7Word plexers are word-based puzzles that describe a word or phrase without actually spelling it out. For example, KCART would be backtrack since it is the word track spelled backwards. These kinds of puzzles are sometimes called wacky wordies or rebuses, although the latter is usually a picture-based puzzle. We have grouped our puzzles by difficulty, making the easiest level appropriate for students who have never seen word plexers before, and with the hardest level being nearly impossible to solve without help.
