FAQ
Good to know
How many students can play?
Two or more — one clue-giver who can see the hidden target, and everyone else as the guessing team. Whole-class works beautifully.
Is this like Wavelength?
Yes — the same hidden-target dial game. The clue-giver names something between the two extremes, and the team argues its way to a spot on the dial.
Do students need devices?
No. One screen on the projector and a room full of opinions is the whole setup.
Can I use my own prompts?
Yes. Write spectrum prompts that fit your class, or let AI suggest them for your topic and grade.
Do students need accounts?
Never. Students join with a code and a name — no emails, no passwords. Teachers don't need an account to try it either.
