The desire to make leisure time more exciting and encourage healthy competition played an important role in the evolution of society. In the coin-operated machine industry, a key moment came in 1885, when the first strength tester, known as a weight-lifter, was patented in England. Players pulled its handles upwards to test their physical strength. This was the ancestor of today’s boxers, skill-testing machines that are now part of arcades, amusement parks, pubs and event spaces. Although American and Japanese companies dominated production for decades, the balance has changed. Few people know that almost 90% of global production now takes place in Poland, with Kalkomat, operating in Krakow since 1998, among the undisputed industry leaders.

The first models now considered iconic were made in Chicago, the entertainment capital of the time. Early machines were built mainly from wood and relied on simple, exceptionally durable mechanisms. Over time, sound signals such as traditional bells and lighting were added to heighten the excitement and sense of victory. In today’s age of advanced electronics, these elements, together with modern design and striking appearance, have become standard tools for attracting customers. Other strength machines, such as kickers and hammers, also developed alongside boxers and are still produced by us today.

What is the secret of their popularity? Competition is part of human nature. The natural desire to find out who is stronger, faster or better ensures that strength machines never go out of fashion. Research and the experience of venue owners also show that installing a boxer helps people release excess energy safely and can reduce aggression in entertainment venues. Above all, it is engaging fun that generates strong returns.
