place is the 7 can go in the eighth box is between the 4 and 3.

You can easily eliminate another 7 in the ninth box.  In the ninth box, only two numbers is needed, the 3 and the 6. Guess where the 3 is going. If you pick between the 7 and five you are correct. Because the 3 in box six, occupy that row.

This is the end of session one.
