We call the category $\mu $-bicomplete if every $\mu $-term defines a functor.

We show that $\mu $-terms and parity games are equivalent, meaning that they define the same property of being $\mu $-bicomplete.

AB - For an arbitrary category, we consider the least class of functors containing the projections and closed under finite products, finite coproducts, parameterized initial algebras and parameterized final coalgebras, i.e. the class of functors that are definable by $\mu $-terms. We call the category $\mu $-bicomplete if every $\mu $-term defines a functor. We provide concrete examples of such categories and explicitly characterize this class of functors for the category of sets and functions. This goal is achieved through parity games: we associate to each game an algebraic expression and turn the game into a term of a categorical theory. We show that $\mu $-terms and parity games are equivalent, meaning that they define the same property of being $\mu $-bicomplete. Finally, the interpretation of a parity game in the category of sets is shown to be the set of deterministic winning strategies for a chosen player.
