Wavelength Online FAQ

Yes. Wavelength Online is completely free. It runs entirely in your browser with no account, no download, and no payment — and there are no ads or in-app purchases to unlock the full game.

No. There is nothing to install and no account to create. Open the page on any phone, tablet, or computer and start playing right away — one device is passed around the group.

Four or more works best, split into two teams. You can play with two or three, but the guessing and betting are more fun with a few voices on each side reading the clue together.

Any modern browser on a phone, tablet, or computer — Chrome, Safari, Firefox, or Edge. JavaScript needs to be enabled, which it is by default, so there is no setup.

Each round, one team tries to land a guess as close as possible to a hidden target on a spectrum between two opposite ideas. Points add up over turns, and the first team to 10 wins.

Yes. The dial is built for touch — drag the pointer with your finger — and the layout adapts to small screens, so a single phone passed around the group is all you need.

A full game to 10 points usually runs ten to fifteen minutes, which makes it easy to play a few rounds back to back or fit one in while you wait for food to arrive.

Teams alternate turns and score by how close each guess lands: 4 for a bullseye, then 3, 2, or 0. The opposing team can earn a catch-up point on a correct left-or-right bet. The first team to 10 points wins. The how-to-play guide breaks this down step by step.

Something specific enough to place on the spectrum but not so obvious it gives everything away, using a reference the whole group shares. For Cold ↔ Hot with the target near the warm end, "a fresh cup of coffee" beats "warm."

Yes, there are light synthesized sound effects for tuning, locking in, and the reveal. Tap the speaker icon in the top corner of the game to mute or unmute, and your choice is remembered on that device.

You can. With two players it works best as a cooperative challenge — see how many bullseyes you can chain together — rather than the full head-to-head team game.

Yes. Share one person's screen on the call and let each team say where to drag the pointer. Because the whole game lives on a single shared page, screen-sharing over any video app works well for a remote game night.

The tabletop party game needs a physical dial, a screen, and a box on the table. Wavelength Online keeps the same core — a hidden target, one clue, a team guess, and a left-or-right bet — but replaces the hardware with a single web page, with a new spectrum every round and automatic scoring.

You need a connection to load the page the first time. After that the game runs in your browser with no server round-trip per round, so a brief drop will not interrupt your game.

Not in the app yet — each round draws from the built-in deck. Many groups add house rules instead, agreeing that every clue must come from movies, food, or their own friend group.

Rounds draw pairs like Cold ↔ Hot, Overrated ↔ Underrated, Fantasy ↔ Sci-fi, Guilty pleasure ↔ Proud of it, and Everyday ↔ Once in a lifetime. Each one hides a target somewhere between the two poles for your clue to point at.

There is no separate app to install, but you can add Wavelength Online to your home screen from your browser's share menu, which opens it full-screen like an app. It stays a free web game with nothing to download.

Yes. The spectrums are general-audience, there are no accounts or chat, and it works well as a quick classroom warm-up or team ice-breaker.

No. This is an independent, fan-made online tribute to the spectrum-guessing genre. It is not affiliated with or endorsed by the official Wavelength board game or its publishers.
