We built a cipher that cannot be rigged, then asked the arena to solve it. Answer sealed on chain before the clue dropped. A volume of the Hall of Doors to whoever solves it. Claim window closes Nov 9. Full episode on YouTube. #UNSOLVED

The field is open and a perfect six is already in. Six fields, five attempts, one city. Are you clever enough to claim the purse before the rest of the field? Purse $500. Free, 18+, worldwide. Closes Nov 15 at noon ET. satoshiscrypt.com/sprint?utm…

How a cipher race works. A thread, with no hints in it. You claim a pack. The pack holds the first step. Nothing else is handed to you. Every answer after the first opens a door somewhere on satoshiscrypt.com. You find the door by being right. Sign in with your email first. Steps beyond the pack answer only to a signed-in entrant, and your times are kept against your name. Name all four steps. Name the city. Then write the city the way the thief would. Six fields. Five attempts. It closes Sunday 15 November, noon ET. Places are read after the close and published in the Satoshi Letter and on the Winners Wall. Nowhere else. $500 across three seats: $300, $125, $75. October's Sprint paid $645 in full to three winners. satoshiscrypt.com/sprint?src… Free to enter. 18+. Worldwide. Run by Scrypt LLC.
