About
Ciphers, connected fiction, and things worth owning.
Scrypt is a puzzle house run from Louisville, Kentucky. We build ciphers that reward careful minds, a story that rewards the people who stay with it, and objects made well enough to keep.
Our solvers come from all over the world. Recent winners played from Southeast Asia. The work is the same wherever you sit: read closely, think clearly, and be the first to get it right.
Every night
The Oracle
Each night a cipher door opens, marked with a Roman numeral. Solve one and you earn a head start in the next Sprint.
Every month
The Sprint
A city cipher-race with a real purse, published before the race opens. A city pack is released, solvers race the clock, and the board ranks them by time.
Entry is free, with nothing to buy. Anyone eighteen or older may enter, anywhere in the world. It is a contest of skill from start to finish.
The story
Madrigal
The Making of Madrigal is our serialized audio course: a long story told in episodes, and the thread the rest of Scrypt hangs on.
Things worth owning
The Shop
Limited, numbered and carefully made. Everything we sell carries a hidden layer for the reader who looks closely. What it is, and where, we never announce.
At home
Local partners
We bring puzzle nights and puzzle hunts to Louisville businesses, free to the venue. If you run a place where people like to gather, we would like to hear from you.
How we run it
- Free to enter. Nothing you buy changes your standing or your odds.
- A contest of skill. Not a raffle, not a lottery. The best solver wins.
- Published before it starts. The purse and the rules are public before any race opens.
- One accountable organizer. Scrypt LLC, a Kentucky limited liability company, runs every contest on this site.
