About Mind Grid

Mind Grid turns the whole room into your stage. Your audience joins instantly by scanning a QR code with their own phone — no app to install — while you direct the entire performance from a single tablet or phone on stage.

The effect — Each person freely picks a different cell on screen. They follow your moves and, though everyone started somewhere different, every single one lands on the exact cell you predicted. Because the audience performs each step themselves, the impossible feeling lands hard: "I chose freely. How did it know?"

The finale — At the reveal, the remaining cells lift away. When the audience blows toward the screen, the cells float gently upward and scatter like magic, leaving behind the object you intended.

Stage screen & customization — Mirror the show beyond phones onto a large stage screen so the whole room shares the moment. Fill every cell with your own text and images, not just the built-in art, and put your show title, name, and logo on every audience screen. When the show ends, display your social handle or booking link to turn the room into your next audience.

Frequently Asked Questions

Do my audience need to install an app?

No. Audience members join with a regular web browser by scanning a QR code shown on the show screen, or by entering a short show code on the Mind Grid website.

What devices does the magician use?

Any modern smartphone, tablet (iPad recommended), or computer with a recent browser. The dedicated Mind Grid mobile app is in development and will be available on the App Store and Google Play.

Does Mind Grid work without internet?

The current Service requires a stable internet connection for both the magician and the audience. A dedicated "offline mode" for venues with no reliable internet is planned as a separate add-on for future release.
