Game Piece: Pom poms, magnets, Lego duplos, or bottle tops painted in those colors could also be substituted.For a good Sudoku color technique, it's important to take things slowly. This isn't a game that you will win immediately - you will have to revisit the same squares over and over, gradually adding more pieces to the puzzle before you finally uncover the solution. Of course, this only adds to the sense of satisfaction you feel when you win! In this classic sudoku grid, your challenge is to get one of each color in every row, column, AND 4×4 box. The rules of Sudoku puzzles are remarkably simple. You have a large, 9x9 grid that is divided into nine 3x3 squares. You also have 81 colored balls, nine of each color. Where sudoku puzzles get challenging is when there are multiple open positions in a row or column... In these cases you may need to look at more than one part of the puzzle to figure out how to solve the puzzle. Consider a row that is missing digits 5 and 6. If that's all the information you have, you have little to do except guess. However, you could look at the column that intersects one of the blank positions in the row. If that column already has a 5 in it, you know the value that goes in the blank position MUST be 6 because putting a 5 there would violate one of the sudoku rules. This sort of mutual exclusion is a powerful way to filter out possible values in your solution, and with a little practice you can apply it with rows, columns and squares.

Look in particular for columns or rows with only two empty cells, and therefore two-color options. You may be able to eliminate one possibility based on interactions with intersecting lines and squares, making the solution clear. Suduko puzzles typically get more challenging depending on how many numbers are supplied in the initial puzzle. When there are many numbers supplied, it is easier to figure out which numbers can be put into a specific place in the puzzle. For example, if eight out of nine positions in a sudoku column already have a value, the nine position must contain the digit not already mentioned in the column. This same strategy of finding missing digits easily extends to rows or squares. Use all four colors, only once, in each column, row, and box. Move and arrange the different colors to solve the puzzles. Of course, the game isn't always so simple! You will have to look laterally, comparing columns, squares and rows as you go. It's a good idea to work by process of elimination. A single green cell means that you can eliminate green as a possibility from all the cells in that column, row and square. Now look for other colors that can be eliminated, and you might find that you're left with only one choice. Sudoku puzzles, in spite of their Japanese sounding name, was originally developed for publication in French newspapers in the late 19th century as a variation of more common magic number puzzles. The puzzle was refined and took its modern form in the United States in the later part of the 20th century, and became a world-wide phenomena after computer generated Sudoku puzzles became common around 2004.When playing Color Sudoku, start by looking at rows, columns or sub-grids that are close to being filled. Identifying missing colors from almost complete lines can lead to easy placements. Another useful strategy is to focus on a certain color at each step instead of trying to fill all colors simultaneously. Features Sudoku is a type of logic puzzle that requires you to fill in digits on a 9x9 grid. The grid starts out with some positions populated and your job is to fill in the remainder. The numbers must meet certain criteria, specifically that the same digit cannot occur more than once in any column or more than once in any row. Additionally, you'll notice the sudoku grid is divided into 9 squares, each 3x3, and a digit can also only occur within these squares.
