Killer Sudoku

Killer sudoku is a hugely popular twist on the original sudoku puzzle game. Every grid includes a series of cages with numbers inside. The cells that comprise those cages must add up to the numbers within them, all while following the rules of regular sudoku. It adds a whole new dimension to the classic game.

Killer sudoku is sometimes also known as sumdoku, sum doku, sumoku, addoku, samunamupure, or even killer su doku.
