Something went wrong? What to try

Most problems fix themselves. Your answers are saved on this device first (in a private window, keep the tab open), so trying again never loses them.

You're offline: keep going, even after reloading. Brain Zap sends your answers by itself when the connection is back.

Added to your home screen (or installed on a computer), Brain Zap opens in one tap, and offline it reopens your Zap. On iPhone and iPad, the home-screen app keeps its own progress, apart from Safari's.

It's slow: if a screen or link takes more than 8 seconds, it says so. Tap Try again, or tap the link again.

"Too many requests": many people on your network used Brain Zap at the same time. Brain Zap tries again by itself after a minute, and your answers are kept.

A plain page that says "error code": our host had a short problem. Wait a moment, then reload the page.

Still stuck? Reload the page: pull down on a phone, or press Ctrl+Shift+R (Cmd+Shift+R on a Mac) on a computer.

Nothing helps? Contact us, and give us the reference shown on the error screen. It starts with BZ-.
