Clarity, not guesswork. The Stoics trained the mind the way an athlete trains the body: daily, patiently and with honest feedback. This collection turns that training into sixty puzzles that reward calm attention over speed.
Three tiers
- Foundation, puzzles 01 to 20: generous clues, solved with scanning and single candidate logic. Build the habit.
- Discipline, puzzles 21 to 40: fewer clues. You must look harder and hold more in mind.
- Mastery, puzzles 41 to 60: sparse clues. Expect pairs, intersections and patient elimination.
