Spectrum

A free "read the room" guessing game, like Wavelength

Spectrum is a free online party game in the spirit of Wavelength. Each round shows a scale between two opposites — say Cold ↔ Hot or Overrated ↔ Underrated — with a hidden target somewhere on it. One player (the clue-giver) can see the target and gives a single clue; everyone else slides to where they think it lands. The closer you guess, the more points you score, and the clue-giver is rewarded for a clue that gets the team close.

There’s no download and no signup — just create a room, share the 4-letter code, and play. It’s the same brain-on-the-same-wavelength feeling as the board game, free and instant in your browser.

How to play Spectrum

1. See the spectrum — each round shows a scale between two opposites (e.g. Cold ↔ Hot), with a hidden target on it.
2. One player gives a clue — the clue-giver sees the target and says one word or phrase that points to where it sits.
3. Everyone else guesses — slide the marker to where you think the target is.
4. Score by how close you land — the nearer your guess, the more points; then the clue-giver role passes to the next player.

Example spectrums

The scales are what make each round funny and arguable. A few examples: Useless ↔ Essential, Underrated ↔ Overrated, Weird ↔ Normal, Healthy ↔ Unhealthy, Cheap ↔ Expensive, Villain ↔ Hero. Half the fun is the debate afterward about whether the clue really pointed where the clue-giver claims.

A great party & team game

Spectrum is quick to learn, plays in 10–15 minutes, and gets funnier with a group — perfect for a games night or as an office team game. Because everyone joins from their own device, it works on a Microsoft Teams, Zoom or Discord call.
