Expert Sudoku — 300 Hard Puzzles (Paperback)

Three hundred hard sudoku, each alone on its own page, in a grid big enough to work properly in pencil. An evening puzzle with no phone, no app and nothing to scroll: something a screen cannot give, a real book you hold, write in and hand on.

Who it is for

Solvers who have outgrown the everyday sudoku and want puzzles that make them work. Every puzzle has exactly one solution, and 184 of the 300 cannot be finished with singles alone, so expect to reach for pencil marks and harder techniques. The large print suits anyone who finds small newspaper grids a strain, and it makes a straightforward gift for a keen solver.

What is inside

• A short welcome and a one-page guide: the rules, where to start, and expert tips including pencil marks, naked pairs and hidden singles.
• 300 puzzles, numbered 1 to 300 and each marked Expert, one to a page, with 24 to 28 given numbers in each.
• Grids about 14 cm (5.5 in) square, with squares about 1.5 cm wide and printed numbers about 8 mm tall, so there is room to pencil in candidates.
• Full solutions to all 300 at the back, four to a page and labelled by puzzle number.
