About Wavelength 1-10, from BoardGameGeek:
Wavelength 1-10 is Wavelength but pocket sized and even simpler. Draw a number from 1 to 10, pick a topic, and give your clue. What's a 6 out of 10 pizza topping? Tomato sauce? Mushrooms maybe? Time to find out!
Instead of a spectrum and a dial, the cluegiver picks one of six topic cards on the table, draws a number card from 1 to 10, and says a single clue that (hopefully!) lands exactly on that number: a 10 for Athlete might be LeBron James, and a 1 for Chore might be cleaning toilets.
Everyone else discusses where the clue falls on the scale while the cluegiver stays silent. A perfect guess scores 2 points, off by one scores 1 point, and off by two or more scores nothing.
Play five rounds, rotating the cluegiver each time. Count your score at the end: 5 is good, 8 is really good.
