The objective is to fill the grid in with the digits 1 through 6 such that:
* Each row contains exactly one of each digit
* Each column contains exactly one of each digit
* Each bold-outlined group of cells contains digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (-), multiplication (x), and division (÷). Unlike [[Killer sudoku]], digits may repeat within a group.


Some of the techniques from sudoku and killer sudoku can be used here, but much of the process involves the listing of all the possible options and eliminating the options one by one as other information requires. One major distinction of KenKen from sudoku is that there are multiple ways to an answer. One can finish a puzzle and then erase the answers to try to solve it in a more efficient way.

If companies do not have a Wikipedia article, please create one, even if it is a stub, to prove notability. In according with Wikipedia guidelines this article should only contain companies that are notable and should not be a list of all companies headquartered in San Diego. For more information see article: 'Wikipedia:Notability (organizations and companies)' and 'Wikipedia:What Wikipedia is not'.


In the example here:
* "11+" in the leftmost column can only be "5,6"
* "2÷" in the top row must be one of "1,2", "2,4" or "3,6"
* "20x" in the top row must be "4,5".
* "6x" in the top right must be "1,1,2,3". Therefore the two "1"s must be in separate columns, thus row 1 column 5 is a "1".
* "240x" on the left side is one of "6,5,4,2" or "3,5,4,4". Either way there is a five and it must be in the right pair of cells since we have "5,6" already in column 1.
* etc


More complex KenKen problems are formed using the principles described above but omitting the +-x÷ symbol leaving them as yet another unknown to be determined.

KenKen™ is a mathematical and logical puzzle loosely similar to sudoku. It was invented by a Japanese mathematics teacher Tetsuya Miyamoto, innovator of the theory "The Art Of Teaching Without Teaching", as an 'instruction-free' method of training the brain and was later published in The Times in March 2008. It was introduced to The Times via Robert Fuhrer of Nextoy and Chess Champion Dr. David Levy and recognized for its depth and magnitude by The Times features editor, Mr. Michael Harvey. KenKen(tm) brain training puzzles are a trademark of Nextoy, LLC. Renowned toy inventor, Robert Fuhrer, founder of Nextoy discovered KenKen (aka KEN-KEN) in Japan as the original books published by educational publisher Gakken Co., Ltd. as Kashikoku naru Puzzle, and has been instrumental in introducing them to the western world.

A typical KenKen problem.
Solution to the above problem.

The objective is to fill the grid in with the digits 1 through 6 such that:

  • Each row contains exactly one of each digit
  • Each column contains exactly one of each digit
  • Each bold-outlined group of cells contains digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (-), multiplication (x), and division (÷). Unlike Killer sudoku, digits may repeat within a group.

Some of the techniques from sudoku and killer sudoku can be used here, but much of the process involves the listing of all the possible options and eliminating the options one by one as other information requires. One major distinction of KenKen from sudoku is that there are multiple ways to an answer. One can finish a puzzle and then erase the answers to try to solve it in a more efficient way.

In the example here:

  • "11+" in the leftmost column can only be "5,6"
  • "2÷" in the top row must be one of "1,2", "2,4" or "3,6"
  • "20x" in the top row must be "4,5".
  • "6x" in the top right must be "1,1,2,3". Therefore the two "1"s must be in separate columns, thus row 1 column 5 is a "1".
  • "240x" on the left side is one of "6,5,4,2" or "3,5,4,4". Either way there is a five and it must be in the right pair of cells since we have "5,6" already in column 1.
  • etc

More complex KenKen problems are formed using the principles described above but omitting the +-x÷ symbol leaving them as yet another unknown to be determined.
