Not So Simple Sudoku, Cryptic Edition: 300 Curious Sudokus, Comprising 100 Easy, 100 Medium, and 100 Hard Puzzles (Paperback)

This edition offers a curious twist on the classic numbers game, Sudoku.

Instead of finding the 1s, 2s, 3s, 4s, 5s, 6s, 7s, 8s, and 9s, you're looking for the !s, ?s, $s, %s, @s, +s, =s, #s, and /s.

Normal Sudoku rules still apply, but instead of numbers you're ensuring appear once, and only once, in every row, column, and nonet - it's symbols.

With three difficulty levels, each with one-hundred new puzzles, this edition is perfect for the beginner to the experienced solver.
