410 Wavelength prompts & card ideas
Every card in Spectrum Party is a pair of opposites. A secret target sits somewhere between them, and one player gives a clue to point their team at it. Here is our full list of original spectrums, free to browse. Use them for your own game night, or play them online with a dial that does the scoring for you.

How to write your own Wavelength cards
A good spectrum has two ends that everyone recognises but nobody measures the same way. “Cold ↔ Hot” works because a sauna and a bath are both hot, but people will argue about which is hotter.
Avoid pairs where one end is a yes/no fact. “Fruit ↔ Vegetable” sounds fun, but the target ends up at one end or the other. Opinions (“Overhyped ↔ Underappreciated”) and fuzzy qualities (“Basic ↔ Unique”) create the best debates.
Mix easy and hard cards. Physical opposites warm a group up; abstract ones like “Style ↔ Substance” make for the most memorable rounds once everyone knows the rules.
Writing custom cards for a physical Wavelength box? Keep each side to one or two words so it fits the card, and test a few with a friend first: if you both put the same clue in the same spot, the card is too easy.
