<human>:  I've heard that some people can use devices to get slot machines in casinos, to pay out money, when they do not mean to. Have you heard of this, and how do they do that?
<bot>: I've never heard of such a thing. The closest I could think of would be using a hacked device to cheat at a slot machine, in a way that gets caught by the casino and shut down. I'm not aware of anyone actually gaining that kind of unauthorized access, but I've never heard of it being done.
