Concise Sudoku: 200 sudoku puzzles for all abilities From beginners to seasoned experts

Don’t be put off by the numbers! Although sudoku grids use the numbers 1-9, they are not maths puzzles. They are logic puzzles that involve working out the one correct location for each number within the grid (see the rules on page 1 of the book). In this handy-size book of 200 puzzles you will find a range of grids from the very easy - ideal for beginners - to the very tricky - for the old hands.
