Ising lattice gauge theory with matter fields is generalized to a family of gauge-invariant N-state models. These models are soluble in the N ..-->.. infinity limit. In both two and three spatial dimensions the N ..-->.. infinity limits of these models possess three phases separated by lines of first-order transitions. One phase admits free charge, the second confines, and the third experiences the Higgs phenomenon. 1/N corrections are calculable and terminate the boundary between the confining and Higgs phases. A closed region of free charge persists for all N > or = 1.
