Falow and his Wadi delegates were eager to play games. They initially went to Quark's after arriving on the station and played multiple rounds of dabo. They won a great deal of latinum, until Quark instructed Broik to fix the table so that Falow would lose. Enraged, Falow told Quark he now had to play one of his games.
