Qualuff Puzzles is a collection of acrostic puzzles that will challenge (and maybe even increase) your knowledge of trivia and vocabulary. It's great for people who like word puzzles or want to exercise their brain. Each letter of the answers to the clues is linked to a letter in a quote. You can work back and forth between the clues and the quote until you've figured out all of the letters. All of the puzzles are in English. In some puzzles the first letters of the answers spell out the source of the quote, and in other puzzles they will not. The puzzles with this feature are labeled with an A for acrostic.
