Bugs in The Software
These days, with the invention of more complex video slots, one of the most effective methods of slot hacking is to use a software bug. These can be spotted in all kinds of devices, even those that have been made by top software manufacturers. If the bug is variable, that is not such a huge deal. However, if the bug is a permanent one, scammers can use that glitch, again and again, to keep on winning.
One key time this happened was with “The Game King” slots. These slots had a bug that came up periodically — they paid out too much money to punters in particular situations. While a software bug is primarily the fault of the software developer, if someone deliberately exploits a bug to make money, this is said to be fraud and is against the rules in most casinos.
The Shaved Coin
You don’t actually need to make a fake casino chip or spend any money on making one. Instead, all you need is one chip. Then, cut a small amount off it. This allows it to be used again and again. In 1982, this simple trick was used by several scammers who cut pieces off some real chips to make a tiny change in the shape. The device accepted the chip, enabling the scammers to play. It then ejected the coin because it was unsuitable for use.
