This book is for Sudoku fans who would like to try something different. Little Killer Sudoku uses clues outside the main grid to show the sums of the numbers along the diagonals. Sometimes there may be no clues at all inside the grid. The puzzles range from easy to hard and there are two puzzles and two solutions per page. There is a bonus puzzle that uses symbols rather than the traditional numbers for anyone who would like to try it. There are a number of such puzzle books on the market and there are several symbol sets in use.
