We study continuous countably (strictly) monotone maps defined on a tame graph, i.e., a special Peano continuum for which the set containing branchpoints and endpoints has countable closure. In our investigation we confine ourselves to the countable Markov case. We show a necessary and sufficient condition under which a locally eventually onto, countably Markov map {f} of a tame graph {G} is conjugate to a map {g} of constant slope. In particular, we show that in the case of a Markov map {f} that corresponds to a recurrent transition matrix, the condition is satisfied for constant slope {e}{h}({f}), where {h}({f}) is the topological entropy of {f} . Moreover, we show that in our class the topological entropy {h}({f}) is achievable through horseshoes of the map {f}.
