## How to Play Kenken Puzzle?

The KenKen puzzle is a square grid with empty blocks. In the upper left corner of each block there is a number and an arithmetic sign. It is necessary to fill the grid so that the numbers are not repeated in the rows and columns, while the numbers inside the block as a result of the specified arithmetic operation should give the answer to the left of the sign. The number of different numbers is equal to the number of rows or columns. This means that the numbers 1 to 4 will be located in a 4 × 4 square.

## Rules KenKen Puzzle

The puzzle consists of a grid with numbers and signs of four arithmetic operations. You need to fill the rows and columns with numbers so that they contain a complete set of numbers, but are not repeated. But in the block circled with a bold line, the numbers may be repeated. The number of numbers that can be used depends on the grid size. The sign of an arithmetic operation in a block means that if this action is performed on all the numbers in the block, the number in the upper left corner of the block will be obtained. In the most complex puzzles there are no arithmetic symbols at all. Usually tasks are completed for a while. The best players fill out the grid in just a minute. And this, of course, is a real challenge for all intellectuals.

But when you solve KenKen, you really understand what you did. You begin to understand mathematics.

Learning to play KenKen is as easy as learning to play tic-tac-toe; everyone can do KenKen. You don’t have to be good at math. You just need to know how to fold.
