Games for a room full of phones

Pick up your phone. Play together.

Browser games that turn every phone's motion sensors and microphone into one shared instrument. The presenter opens a room; everyone scans a QR code and joins.

The games

  • Human Pixels

    One letter each.

    Every phone gets one letter and traces it by tilting, like a pen in the air. The presenter's screen fills with the whole paragraph as the room writes it together.

    • Tilt
    • 3–300 phones

  • Voice Choir

    Hum together.

    Each phone gets a note to hum and shows how close the singer is. The presenter's screen draws the voices as ribbons that settle into chords. Pitch is worked out on the phone; no audio is uploaded.

    • Microphone
    • 2–300 phones

  • Tidal Garden

    One room. One organism.

    A shared, living artwork. Tilt to bend glowing currents, sway to grow light and shake to set off blooms. When the room moves in sync, the garden resonates.

    • Tilt, sway, shake
    • Whole room

  • Gravity Lab

    How strong is gravity?

    Make a pendulum, time its swings with the phone's motion sensor or a stopwatch, and work out Earth's gravity. A hands-on experiment for Classes 6–8.

    • Motion or stopwatch
    • Solo or small group

How a session runs

Open a room

The presenter opens a game on a laptop or projector and creates a room. Presenter controls stay in that browser.

Scan to join

Everyone scans the QR code. Phones ask for motion or microphone access only after a tap.

Play live

Phones send small summaries a few times a second through a public relay. Nothing to install, no server to run.
