1. Pick what you would choose.
Today begins immediately with five curated either/or questions. There is no account and no “correct” self answer.
Play today’s five →Or take the 21-choice full profile.
One tap per trade-off builds seven transparent “this round” axes. Share a private profile challenge and a friend can complete the same round to reveal where your patterns align and diverge.

After each personal choice, guess which side the clearly labeled target panel will take. The panel configuration is visible; the label is not an identity-verification claim.
3. Make one private friend link.
After the result, create a challenge with an optional alias. A friend first predicts your five answers and then records their own. Anyone with the URL can participate until it expires, so share it intentionally.
4. Read Knowledge and Match separately.
Knowledge
How many of your friend’s picks you predicted correctly.
Match
How many choices you independently made alike.
A completed per-question comparison can show the creator’s issued choices, but never another respondent’s sheet. Neither score labels the friendship. Safe reactions keep the response lightweight: no chat, insults, or public profiles.
5. Let a private link grow carefully.
More friends can answer the same link. Exact privacy-safe group tallies appear at five total people, including the creator. Below five, the view remains visibly forming. Individual respondent sheets and least-compatible rankings remain out of bounds.
