John Chaneski’s latest puzzle is “The Yo-Yo Quiz,” and it’s not about famous cellists or first person pronouns in Spanish. The object is to guess the missing word that can be paired with either “up” or “down” to mean different things. For example, try to guess the one-word answer here: “With ‘up,’ it means ‘to laugh uncontrollably.’ With ‘down’ it means ‘to become more strict about an issue.'” This is part of a complete episode.
