World's Series

World's Series is a single-player pin game manufactured by the Rock-Ola Manufacturing Company in 1934. Founded by David C. Rockola, the Chicago firm was one of the most prominent makers of coin-operated amusements in the 1930s before it became far better known for its jukeboxes. World's Series arrived at the height of the early-1930s pin-game craze, when Depression-era operators placed thousands of low-cost ball games in bars, cigar stores, and amusement arcades.

As a 1934 game, it predates the flipper era; play was governed by a spring-loaded plunger that propelled a ball across an inclined playfield dotted with pins and scoring pockets. There were no powered flippers and no electronic score display. According to the Pinside listing, the game had a substantial production run of roughly 50,000 units, reflecting how enormously popular simple pin games were during this period.

The machine is recorded in the Pinside database and has not yet been added to the Internet Pinball Database, so comprehensive design credits are not available.
