We show, by analogy with the double square well, the energy levels of the triple square well. More specifically, it is interesting the analysis of the lowest energy levels when E < V0 because the three lowest energy levels are non-degenerate in contrast with the classical solution, and the transition between different wells is possible. As a result, we develop the corresponding energy formulae which are confirmed numerically and the tunnel effect is also described.
