A free game like Wavelength, played on your phones
On a Scale is Letternerd’s game like Wavelength. Each round one player secretly sees a spot on a 0–10 dial between two ends, such as useless to essential, and gives a one-line clue. Everyone else places their guess on the dial, and whoever lands closest scores. It is free, runs in the browser and takes three to ten players.
What is Wavelength?
Wavelength is a social guessing board game designed by Alex Hague, Justin Vickers and Wolfgang Warsch. A card shows two opposite ends of a scale, one player secretly sees where a target sits between them and gives a clue, and their team turns a dial to where they think it is. It is played in teams around a physical dial, and its fun comes from finding out how differently your friends see the same thing.
