The granddaddy of all slot machines, the Liberty Bell, was founded in 1907 when Charles Fey partnered with Mills Novelty. It still had all of the lights and bells of its predecessors but it was much easier to transport and install than the heavy cast iron slot game machines of the past.
Not too long after, several improvements were made to the machines, including lighter materials that made them much easier to transport. Some of the other improvements were replacing the heavy iron with a wood cabinet making the process of transporting and delivering the slot machine game much easier still. Around the same time, some of the casino slot games started being redone with mini themes, such as patriotic, wildlife, etc.
While these changes, which included more vibrant colors, were good, the younger players were looking for something a little more challenging and skill based. So, there was a short period of time when the slot game did not seem to be as popular as it had been in the past. Shortly after the depression the slot machine boom started again in locations such as Atlantic City and Las Vegas. Since that time, it appears that the casino slot machine has undergone generational changes that have included the video slot machine and the video poker machines.
In 1964, the first electromechanical slot machine was introduced, replacing the internal springs and levers with electrical components, which led to the more exciting flashing lights and noises. Since then, continued improvements have been made to the casino slot machine. With the advent of internet casino websites, the online slot machines have become wildly popular. The slots offered something that no table game could offer, which was the possibility of winning a hundred times your investment.
The companies that supply the casino software are constantly coming up with amazing variations for the slot game, such as great prizes and bonus features. For some people who have not been to Las Vegas or Atlantic City to see all of the excitement of a casino slot games, the realism of the virtual casinos gives them a close experience. According to the casinos, it will not be that far into the future that people will be able to use a joystick on the virtual games. We are also reminded that the term slot machine will soon be archaic and replaced by an Electronic Gaming Device (EGD) and a Video Gaming Device (VGD). And of course, they favor the coin less slot as it enables them to cut down the number of employees.
