Modern years

The Liberty Bell Slot Machine

The original Liberty Bell slot machine consisted of three spinning reels that had pictures of playing cards. On each reel features a picture of a cracked Liberty Bell. The game was started by pulling the lever placed at the side of the machine to set the reels in motion. The player would observe the wheels spin around and eventually come to a stop. If the reels stopped with the three Liberty Bells lined up straight, the player won the grand jackpot worth of 50 cents. The machine quickly became famous like wildfire and the culture of slot machines had started. The original slot machine created by Charles Fey can still be seen in a restaurant in Nevada

The Operator Bell was invented around 1910s. It was a slight modification of Liberty Bell. Though it had some innovative features, still it was very heavy with weight of over 100 pounds. Nonetheless, Operator Bell’s neck coin entry was improved for better fitting and the main innovative and distinctive feature is the fruit symbols, depicted on each reel (The Liberty Bell featured spades, hearts, diamonds, horseshoes and liberty bells). There were about 30,000 of such slot machines manufactured at that time. During the time of Operator Bell, America prohibited slot games. In this period of time, slot firms began producing various symbols. The BAR symbol was developed in this period.
