Slot machines have evolved dramatically over the years, transitioning from simple mechanical devices with limited features to advanced digital and video slots. This transformation began in the 1960s and 1970s with the integration of electronic components, which enhanced graphics and sound. The 1980s and 1990s saw the introduction of interactive features and culturally themed games, providing a wider variety of betting options and bonuses. The rise of online casinos has further revolutionized the experience by increasing accessibility and introducing innovative game mechanics like progressive jackpots and gamification.
