Kids' Killer Sudoku

Welcome to this superb new selection of 100 killer sudoku puzzles, hand-picked for your solving pleasure

The rules of killer sudoku are very simple, and are outlined below:

- Place each number from 1 - 6 exactly once in each row, column and 3x2 bold-lined box that comprise each grid

- The grid also contains sets of cells inside dashed lines (called 'cages'). Each of these cages contains a number. This is the sum total of the cells inside the cage. Therefore a '4' means that the cells in that cage sum to 4. A number cannot be repeated within a cage.

A range of 8 different difficulty levels included. Good luck and happy solving
