Missing Letter Hidden Word Sudoku

"Classic Sudoku puzzles always use the same symbols to fill in cells: the digits 1-9.

In Word Sudoku, however, each puzzle has a different set of symbols-the letters in a word or phrase. The puzzles are a little bit harder than classic Sudoku because you have to learn the allowable symbols all over again each time you begin a new puzzle.

This book takes this idea three steps further.

First, you don't get the actual word or phrase. You get an anagram instead-a phrase that's a rearrangement of the letters of the hidden word or phrase. (For example, English and shingle are anagrams of each other.) You unveil the hidden word or phrase as you solve the puzzle.

Second, every puzzle anagram in this book shares three letters: SAX. Since you know this, these three letters are missing from each puzzle anagram.

Third, I don't stick to just 9x9 puzzles. You'll find the easy 4x4 and 6x6, the unusual 8x8, the difficult 10x10, the devilish 12x12-and the unexpected, even fiendish 5x5 and 7x7!"
