Sudoku is an advanced logic-based, non-numeric, combinatoric number placement puzzle game. In traditional Sudoku, your goal is to fill a nine-by-nine grid with numbers so that every column, every row, and every single of the nine 3×3 sub-grids that make up the grid actually contain all the numbers from 1 to nine. The game is made even more difficult if you use the right strategies, since even the most guessing of a player can not ensure a perfect game. For instance, if you are playing Sudoku and you miss your mark by placing a digit in the wrong place, you will not be able to get it back again the next time you play Sudoku. Thus, it is important that you have mastered the different strategies that you can employ in this game before you play Sudoku.

First of all, you should know how to handle the Sudoku games that you play. The board that the numbers are placed on is called the playing area. This is the outer surface of the playing area that contains the hidden squares where the player has to guess as to where these numbers are placed. This is the type of Sudoku that many people know because of its simplicity; this is also why this game is usually accessible for all because of the fact that the rules can be easily understood.

The second strategy is to know where to find the different types of Sudoku games that are available in the app store. There are over seventy-five different puzzle types that the user can choose from when they download the free Sudoku games from the app store. Some of these are based on Western alphabets and numbers, which can be confusing at first; there are also a number of puzzle pieces that vary according to color and shape.

It is important to know that there are two types of Sudoku. The first is the traditional type of Sudoku that is based on the English language. This is composed of ninety numbers that make up a single sheet of paper. The second type is also based on the English language but is much longer with a thousand numbers in each cell and a total of five hundred words in a single word.

The difficulty level increases if more numbers are used in a single line. For example, if a number is written across two lines then it will be harder to solve the puzzle. However, if there is only one line then it becomes easier. The length of a line refers to the number of vertical spaces that are used up while completing a Sudoku puzzle. The logic is that the fewer lines there are, the fewer the number of numbers that will be displayed. This is why some Sudoku games may have longer grids than others.

The traditional Sudoku comes in two different variations, the nine-game version and the ninety-number version. In the ninety-numbers version, the nine squares that make up the nine-by nine grid are rearranged in nine horizontal positions. These are colored in green, orange, red and black. The challenge comes from knowing how to arrange the numbers in such a way that it can be logically predicted which colors will be revealed. The logic behind these Sudoku games is that a group of nine does not fit into any other group so the actual arrangement of the numbers must be such that it can be expected to produce the expected results. This makes it much more difficult than the traditional version.
