Martus, an El-Aurian con man, is being held in detention for trying to work a mark. In his cell he meets Cos, a dying alien with a strange gambling device, who tells Martus of a string of bad luck he's had, which he implies was brought on by the gambling device. After Cos dies, Martus takes the device and decides to become Quark's rival, opening another casino on the Promenade. Meanwhile, O'Brien has constructed a racquetball court to get some physical exercise, and to his chagrin, finds out Dr. Bashir plays as well. O'Brien is no match for Bashir, much to his frustration, yet he keeps challenging Bashir, who fears for the chief's health and tries to get him to stop. Written by Arnoud Tiele (imdb@tiele.nl)

Did You Know?


One of the ingredients in Quark's sedative drink is "dilithium flavoring extract oz. 435" as shown on Bashir's computer screen. This is one of the many examples of in-jokes that have been added by the show's art department throughout the series. See more »

[Martus has asked Quark for financial help to get off the station]
Quark: All right. I'll *loan* you 500 isiks. You can book passage on a cargo ship.
Martus Mazur: 1500. After all, I do have expenses.
Quark: 600.
Martus Mazur: 1200. I still have my dignity.
Quark: Dignity and an empty sack is worth the sack - Rule of Acquisition number 109.
Martus Mazur: [reluctantly] All right... 800.
Quark: Go on. I'm listening.

Non-Space 9
5 October 2018 | by HitchcocSee all my reviews

This is a silly con man episode where Quark is at the center. Chris Sarandon meets an alien who has a gambling device that seems like a toy. When the guy drops dead, Sarandon takes it. It is linked into probability and can be used in a casino. The plot involves all kinds of efforts by the participants to cheat one another while the space station experiences disruptions. There is a subplot with Bajir and O'Brien playing an interesting form of racquetball. It was just a bit of a dull episode.
