How to play

  1. Choose a built-in category or paste your own words into the custom list box.
  2. Pick a round length (30, 60, or 90 seconds) and tap Start Round.
  3. Hold the phone on your forehead facing out — tilt down for correct, up to pass (or use the on-screen buttons).
  4. When time runs out, review the recap of every word and tap Play Again to reshuffle the same list.

Pick a category — animals, movies, food, famous people, household objects, or sports — or paste in your own word list, then hand the phone to whoever's guessing. Hold it face-out on your forehead and let your team shout clues while you tilt: down means correct, up means pass, and the giant fullscreen word is readable from across the room. If tilt sensors aren't available, on-screen Correct and Pass buttons work as a full fallback so the game never stalls. After the timer runs out you get a scrollable recap of every word, sorted into correct and passed, plus a confetti celebration for a good round. It runs entirely offline with no app download and no accounts.

Frequently asked questions

What if tilt detection doesn't work on my phone or browser?
The Correct and Pass buttons on screen always work as a full fallback, no tilt permission required. Many browsers also need a one-time motion-access confirmation, which the tool requests automatically when you start a round.
Will I see the same word twice before running out of new ones?
No. Words are drawn from a shuffled deck with no repeats until every word in the list has appeared once, then it reshuffles automatically for endless rounds.
Can I make my own word list instead of using a category?
Yes — type or paste your own words (one per line) into the custom list box and it replaces the selected category entirely for that round.
