Their <Euclid game> turns the <Euclidean algorithm> into a contest: a legal subtraction is chosen by a player, so computing a <greatest common divisor> becomes a question about winning positions. The example connects an arithmetic algorithm with a constructive <winning strategy> in <combinatorial game theory>.
