Advice on Sudoku Puzzles
Joining the ranks of the hottest and newest online games is the mathematical puzzle, Sudoku. While Final fantasy and MU indulge its users in a virtual world of fight scenes and heroes, and crossword puzzles tickle the mind for your vocabulary, Sudoku is an interesting challenge to mathematicians.
Sudoku is a Japanese abbreviation of the phrase “Suuji wa dokushin ni kagiru”, which means, “the digits must remain single”. Other names for the game are Number Place and Nampure. The game was the creation of a puzzle publisher in Japan, Nikoli Co. Ltd.
The Soduku Puzzle
The puzzle was introduced in Japan in 1986. It is a 9×9 grid, consisting of 3×3 sub grids known as regions, boxes or blocks. Unlike the traditional crossword puzzle, some of the cells are filled with numbers, while others aren’t.
You may ask what the rule of the game is. Firstly, the player must fill up the empty cells, one numeral for each cell, so that each row, each column and region would contain the numbers 1 to 9. Each number, however, must appear only once in each row, each column, and region.
There are around six million completed Sudoku puzzles. However, modifications are made from these originally completed puzzles, depending on where the numbers and blanks are placed.
These puzzles can range from the simple or easy to the moderate to the hard and difficult. Usually, the higher the level of difficulty, the more it needs deeper analysis from the gamer. Some puzzles within the same level can still even vary in terms of difficulty, so some may be harder than the rest. Other computer-generated puzzles can even be altered or modified depending on the needs or the mental capacity of the user.
The GamePlan
Solving the Sudoku puzzles require a logical approach. Basically, filling up the blank cells requires the use of three strategies, namely, Scanning, Marking Up and Analyzing. Scanning requires checking the rows (or columns) to spot which lines in a particular region may already contain the numbers. It also involves counting 1-9 in the regions, rows and cells to check for missing numbers. The next step is to mark possible numbers in each cell by writing them down as subscripts with a mechanical pencil. Analysis is simply elimination and guessing of possible numbers for each cell.
As you try to make a go at these puzzles, here are some questions that can help you solve the puzzle:
• Where do I put this number in this row or column? Scan the numbers and see of that number is already in that row or column. Make sure that you don’t repeat a number for each row, column or region.
• What row or column is nearly filled? Yes, it’s easier to start with rows, columns and regions which are nearly complete. Elimination is easier because you only have to put in two or three numbers.
