Spin Wheel

The Spin Wheel pinball machine, believed to be manufactured by Chicago Coin in the late 1960s, represents a classic example of electro-mechanical pinball design from an era when mechanical innovation was at its peak. The machine's name suggests it likely featured a prominent spinning wheel mechanism, which was a popular mechanical feature during this period to add visual appeal and scoring complexity.

The game would have utilized the standard mechanical components of the era, including relay switches, stepper units, and score reels common to electro-mechanical machines. The 'Spin Wheel' mechanism was likely integrated into the scoring system, possibly offering bonus multipliers or special scoring opportunities when activated by skilled players.

While specific production numbers are not readily available, machines from this era were typically manufactured in runs of several thousand units. The late 1960s marked the twilight years of the electro-mechanical era, just before the industry's transition to solid-state electronics would revolutionize pinball design in the late 1970s. The Spin Wheel represents the engineering sophistication achieved in purely mechanical pinball machines before this technological shift.
