How illusionist David Kwong crafts puzzles to ‘stretch the brain’

Illusionist David Kwong found interest in magic and puzzles by watching the smartest people he knows — his own parents — become dazzled by sleight-of-hand tricks when he was a child. Today, Kwong delights and challenges people with his crossword puzzles, found in the New York Times, and with his live stage show “the Enigmatist,” which runs March 7 through April 5 at the Repertory Theatre of St. Louis.
