How it works

  • Pick a difficulty: Novice, Standard, Expert, or Elite. It locks after your first valid guess.
  • Each guess returns a signal trace in plain terminal characters: @ locked, ~ signal, . static, - echo.
  • Solve it to earn Echo Credits, up to 100 a day. Faster solves and fewer guesses score higher.
  • After your scored run you can replay in Practice Mode.

Scoring: Scores reward speed, fewer guesses, and harder modes.
