I was surfing the web and came across these cheating 'devices.' The claim is that somehow these black boxes manipulate the system into giving additional free credits as you're feeding the machine and/or causing the machine to more likely pay out. I am 99.5% sure this is total BS. Still the chance to play TimeCrisis 3 for hours and hours at a deep discount sounds awesome. ;-)
Here is the descriptions on the website: Third and Fourth Items down
This device was developed through years of research on machines and by beta testers. It has potential to jackpot or give credits in gambling machines and fruit machines. When put in a small box and powered by 1 or 2 (9VDC) batteries, it will fit in your pocket or up your sleeve. This unit can be used as a contact induction device (soundless arc system) or EMP induction device via magnetic induction pulses which are also soundless. This device uses in excess of 1000volts so use caution. There are two ways to use this device in either mode: as you are inserting coins, adding credits or adding money to the machine you activate the device and it will cause the credits to jump higher. The other way to use the device is to use it while you are playing and you have great odds of hitting a jackpot or winning. Kit includes all parts to build a complete unit to operate in either mode.
The completed kit can be used in two modes: vacuum arc induction or magnetic induction coil mode. The device is so small you will need to coat it with epoxy and electrical tape, as a box would take up too much space. It is powered by one 9v battery, it will fit in your pocket, up your sleeve or in the palm of your hand. This unit is a contact induction device (soundless arc system) or can be converted into an EMP induction device via magnetic induction pulses which are also soundless and generated by connecting a small pinwheel coil to the output probes. This device generates around 500volts so use caution. There are two ways to use this device: as you are inserting coins, adding credits or adding money to the machine, you activate the device and it will cause the credits to jump.
