Authored transmissions
A deliberate campaign that introduces new operations and combinations over time.
Intercept campaign
Find the message inside the machine.
Every transmission begins as silence: a line of hidden letters, a finite signal reserve, and a sequence of register puzzles standing between you and the truth.
01
Choose a letterPick any blank in the intercepted phrase.
02
Crack its registerReach the target before your moves run out.
03
Read the patternUse each revealed letter to infer the message.
Strategic layer
Signal is your lifeline.
A failed puzzle costs signal. A clean solution reveals information and builds score. When the pattern becomes clear, stop solving letters and risk a whole-message guess.
Difficulty levels
Change how much of the register is explained, then earn a matching score multiplier.
Clear objective
Decode the complete phrase before your signal disappears.
