Calcudoku पहेली सुडोकू के समान है, लेकिन हल करने के लिए बुनियादी गणित कौशल की आवश्यकता है।

Calcudoku puzzle (also known as Mathdoku, Newdoku, or KenKen) is similar to Sudoku, but requires basic math skills to solve.

•  The goal of each puzzle is to fill a grid with digits; 1 through 4 for a 4x4 grid, 1 through 5 for a 5x5, and so on.

•  Each digit can appear only once in each row and in each column.

•  Additionally, the grid is divided into heavily outlined groups of cells called "cages".

•  Each cage has an assigned mathematical operation and a target number, that appear in the upper left corner of the cage.

•  The numbers in the cells of each cage must produce the specified target number when combined using the specified mathematical operation for that cage.

A very addictive game that helps you practice and improve your math skills.
