Stadium
About This Machine
The IPDB listing for "Stadium" (dated June 1951) has historically attributed manufacture to Chicago Coin Machine Manufacturing Company, but that attribution is now known to be incorrect: Chicago Coin never made this game, and the actual manufacturer was Como Manufacturing Corp., which released its own 1951 title also called 'Stadium.' Because of this mix-up, the listing itself is marked for deletion, and specific gameplay details for this particular entry cannot be reliably confirmed.
What can be said is that Stadium dates from 1951, a period when electro-mechanical pinball was still developing many of the mechanics that would define the format for decades, and that it was a single-player machine. Beyond that, players and collectors researching this title should refer to Como Manufacturing's 1951 'Stadium' listing for accurate details, since this entry conflates the two games.
This mislabeling is a useful reminder of how much cross-referencing was needed to sort out manufacturer records from the early 1950s, when several companies sometimes released similarly named or themed machines in the same year.
