Long-form writing on puzzles, riddles, and how the brain actually solves them.
From the Sphinx's riddle in Sophocles to Wordle in your morning inbox — how puzzle culture evolved across 2,500 years. Includes Alcuin of York's medieval brain-teasers, Sam Loyd's 15-puzzle craze, Martin Gardner's Scientific American column, the strange origin story of Sudoku, and the social rituals of the daily-puzzle era.

Five classic math puzzles every curious adult should encounter at least once — the Monty Hall problem, the two envelopes paradox, the 100-prisoners-and-the-boxes puzzle, and two more. Plus a practical four-week plan for building a math-puzzle habit that doesn't feel like homework.
Why a solved puzzle releases dopamine like a small bet won. The neuroscience of the "aha" moment, the Gestalt psychology principles that govern how your eyes group dots into faces, and why pattern recognition gone wrong produces both pareidolia and conspiracy theories.
A tour of the great riddles in Western literature — Sophocles' Sphinx, Samson's wedding-feast trap, the Anglo-Saxon Exeter Book, Shakespeare's caskets in Merchant of Venice, Lewis Carroll's deliberately answerless raven, and Tolkien's Bilbo-and-Gollum contest. Each one tells you something about its author's view of language.
The "21-day habit" claim is a myth — actual habit formation takes 18 to 254 days. Here's a research-backed four-week plan for building a daily puzzle habit that survives the second-week slump, plus a recovery protocol for when life inevitably breaks the streak.
