The BriefRead this first

Ten exhibits, opened strictly in order. Clearing one unseals the next — there is no skipping ahead, and a sealed exhibit shows you nothing but its position and what it is waiting on.

Each exhibit resolves to an answer you enter; the last asks for three, filed together. The server decides. No hints exist. There is no guidance button, no nudge after twenty minutes, and nobody to ask.

The race opens for everyone at the same announced moment. From then the clock is the wall clock: the winner is whoever clears the tenth exhibit first, tracked server-side to the second. Creating your case file earlier reserves your handle and nothing else — it buys no time and costs none.

First finisher wins the prize. Ties are broken by the fewest wrong submissions, so guessing is not free even when it is within the rate limit.

The official race runs for seven days; finishes after the close still go on the board but do not count for the prize. The full rules, prize terms and winner checks are in the Terms.

One account per person. Sharing your login, or your answers, with another entrant forfeits eligibility for both parties — and because every entrant’s exhibits are generated differently, a shared answer is usually how we find out.

This is a multi-day event. There is no penalty for stepping away, sleeping, or going to work. The clock keeps running.

You must be 18 or over to enter, and you will be asked to accept the Terms and the Privacy notice when you open your case file.

Once you are inside, the dossier carries a live board: how many other entrants are sitting on each exhibit, by username, updated as they move. You will be on it too, under whatever handle you pick.
