Slot machines, often referred to as "one-armed bandits," have been a cornerstone of casino gaming for over a century. Their evolution from mechanical devices to sophisticated digital platforms has only amplified their allure, leading to some of the most remarkable wins and, conversely, significant losses in gambling history.

Biggest Slot Machine Wins
