Sudoku Rules - Work Out That Puzzle, Now!

For playing the Sudoku puzzle you don’t really need to be a math scholar even though it involves a lot of number play and arrangement. It was first introduced in magazines by a famous puzzle publication by the name of Dell Magazines, which identified the game as being Number Place meaning a game of placing numbers in the seventies.

This New York publication then further popularized the initial Sudoku games, which denotes number (Su) and single placement on the board (doku) in Japanese.

Thus, it came to be that the puzzle that originated in Japan was finally taken to and accepted in Europe and America with equal enthusiasm as it proved to be a real mental challenge. But, it was not until 2005 that Sudoku gained actual international prominence with widespread excitement over newer nations and people of all ages taking to the puzzle solving with Sudoku competitions and timelines besides prizes coming in the fray.

The game of Sudoku revolves around a 9×9 grid with pre-entered numbers in it, referred to as ‘givens,’ its aim is to fill in numbers 1-9 so each figures only once in each sub grid, row and column.

Now that we have covered the basic ground for playing Sudoku, we can move on to other important rules of the puzzle solving –

Players must remember that each number should only appear once in every row, column or region; then, they must work to understand the 3 parts of solving the puzzle namely, Scanning, Marking up and Analysis.

The first process is of 2 types – cross-hatching that requires one to identify lines across a particular area so as to eliminate any digit appearing there and the second technique that requires counting the areas of the grid to check out which could be missing numbers. (The second technique is preferred by many players as it helps to speed up the corresponding search).

The next stage requires candidate numerals to be written in the cell’s subscript but when the Sudoku game appears in mags and dailies, it often is bereft of enough space to put these in, so this is better achieved in the online or electronic Sudoku game.

Another choice for Sudoku solving is to use the ‘dot’ marking on cells where it corresponds to a number in the range of 1-9; this is especially useful for printed Sudoku puzzles.

The last step, analysis, requires candidate number elimination (also known as What-if) that removes numbers from cells so that only one choice is left. Thereafter, a second scanning is conducted, which reveals the effect of contingencies, much like What-if, where 2 numbers are left and so guess-work may be required.

With different rates of problem solving from light to very difficult and computerization coming into the picture, there is no doubt about the popularity the game enjoys today as fans can customize, print and alter variations of the game to suit their preferences, including changing to larger fonts, bigger puzzles and challenge competitors! Thus, it is no wonder that Sudoku rules and tricks are fast changing and have become more fun, too – try it today to know its appeal!
