It is true that knowledge about the history of slots will not directly improve your play, but knowing that you are a part of a tradition will do wonders for your motivation to learn.
You may be surprised to learn that the slots machine is more than a hundred years old. It was invented in 1887 by Charles Fey of California. He used three reels and five symbols in order to make the payout mechanism simple to automate. One of the symbols was the Liberty Bell, which gave the slots machine its name. The jackpot payout was for three liberty Bells. The slots machine started gaining popularity, but then the history of slots suffered a temporary setback. The anti-gambling faction managed to get it banned in California in 1909. However the ban did not last long.
The next step in the history of slots took place in 1964. The slots machine that you are familiar with was invented by Bally Manufacturing. It was the first electromechanical slots machine appropriately named Money Honey. It worked on electronic components rather than springs. The familiar sound and light effects were added. Some other features that were introduced with the Money Honey slots machine were facilities to bet multiple coins and a hopper to collect the winnings at http://kasinot.biz/.
The history of slots took a new turn in 1975 by going completely electronic, complete with the video screen. For your information Walt Fraley invented the first video slots machine in that year and named it Fortune Coin. Initially players avoided it because they did not trust the virtual reels than the physically spinning ones that they could actually see. After 1980 this technology gained acceptance and since then video slots have been subject to constant innovation.
The history of slots has come a long way to the slots that you play with on your computer from the first Liberty Bell.
