Do you know your Naked Pair from your Hidden Triplet, and your Skyscraper from your Swordfish?

This bumper book from Words Up Games contains 300 expertly constructed, symmetrical puzzles, which will take you from the easiest to the most extreme sudokus - ideal for experienced solvers who still enjoy a few easy puzzles to get warmed up, or inexperienced solvers looking for a difficult challenge and to learn new techniques.

• Wide variety - our puzzles have been purposely constructed to include a wide range of solving techniques, starting with simple singles. As you progress through, methods such as pointing, claiming, pairs, triples, colouring, wings, fish, rectangles, forcing chains and many more will be required to finish the book
• Difficulty - the puzzles get gradually harder as you progress through the book. It's difficult to grade a sudoku accurately as solvers will be better at using certain techniques than others, but using our unique grading algorithm there are approximately 30 easy, 70 moderate, 100 hard, 70 fiendish, and 30 extreme puzzles
• Learn as you solve - new methods are introduced as you work your way through the book, allowing inexperienced solvers, with the help of readily available technique guides or step-by-step solvers if needed, to learn and practice the newly gained tools of the trade
• Solve in comfort - an easy-to-hold sized book with only two large print puzzles on each page allows plenty of space for candidates and reduces eye strain.
• Train the brain - Sudoku puzzles are a great mental workout and there is no need for trial and error as all the puzzles are solvable using pure logic, even though this may be very complex logic by the end!
• Answers included - the solution to each sudoku puzzle is included at the back of the book
