1 Introduction

Most of the following info is from a blog article (click here to read in Spanish) written about Cirsa's involvement in pinball...

Unlike the majority of Spanish pinball manufacturers, CIRSA began with the operation and manufacture of slot machines and, for a short period (1986-1989), also manufactured pinballs, specifically 11 models.

It should be clarified that in 1983 the International Company of Recreativo SA is renamed CIRSA and becomes a holding company covering several business areas and grouping a conglomerate of subsidiary companies with more than 300 shareholder partners. Of all these companies, for the subject of pinball, we have to take into account two:

  • UNIDESA (Universal de Desarrollos Electrónicos, SA), of Barcelona founded in 1984 and located in Ctra. Castellar, 298 Terrassa - Barcelona. The main subsidiary of CIRSA for the manufacture of recreational machines, both video, as slot machines as some pinballs.
  • Stargame SA located in the Ctra. Santa Cruz de Calafell Km. 9.3 - Can Fonollar industrial estate, nº39 - Sant Boi - Barcelona, ​​with a brief history because it seems that it only manufactured pinballs for three years.

At the end of 1985 CIRSA placed an order to Williams for 500 kits each for Comet, High Speed, and Space Shuttle models. These kits were composed, among other elements, of the playfield, digital displays and other electronic elements. CIRSA also paid Williams the rights to replicate the arts and electronic cards.

Therefore, the first three pinballs were made with kits that were branded UNIDESA and that were practically the same as the American versions. But later they also decided to make replicas, at least of Space Shuttle that STARGAME manufactured and that have small differences than those made with kits. Big Guns and Pin Bot were also pinballs replicated or made with kits and branded as Unidesa and/or Stargame.

Stargame was the main entity in charge of manufacturing the pinballs of CIRSA, but initially it was an independent company that was dedicated to manufacturing pinballs. Specifically, Stargame manufactured the Space Ship and Iron Ball models. Shortly after CIRSA became a shareholder, it stayed with the company that became one of its subsidiaries.

Stargame, later as a CIRSA company, released a series of completely original models: Mephisto (probably the most popular original pinball from CIRSA), White Force and Slalom Code 0.3.

The last of the CIRSA pinballs was Sport 2000, which was released under the UNIDESA brand. It is not known if CIRSA or any of its subsidiaries manufactured any other pinballs.
