The earliest slot machines had 50 card symbols and constituted of 5 drums. These machines didn't pay in terms of money directly, and the bad part about them was that the drums could be tempered with by the owner, thereby hugely bringing the winning odds of the player.
Charles Fey was the person who invented the first machine in 1881, which contained three reels. Given the appellation of the Liberty bell, cast iron was majorly used for the creation of this machine. Quite different from the machines we see and play at today, with push buttons and even video features, this slot machine was purely mechanical-and one can understand the job of this mechanical equipment which was put together inside the machine was to create winning combinations, a task that is now in our present day world is totally taken care of by computers and chips. A long way indeed-the pulley which was used in these mechanical machines has vanished totally.
Instead of money, the winner would sometimes get drinks and cigarettes, or simply candies!
The mechanical machines underwent a sea change with the pioneering of the Pinball machine manufacturer which came up with an electrical machine in the year 1963, which had features like sounds and lights! For the players also this was a big change-since it now became almost impossible to cheat such machines. Perhaps the most significant of the new introduction was the beginning of the era of multiple slots.
The revolution hit again in during the 1980s, when a man called Inge Telnaus-who invented the concept of a 'virtual reel', and also implemented it. Hence, this way, the casinos did away with the traditional reels and this new virtual reel became a huge hit. A computer program is run and these reels are given random numbers.
What happens is that each combination of symbols is given a sequence in the list of the numbers, which the passes through the chip. First, this assignment is for those combination which are either non-win or low-paying combinations. The moment you push the button determines your combination-since this sequence of numbers which is running in the chip stops on the push of the button.
This chip is called the Random Number generator, which starts up to perform the job of outputting an independent and unbiased winning combination.
In online slot games, this machinery is not present, even though the main principle remains the same.
