How to play Killer sudoku

Killer Sudoku Rules

  • Fill the numbers 1-9 into each row, column, and 3x3 subgrid of a 9x9 grid.

  • Each number can only appear once in each row, column, and 3x3 subgrid.

  • Fill in the blank cells with the numbers 1-9 so that each row, column, and 3x3 subgrid contains the numbers 1-9.

  • There are also "killer cells" in the grid. These cells contain a range of numbers, and the sum of the numbers in each killer cell must be equal to the number in the cell.

Killer Sudoku is a variation of Sudoku that adds an extra layer of complexity by adding regions to the grid. Each region has a certain number of cells that must be filled with a certain set of numbers. For example, a region might have a total of 5 cells, and the numbers 1, 2, 3, 4, and 5 must be placed in these cells.


The goal of Killer Sudoku is to fill the grid so that all of the rows, columns, 3x3 subgrids, and regions have the correct numbers.


Killer Sudoku puzzles can be more challenging than standard Sudoku puzzles because they require players to think more creatively and use more problem-solving skills. For example, players may need to use the clues outside of the regions to help them solve the puzzle, and they may also need to use logic and deduction to narrow down the possible solutions.
