How the head start is earned
Every one of these is still unclaimed.
A door stays open until someone claims it. Solve any one of them before the next pack drops and you hold that pack, and its portal, forty-eight hours before the field.
One claim per solver per month. Your first solved door of the month is the one that counts, so the door you pick is yours to choose — and last month’s winners start the next race even with everyone else.
63 doors stand open
See all →In a world of waking dreams, the prophecies of the present echo across the ages. Decipher them, and you hold the present in your palm.
Every month
The cycle repeats.
The Doors
Nightly ciphers. Solve one and earn a forty-eight hour head start in the Sprint. One claim per solver each month, worldwide, free.
The Sprint
On the first, the sealed pack goes to the solvers who earned it, and their portal opens on the second. On the fourth the gates open and the full field joins the race.
The Race
The portal opens at a stated hour. Correct entries are ranked under the published rules, and the places are announced in the Letter on the fifteenth — nowhere else.
Each Sprint carries a fixed purse, announced before it opens. A seat no one claims rolls forward into the next month rather than returning to the house — and the purse grows as the field does. Every fifteenth, a letter arrives from Satoshi carrying its own cipher and its own reward for whoever reads it properly.
Sprint — Next
City Unknown
The fourth Sprint. The city is revealed by solving and by nothing else, which is why it has no other name. Free to enter, 18+, anywhere in the world.
