KenKen is a japanese puzzle game similar to Sudoku or Kakuro. You have to deal with numbers, in this case it is a 4x4 grid so you have to fill each row and column with numbers 1,2,3 and 4. Groups of boxes are surrounded by bold lines which are called cages. Cages can be one ore more in rows, columns or L shaped and each cage contains a number and the mathematical operator. To fill the cells in the cage you need to combine numbers with the operator. The more grids the harder KenKen becomes. 9x9 grids are difficult puzzles.
