Boxer Cube © 2004 Kalkomat.
This is classic type boxing game where player inserts coins, pushes start button, hits punching bag and gets scored (score is shown on big display).
Cube's cabinet was made of metal, later to be exchanged with fiberglass. In the course the machine's top changed its shape a bit. First the machine came as one color, then there was a multitude of airbrush paint designs, which were later dropped and now cheaper sticker designs cover Cube's surface.
