This paper investigates two-particle lattice Schrödinger operators on the three-dimensional cubic lattice Z3, focusing on the spectral properties influenced by coupling constants for on-site and nearest-neighbor interactions. It identifies critical curves and points in the parameter space that determine the number of eigenvalues below and above the essential spectrum, revealing the potential for up to three bound states. The study extends to arbitrary quasi-momentum, providing lower bounds for eigenvalues a
