How to use this collection

Choose shared reference points

Start with food, everyday objects or familiar places. A useful category lets everyone interpret the clue; a very specific fandom works best only when the whole group knows it.

Turn a theme into a spectrum

A theme such as travel becomes playable when it has two endpoints, such as relaxing and stressful. Keep those endpoints distinct, then choose a clue that suggests the hidden target.

Use the right collection

This page organizes category themes. For complete pairs with low, middle and high clue examples, use the ready-to-use prompts guide. For the dial, private target and scoring, open Spectrum Guess.

Questions, answered

What are some funny Wavelength categories?

Try unusual pets: manageable ↔ terrible idea, with a dragon in a studio apartment as an example clue. Robot jobs: plausible ↔ ridiculous and silly inventions: would buy ↔ would avoid also work well. Use the sample clues to understand the scale, then invent one for your hidden target.

Where should an example clue sit on the spectrum?

There is no universal answer. The examples suggest a direction, but the clue giver chooses a clue for the hidden target and the group interprets it. Talk about the result after revealing the target.
