Tetris 2 for the Nintendo Entertainment System will seem very similar to fans of the classic NES games Tetris and Dr. Mario. The two games are essentially combined here. The player is to eliminate single square bombs by lining up similarly colored blocks (similar to virus elimination in Dr. Mario). The tools available are falling multicolored polynomials. While several are the standard shapes used in Tetris, they are not the only shapes used and some of the shapes are even disconnected.
