For some highfalutin, letter-filling fun, get yourself a copy of The Debonair Hangman. Each page features a word or phrase for you to figure out by picking a letter and scratching off the lotto-style silver coating. If you guess right, fill in the blank—but if you’re wrong, make sure to add a part to the hangman. Even though it has a whopping 250 puzzles, this sleek-looking book is small enough to fit in your briefcase or handbag, so you’ll always be ready for a quick brain-flexing session.
