One secret target
The clue giver sees the hidden spot. Every other player guesses privately, so nobody can copy the loudest person in the room.

Wavelength online questions
Spectrum Guess works for friends in the same room or on a video call.
Can I play Wavelength online for free?
Yes. Spectrum Guess is CardYard's free browser-based spectrum game. One person creates a private room, then 2-12 players join with the six-character code.
Does everyone need to download an app?
No. The host and players open CardYard in a browser on a phone, tablet, or computer. There is no download required for Room play.
How do private guesses work?
The clue giver sees the hidden target. Everyone else moves a private dial on their own screen and locks it in. All guesses appear together only when the target is revealed.
Can remote friends play together?
Yes. Share the room link or code over a group chat or video call. The Room keeps clues, private dials, scores, and new rounds synchronized.
Is Spectrum Guess the official Wavelength game?
No. Spectrum Guess is CardYard's independent online spectrum guessing game. CardYard is not affiliated with or endorsed by the owners of Wavelength.
