Wavelength is a social guessing game in which two teams compete to read each other's minds. Teams take turns rotating a dial to where they think a hidden bullseye is located on a spectrum. One of the players on your team — the Psychic — knows exactly where the bullseye is, and draws a card with a pair of binaries on it (such as: Job - Career, Rough - Smooth, Fantasy - Sci-Fi, Sad Song - Happy Song, etc). The Psychic must then provide a clue that is *conceptually* where the bullseye is located between those two binaries.
