Slot games have been a frequent and favorite activity for over a century now. It is widely believed that the first slot machine was constructed by Charles Fey in 1894 in San Francisco. It was called the Liberty Bell, and it featured three reels with an automated payout system; far ahead of its time. Many versions of the Liberty Bell are used in several physical casinos even today! Slot machines have evolved in leaps and bounds by now, but their basic concept remains the same. Similarly, though the strategies of playing slots have changed over the years, their fundamental playing approach still retains their core structure.
