  We explore the low levels of the structure of the continuous Weihrauch
degrees of first-order problems. In particular, we show that there exists a
minimal discontinuous first-order degree, namely that of $\accn$, without any
determinacy assumptions. The same degree is also revealed as the least
sequentially discontinuous one, i.e. the least degree with a representative
whose restriction to some sequence converging to a limit point is still
discontinuous.
  The study of games related to continuous Weihrauch reducibility constitutes
an important ingredient in the proof of the main theorem. We present some
initial additional results about the degrees of first-order problems that can
be obtained using this approach.
