KenKen is the hottest puzzle craze since Sudoku. It combines the logic of a Sudoku puzzle with arithmetic. You have to add, subtract, multiply and divide to arrive at the numbers given in KenKen puzzle. 

In KenKen, like Sudoku, there is a grid of 4×4, 6×6, 8×8, or 9×9 cells. That means the grid has 16, 36, 64 or 81 cells. The puzzle can actually be even larger, but those are for really advanced solvers. In both kinds of puzzles, you must have all the digits in one row. In other words, if a row has 4 cells, like in a 16-grid puzzle, you must use the numbers 1-4 in each row, and in each column. No digit may be left out of row or column, nor may there be duplicates in a row or a column. 

So far, that’s totally easy to understand. If you look at a puzzle, you can see what I mean in a second. 

The diabolical cleverness of KenKen, which sets it apart from Sudoku, is that:

• some adjacent groups of cells have a thick border around them. Those groups are called “cages.” Each cage has a number printed in it, along with an operation sign. 

• The cells within that cage must be filled with the digits that will amount to the number given. Let’s say the cage has two cells surrounded by a thick border, the number in it is 6, and the operation sign is multiplication (x). That tells you that you must find two numbers that multiply to 6.

 You may be tempted to say, “That’s easy. The answer is 2 x 3!” But don’t jump to conclusions! The answer could just as well be 6 x 1. Furthermore, you don’t immediately know which of the two cells the 2, 3, 6 or 1 belong in. You have to find that out from looking at the other cages and narrowing down your possibilities. 

It takes about two minutes to learn how to do KenKen, but it can take years to master. There’s something for all levels of solvers. 

Good math teachers will look into this puzzle and learn some strategy, then introduce the puzzles to their students. There are very inexpensive books of KenKen, as well as online sites where you can download free puzzles. One of them is http://kenken.com

Once you understand how KenKen really works, you will start learning all about factoring, exponents, and mathematical logic. You won’t need a workbook, and there are no grades (if the teacher is smart). The only stress is the gentle strain on your brain, and you’ll be developing that brain with every KenKen puzzle you solve. 

It’s easy to get good at KenKen with some practice. The nice thing about the practice is that you won’t be able to stop. KenKen is the most addictive puzzle around!

Imagine a student being able to hone his or her basic math skills without worksheets, flash cards, charts, rote-memorization, or quizzes. Imagine that student loving math like never before!

KenKen was invented by Tetsuya Miyamoto, a Japanese math teacher who says, “I believe that if you give children good learning materials, they will think and learn and grow on their own.” If you teach yourself, your child or your students basic math with KenKen, they will develop a lifelong love of mathematics, and you will have done them a wonderful favor.

If you’re fond of playing puzzles, solving math problems, and think logic reasoning you can actually combine them all in playing the Sudoku puzzle.

For you to know, sudoku was first seen in a magazine published in New York in the late 70’s by specialist puzzle publisher Dell Magazines under the name of Number Place. “Su” means number in Japanese, and “doku” means the single place on the puzzle board so that each numeral can be fitted into. Although its name sounds like Japanese, its origins came from Europe and America in which the game shows the very best in thinking and reasoning. Sudoku initially caught Japan in 1986 and gained international prominence in 2005. Unlike many other games that were known within the span of time, nothing can beat Sudoku’s challenge.

Sudoku, commonly known as the Number Place, is a logic type placement puzzle. The aim of the puzzle is to place numerical digits from 1 to 9 in each cell of a 9×9 grids that is made up of 3×3 subgrids or regions. To start playing the game, you are given in some empty cells numerals which are called “givens”. The goal of the puzzle is to put the numbers 1-9 to which it must contain only once in each subgrids, rows, and columns.

Basic rules

Rules in playing the game are very simple:

•  Sudoku is played over a 9×9 grid, divided in 3×3 subgrid.

•  Begins the play with some given numerals from 1-9 that are placed in grid cells.

•  A number can only appear once on each row.

•  A numeral can only appear once on each column.

•  Digit can only appear once on each region.

Now you finally know the basic rules in playing the game, but you’re really just starting the process of making solutions to how finish the game. There are some solutions methods that can help you and these are:

•  Scanning- it can be performed from the very beginning and throughout the solution process. Scanning basically has two techniques, first the cross-hatching. Cross-hatching technique can identify which line in a particular region may contain a digit that can be eliminated. The second is counting the region, columns and rows in identifying missing numbers. Counting based upon the last digit discovered may actually speed up the corresponding search.

