The One-Armed Bandit Era

Slot machines gained popularity in the early 20th century, earning the nickname “one-armed bandits” due to their lever mechanism and tendency to empty players’ wallets. These machines proliferated in bars, saloons, and clubs, with operators often modifying them to reduce the odds of winning.
