We review the chemical and kinetic freeze-out conditions in high energy heavy-ion collisions for AGS, SPS, RHIC, LHC energies. Chemical parameters are obtained using produced particle yields central while corresponding transverse momentum distributions of particles. For freeze-out, different scenarios discussed such as single double/flavor dependent surfaces. Kinetic by doing hydrodynamic inspired blast wave fit to distributions. The beam centrality dependence per charged multiplicity studied address constant criteria collisions.
