With the popularity of Sudoku building day by day, it’s time to give the puzzles a challenging twist—and that’s just what this unique collection cleverly does. To start off, they follow the same simple rules as wordoku: letters replace numbers, and they’re listed beneath each grid in an easy-to-remember word, phrase, or anagram. But then, hidden in the shaded squares of the grid, is the answer to a riddle that appears on the page! Solve the puzzle, and you can solve the riddle, too. It’s a cool combination of left-brain logic with right-brain wordplay and humor, designed to exercise your gray matter and tickle your funny bone at the same time.
