Abstract
Rent A Slot Machine
The horizontal line located at the center of the slot machine's screen is called a payline. In order for a spin to win, the winning symbols must align on the payline. While slot machines first emerged, they had only one payline, positioned right in the middle of the screen. Eventually, the number increased to three, five, and more.

- Michael Friberg John Kane was on a hell of a winning streak. On July 3, 2009, he walked alone into the high-limit room at the Silverton Casino in Las Vegas and sat down at a video poker machine.
The year 2012 was the birth centenary of the pioneer microbiologist/ molecular geneticist, Salvador Luria whose life exemplified the axiom that both brilliance and serendipity have a role in defining success. In 1943 Luria along with physicist Max Delbrück demonstrated that bacteria are ideal model organisms to address fundamental questions involving heredity, triggering the emergence of the new field of molecular genetics. Their famous Fluctuation Test carried out with the bacterium Escherichia coli provided statistical evidence for the spontaneous nature of mutations, supporting the Darwinian idea of natural selection. His observations on the role of host modification in determining bacteriophage host specificity and its epigenetic transmission ultimately led to the discovery of bacterial restriction-modification systems that opened the door to recombinant DNA technology. This article is an attempt to capture the myriad contributions to science and science education by one of the founding fathers of modern genetics.

Owning a vintage slot machine is one of those fun yet daunting ideas. Many old school one-armed bandits are beautifully designed and instant conversation pieces. Plus slot fans who own a machine don’t ever have to worry about losing money to the house.
Charles August Fey, a Bavaria-born inventor, was living in San Francisco when he invented his first gambling machine in 1984. His games grew to be so popular at local bars, he quit his day job and opened a factory to start mass producing them, most notably the Liberty Bell machines in 1899. A lot of the functionality from that early game remained in place through much of the 20th century. Watch this video to see the seven mechanical actions set into motion when you pull back the bandit’s arm. The inner workings are probably a little more complex than you expect.
Given that a lot of old slot machines are hand built, it isn’t surprising that coins can get jammed on their way through the mechanism. Big warning: If your machine jams, don’t force the arm or you can break, twist or damage a part inside. Different models and makes tend to have common jam points. The Mills model shown in the above video can have coins stuck in the “elevator” section that displays the last five coins dropped into the machine. Getting the slot working again can be as simple as cleaning the gunk off of an old part. You just need to be smart when you’re disassembling and reassembling the machinery.
Okay, there are plenty of more places where a coin can get stuck and the above video demonstrates how to fix a variety of jams. It also explains how to disassemble the major parts of the machine and where common problem areas are.
Curious how an antique slot machine knows how much money a winner gets? This video shows the punch-card like communication that trips payouts and how. If you ever need to replace the reel symbols or calibrate the machine you’ll need to understand how these work. Even if you don’t ever plan on owning a machine, the metallic “circuitry” is interesting to see.

Want to own a modern slot machine? New ones have plenty more bells, whistles and dings, and also a lot more advanced parts. If you plan on getting one, you may want to have an idea of what’s inside. In addition to the classic reels, there are speakers, motherboards filled with programming chips and plenty of wires. Unless you have a way with a soldering iron you probably won’t try and fix it. But in case you do, here’s a clip from Discovery showing what’s inside.

Did you know newer slot machines are smart enough to test themselves when a problem happens? This video shows you the procedure for having the machine check its own system. The host’s desert dry delivery is also enough to make this vid worth a watch.
