Fifteen doors. Every one of them locked. A million behind the last.
Three floors, a corridor on each, a number on every door. The numbers are not
the order. The building is drawn fresh every game, so nothing you learned last
time helps you now.
What opens the next door is hidden in the rooms behind you. Search the
furniture, read what you find, work out the rest. Every find is labelled with
what it opens — and nothing beyond that is explained.
The locks are not all made of digits. What stands on each door, you will see
when you get to it.
THE LAST ROOM
A vault, and three minutes on it. Run over and the money starts melting —
though the game does not end. Losing everything on the final step would be too
cruel; a shrinking pile presses harder than a lost one.
Fifteen minutes is the full million. Take longer and it costs twenty thousand
a minute. Everything you carry out adds up, game after game, and the total is
what stands in the leaderboard — not one lucky run.
IT PLAYS FAIR
No dice, no luck, no guessing. Every code follows from what you already have.
Every building is solved before you are let into it. There is always a way
through, and every lock has exactly one answer.
Clues drift backwards along the route and never forwards. You cannot be locked
out of a lock.
ALSO
Everything is drawn in code — not a single image file in the whole app.
No ads. No hints for sale. No energy to wait for. There is one purchase and it
is a thank-you: a star by your name in the leaderboard, and nothing else.

The leaderboard is back.
Everything you carry out adds up again and goes to the global table: your place,
a name you can change, and a star beside everyone who said thank you.
