Sudoku Seventeen: A selection of 200 special, challenging puzzles with a step-by-step guide to their solution

For a sudoku puzzle to have a single solution it needs to have at least 17 clues, although many puzzles in books and magazines typically have as many as 25 clues. You might therefore expect that 17-clue Sudokus are very challenging, and indeed some of them are. In practice they can be tackled with some easily learnt methods which reveal the puzzles to have their own special characteristics. This book continues on from the same author's "World of Sudoku"...
