The Early Years
Slot games were first introduced to traditional casinos just before WWII. The first machines were cumbersome and loud, however, and were not incredibly popular game to play upon their initial release due to their flashiness. In the late '30s, however, slot machine companies finally developed a way to mute the sound of these machines, making them more appealing to casino customers.
Additions and Improvements
Though the first online slot games were relatively simplistic and boasted only meager winnings, as time went on slots game machine manufacturers add several embellishments to these machines. Some of the most significant of these add-ons included enhanced jackpots, which offered larger payouts, and special themes that added a unique element to each machine.
Slot machines have come a long way from their days in early 20th century casinos. The thematic variations in the machines gambling games have expanded, the payoffs are bigger, and with the advent of the Internet, slot machines have appeared in digital form. While the coin slots have been replaced by electronic money transfers and computer graphics, they still hold an enduring appeal for gamblers everywhere.
