Wavelength-Style Guessing Rules


Instead of guessing a word, this game asks a team to guess a position — somewhere between two opposing concepts on a hidden dial, like "overrated" and "underrated," or "terrible superpower" and "amazing superpower." One player can see exactly where the target sits; everyone else is working from a single clue and their own read of where that clue lands on the spectrum.

Setup

Each round, a spectrum card is chosen showing two opposite concepts at either end of a dial (one example: "Bad Superpower" to "Great Superpower"). The clue-giver privately views a hidden marker placed somewhere along that dial's hidden scale — often skewed off-center rather than sitting neatly in the middle, which is deliberately what makes the round hard. The rest of the team cannot see where the marker sits.

Giving the Clue

The clue-giver gives a single word or short phrase meant to indicate where on the spectrum they believe the target sits — not a description of the target itself, but something that, in the clue-giver's judgment, sits at roughly that same point between the two extremes. A clue toward "Bad Superpower ↔ Great Superpower" pointing at a spot two-thirds of the way toward "great" might be something like "invisibility" — genuinely useful, but not universally agreed to be the single best superpower imaginable.

Guessing

The rest of the team discusses the clue and agrees on where they think the hidden marker sits, then locks in a guess position on the dial (physically turning a pointer to that spot, in the tabletop version). The dial is then revealed: scoring is based on how close the guess landed to the actual hidden target, with a wider range of near-misses scoring partial points and a dead-on guess scoring the maximum. Because the target's exact position is hidden until the reveal, even a clue that felt obvious in discussion can land the team well off the mark.

Team Play and Rotating the Clue-Giver

Play typically alternates between two competing teams, each taking a turn as clue-giver on a fresh spectrum, so both sides get equal chances to give and to guess across a full game. Because the clue-giver's own read of "where does this sit" is inherently subjective, the game rewards a clue-giver who can predict how their specific team will interpret a word — a clue that works brilliantly with one group might completely mislead a different one, which is part of why the same spectrum card can play very differently depending on who's giving the clue.

The Design Behind It

This spectrum-guessing format was designed by Alex Hague, Justin Vickers, and Wolfgang Warsch, who published it in 2019 through their own company (originally Palm Court, later renamed CMYK) after a successful crowdfunding campaign. It won the Golden Geek Best Party Game award that same year and was widely credited with popularizing a genuinely new party-game mechanic — most social guessing games up to that point asked players to identify a specific word or phrase, not to locate a hidden point along a continuous, subjective scale.

Playing Without the Physical Dial

The format adapts easily to a no-equipment version: describe the spectrum out loud, have the clue-giver privately note or write down a target position (a number from 1–10 works fine), give a one-word clue, and have the team call out or point to a guessed position before revealing the written number. Some informal groups skip strict scoring entirely and just enjoy arguing about whether a given clue actually matched the concept it was meant to represent, which is often the more entertaining part of a round regardless of the score.

The Disagreements This Game Actually Produces

The most common real dispute is a clue that the team interprets very differently from how the clue-giver intended it — since the mechanic explicitly relies on subjective judgment, there's no way to rule a clue "wrong" the way you could in a trivia game, only closer to or farther from the hidden mark once revealed. A second common friction point is a clue-giver who accidentally gives information about the actual target's category rather than its position on the spectrum, which most groups agree undermines the format even though it isn't explicitly against the mechanic's rules.

Questions People Still Ask Mid-Game

Can the clue be more than one word? Most versions allow a short phrase rather than strictly one word, as long as it's still a single clue rather than a multi-part description.

Does the clue-giver's own team lose points if their teammates guess wrong? Scoring in most versions rewards the clue-giver's team primarily for accuracy, so yes — a badly aimed clue costs the clue-giver's own side, not the opposing team.

Is there a "correct" spot the marker has to be, or can it genuinely be anywhere on the dial? It can be placed anywhere along the full range, including close to either extreme end, which is what keeps clue-givers from assuming the target is always safely near the middle.
