Matt Parker of Stand-up Maths explains single-pile Nim and the trick that wins it, using Dr NIM, a 1960s mechanical plastic computer that plays perfectly. He teaches the strategy so viewers can beat friends.
HN links it as a fun explanation of the purely mechanical Dr. Nim game in threads about early game computers and marble-based binary math.
