The pioneering reel machine, invented by Fey in 1895, was a simple device featuring three physical drums and a limited set of icons such as liberty bells, clovers, and ace-high cards. Players tugged a handle to start the mechanical cycle, and if they landed on a winning combination, they received a payout in coins or cigars. These early machines were ingenious engineering feats that relied on complex clockwork parts to determine outcomes.

As decades passed, technology began to revolutionize the gaming landscape. In the mid-20th century, hybrid machines emerged, merging physical components with electronic controls. This enabled enhanced mechanics like instant coin dispensing and improved durability. But the game-changing innovation came in the late 20th century with the advent of digital processors.
