Fruit machine
From Tardis Wiki, the free Doctor Who reference
A fruit machine was a device used for gambling. In 2013, Nyssa won on one in the Pescadorian, having used a pound leant to her by Tegan. After Turlough enquired as to her system, Nyssa explained that she had "observed the algorithmic responses of the machine to the last three players" and that it was "all perfectly simple". The Fifth Doctor told her to remind him never to take her to Las Vegas. Turlough said he wanted to do exactly the opposite. Nyssa returned Tegan's "deposit" to her. (AUDIO: Eldrad Must Die!)
