Grand Slam

The Grand Slam, manufactured by Petaco, S.A. of Madrid, Spain in 1973, is a Spanish electro-mechanical pinball machine and a close copy of Gottlieb's 1972 'Grand Slam,' differing mainly in that its kick-out holes score 3000 points instead of 1000. It's a good example of how Spanish manufacturers adapted popular American designs for their domestic market during this period.

Notable features include two flippers, two pop bumpers, three kick-out holes, three roto-targets, two standup targets, a star rollover, and no slingshots. The sound effects add character to the gameplay, with a bell that rings for every run scored, along with three chimes and a knocker, reinforcing the baseball theme.

The Grand Slam's design and theme are simple yet effective, with an emphasis on capturing the excitement of baseball. Its replay wheel maxes out at 15, adding a scoring ceiling that players must work within, and its history as an authorized (and eventually copied) design reflects the unusual regulatory environment for pinball manufacturing in Franco-era Spain, where machines required government security authorization before sale.
