12 gut-instinct either-or questions reveal your brain-circuit type out of 16, then invite a friend to find your sync rate.

No trivia and no memory test, just your first instinct: run from the zombies or stock up on snacks first, mix your curry or keep it separate, quit on the spot or tell no one after winning $100 million. This free quiz takes about a minute with no sign-up. Twelve everyday-but-absurd either-or questions map how you decide, how you see things, how you express yourself, and where your energy comes from, and land you on one of 16 brain-circuit types with a name, strengths and blind spots, your best sync match and the type most likely to split from you, three small steps, and a shareable character poster. Then send an invite link to a friend, partner, or coworker. They answer without signing in, and you both see your sync rate, which questions you were in perfect sync on, and which ones you split on. A fun gut-check game, not a diagnosis.

Common questions

Is it really free?

Yes. Your result shows as soon as you finish, and the full report opens after one short ad — no sign-up, no points. If you'd rather skip ads, the annual membership removes them site-wide and opens every report directly.

Do I need an account?

Points can be bought without signing in and belong to this device’s credential; clearing browser data or changing devices may make them unrecoverable. Moving them into an account requires explicit confirmation after sign-in. Membership requires sign-in. Signing in never places an order or claims device data automatically.

Are my answers stored? Who can see them?

Your answers and result are stored on our servers and linked only to your device or account, so you can come back to your report. They're never made public and no name is needed. To delete your data, email support; signed-in users can also download their data or delete their account in account settings.

Can I take it again?

Yes, as often as you like. Earlier results stay in your history so you can compare.

How accurate is it?

Your result reflects how you answered this time. It's a good way to learn about yourself and start a conversation with friends. It's for fun and self-reflection, not a psychological or medical diagnosis; if you're struggling, please talk to a professional.