•  Marking Up- the candidate numbers are simply written in subscript in the cell. The disadvantage of this is that some first puzzles are printed in magazines and newspapers which are usually small to accommodate many preferred numbers. Unlike to some newly designed Sudoku game board, all inputs are done electronically. You can also use a pattern of dots within the cell, wherein the position of the dot corresponds a number from 1-9. Dot notation can be an advantage to a sudoku that is printed in paper. In playing sudoku in print, using a sharp pencil with an eraser is highly recommended.

•  By Analysis- you can approach the game by either “candidate elimination or “what if”. In candidate elimination, numerals from one or more cells are eliminated and leaving just one choice. After each answer is placed, another scan can be done. You can check to see the effect of the contingencies. In “what if” approach, a cell can be placed with two candidate numbers then a guess should be made.

Difficulty ratings

Published Sudoku puzzles are ranked depending of rate of difficulty. For you to understand, the numbers that are given has nothing to do on a puzzle’s difficulty. A sudoku puzzle with less number of givens may be very easy for you to solve. A sudoku puzzle with more number of givens can still be very difficult for you to solve as the difficulty rate of the puzzle depends on the relevance and positioning of the given numerals rather than the number of given placed in the grids.

Computer solvers find the range of difficulties for a human to find a certain solution, based on the complexity of the techniques needed. For in this kind of estimation allows publishers to take Sudoku puzzles to be very demanding. Some sort of publications rate their Sudoku puzzles into four levels are “easy”, “intermediate”, “hard”, and “challenging” are set.

So, by playing the “fastest growing puzzle in the world”, you can be sure to challenge your way of thinking and have fun in the process.

Career Expert

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!

Sudoku is a very interesting and addicting number puzzle played in almost all parts and sections of the globe. It is an exciting and very thrilling game. But at times, Sudoku can be tricky and very difficult.

The objective of the game is to fill in all numbers from one to nine in each and every cell in the given grid. Numbers should not repeat in any column, row or three x three block.

How to start solving a Sudoku puzzle? The following steps will help a player to solve any sudoku easy or difficult.

Easy Sudoku

1. be careful while solving the puzzle. Now that you already know duplication of numbers isn’t allowed, you can use it as a hint for considering other numbers. Always remember, more difficult the given Sudoku, harder it will be to start.

2. While solving any easy Sudoku, you should first prioritize your search for possibilities. They are the numbers which are possible in the column, row or block. So if you know the possible numbers, it will be easier to choose whichever number is suitable for a particular cell.

3. Start your work from number one till you are on your way towards number nine. Since you already filled in some numbers, this will be your clue to search for other numbers to be filled.

4. If you become confused, you can go back and make sure to have a look at every number you have filled in already. This will surely help you to know if there is any number you have missed. Once everything gets settled, you can go on with the puzzle and try to complete it. If you still can’t find the problem, label each three x three box with numbers which can possibly go into the box. Example, if an empty box is left. Fill it with possible numbers to see the result of your action.

5. It is advisable to begin your play in a magazine or newspaper. There are magazines or newspapers, which have sudoku. Easy puzzles usually come out during either Monday or Tuesday. The difficult ones come out the days that follow.

Hard Sudoku

1. Start with number 1. Use the same logic used by you in the easy version to complete every empty block, column and row with all possible numbers. Put possibilities if necessary. They’ll help you at a later stage if you have 2 or 3 choices for each cell but can’t remember them all.

2. If two cells in any row, column or block is one of the two numbers, remove the other possibilities using it. Example, if in a three x three block, four empty cells are there, you have established: cell A and cell B can be one, two, three, four; cell C and cell D can be three or four, you’ll know cell A and cell B can never have three or four as they already have one or two. Cell C and cell D should be three or four. This information can be quite helpful to complete other boxes given.

3. A hard Sudoku will consume more time. It can even take few days to complete, but they can provide players more fun, contentment and enjoyment after they have solved the puzzle. It is just the same as an easy Sudoku – both of them will give you very less clues to start with. The best technique of solving the hard version is to know the possible digits which can go into each box. In case you have two numbers for a single 3 x 3 box, column or row, decide which number should fill each of the locations. Though this may be confusing, when you apply it, you’ll realize that it is simple and quite useful.

4. Visit the net. There are lots of sites that provide puzzles – easy to hard. Practice some of the sample puzzles and prepare for a more complicated puzzle.

Follow these steps to solve the Sudoku and find out that however difficult it may seem, in the end, you will feel incomparably excited and have fun.
